A stainless steel single bag filter housing typically costs from several hundred dollars for a basic factory-direct industrial unit to several thousand dollars for a branded, high-pressure, sanitary, certified, or highly customized model.
In the U.S. retail market, standard industrial stainless steel single bag filter housings commonly appear in the US$1,400 to US$6,500+ range, while factory-direct pricing can differ significantly depending on material, design, quantity and customization.
The final price depends primarily on:
- SS304 or SS316L construction
- Size #1 or Size #2 filter bag
- Operating and design pressure
- Threaded, flanged or Tri-Clamp connections
- Inlet and outlet size
- Closure design
- Surface finish
- Gasket material
- Accessories
- Testing and certification
- Order quantity
- OEM or custom fabrication requirements
This guide explains how much a stainless steel single bag filter housing costs, what determines the price, and how to compare quotations correctly.
Quick Answer: Stainless Steel Single Bag Filter Housing Price
For budgeting purposes, buyers should think in terms of configuration rather than one fixed price.
| Housing Type | Relative Price Level | Typical Application |
|---|---|---|
| Basic SS304 Size #1 | $ | General water and industrial filtration |
| Basic SS304 Size #2 | $$ | Medium-flow industrial filtration |
| SS316L Size #1 | $$ | Corrosive or hygienic applications |
| SS316L Size #2 | $$$ | Chemical, food and industrial processing |
| High-pressure housing | $$$ | Pressurized industrial systems |
| Sanitary polished housing | $$$–$$$$ | Food, beverage and pharmaceutical |
| ASME/PED or project-certified housing | $$$$ | Regulated industrial projects |
| Fully customized OEM housing | Depends on specification | Equipment manufacturers and engineering projects |
There is no universal price because two housings that look almost identical may have very different:
- Stainless steel grades
- Material thicknesses
- Pressure ratings
- Welding requirements
- Flange standards
- Surface finishes
- Inspection requirements
A useful quotation must therefore be based on the same technical specification.
Why Can One Single Bag Filter Housing Cost $800 and Another $5,000?
This is one of the most important questions for industrial buyers.
At first glance, two stainless steel housings may look almost identical:
- Cylindrical stainless steel body
- One lid
- One inlet
- One outlet
- Three support legs
- One filter basket
But their technical specifications may be completely different.
For example:
Housing A
- SS304
- Size #1
- Low-pressure application
- 2-inch threaded connection
- Standard industrial surface
- Basic closure
- No special certification
Housing B
- SS316L
- Size #2
- 10 bar design pressure
- DN50 PN16 flanges
- Heavy-duty swing-bolt closure
- Polished internal surface
- EPDM seal
- Pressure testing
- Material certification
- Customized drawing
Housing B naturally costs more.
Therefore:
Do not compare bag filter housing prices until you compare the specifications behind the prices.
1. SS304 vs SS316L: How Much Does Material Affect the Price?
Material is one of the first factors affecting the price of a stainless steel bag filter housing.
SS304 Single Bag Filter Housing
SS304 is widely used for:
- Industrial water
- Cooling water
- Process water
- Paint
- Ink
- Lubricants
- General liquid filtration
It is usually the more economical stainless steel option.
For applications where corrosion resistance requirements are moderate, SS304 often provides a good balance between:
Cost + durability + corrosion resistance
SS316L Single Bag Filter Housing
SS316L normally costs more because the raw material is more expensive and is selected for applications requiring better corrosion resistance.
Typical applications include:
- Chemical processing
- Food and beverage
- Pharmaceutical processing
- High-purity water
- Certain solvents
- Certain acidic or saline liquids
However, buying SS316L does not automatically mean the housing is suitable for every chemical.
Before purchasing, provide:
- Chemical name
- Concentration
- Operating temperature
- Operating pressure
The compatibility of the housing, gasket and filter bag should all be checked.
Does SS316L Cost Much More Than SS304?
Usually yes, but the difference in the finished housing is not determined only by the raw stainless steel price.
Fabrication, welding, polishing, wall thickness, fittings and testing can represent a significant part of total manufacturing cost.
Therefore, a buyer should not assume:
SS316L housing price = SS304 housing price + material difference only.
2. Size #1 vs Size #2: Which Costs More?
Size #1 and Size #2 are two of the most common industrial liquid filter bag sizes.
Typical dimensions are approximately:
| Filter Bag Size | Diameter | Length |
| Size #1 | 180 mm / 7 in | 430–440 mm / 17 in |
| Size #2 | 180 mm / 7 in | 810 mm / 32 in |
A Size #2 single bag filter housing generally costs more than a Size #1 housing because:
- The vessel body is longer
- More stainless steel is required
- The support basket is larger
- The total housing weight is higher
- Fabrication time may be greater
However, Size #2 also provides a larger filtration area.
For many industrial applications, that can mean:
- Higher usable flow
- Greater dirt-holding capacity
- Longer filter bag life
- Fewer bag changes
Therefore, choosing the cheaper Size #1 housing may not always result in the lowest operating cost.
3. How Does Flow Rate Affect the Housing Price?
A common buyer question is:
“I need 30 m³/h. How much will the housing cost?”
Flow rate alone is not enough to determine price.
A 30 m³/h application should also consider:
- Liquid viscosity
- Micron rating
- Particle concentration
- Filter bag material
- Inlet/outlet size
- Allowable differential pressure
For example:
Application A
Water
30 m³/h
100 micron
Low contamination
Application B
Resin
30 m³/h
5 micron
High viscosity
These two applications should not automatically use the same housing.
Application B may require:
- Larger filtration area
- Larger connections
- Reduced face velocity
- Multi-bag housing instead of single bag
That changes the price significantly.
4. How Much Does Pressure Rating Affect the Cost?
Pressure is one of the biggest reasons two filter housings can have very different prices.
A housing designed for relatively low pressure may require:
- Thinner material
- Simpler closure
- Lighter flanges
A higher-pressure housing may require:
- Increased wall thickness
- Stronger cover
- Heavy-duty eye bolts
- Larger flange thickness
- Stronger welds
- Additional testing
For reference, industrial single-bag models in the market are available around the 100–150 psi range, but the actual pressure rating must always be confirmed for the specific model.
Do not confuse:
Operating Pressure
Normal system operating pressure.
with:
Design Pressure
The pressure used as the engineering basis for designing the vessel.
and:
Test Pressure
The pressure used during pressure testing.
They are not necessarily the same number.
5. Threaded vs Flanged vs Tri-Clamp: Which Costs More?
Connection type also affects the price.
Threaded Connections
Examples:
- NPT
- BSP
These are commonly used for smaller or general-purpose industrial systems.
They are usually among the more economical configurations.
Flanged Connections
Examples:
- ANSI / ASME
- DIN / EN
- JIS
- GB
Common sizes include:
- DN40
- DN50
- DN65
- DN80
Flanged housings normally cost more because the flanges themselves add:
- Material
- Weight
- Welding
- Machining
- Inspection requirements
A quotation should clearly state both:
Connection size + flange standard
For example:
DN50 PN16
is more useful than:
2-inch flange
Tri-Clamp Connections
Tri-Clamp connections are common in:
- Food processing
- Beverage
- Pharmaceutical
- Sanitary applications
The housing may also require a higher-quality internal surface finish, which further increases the price.
6. How Much More Does a Sanitary Bag Filter Housing Cost?
A sanitary stainless steel bag filter housing normally costs more than a standard industrial housing.
Why?
Because sanitary construction may require:
- SS316L
- Improved weld finishing
- Internal mechanical polishing
- Reduced dead zones
- Sanitary fittings
- Tri-Clamp connections
- Food-grade seals
- Improved drainage
- Higher surface-finish requirements
The surface finish may be specified using roughness requirements such as Ra values.
The tighter the manufacturing and finishing requirements, the higher the fabrication cost.
For food, beverage or pharmaceutical applications, do not compare a sanitary housing directly with an ordinary industrial sandblasted housing.
They are different products even if they both use one Size #2 filter bag.
7. Does the Lid or Closure Design Affect Price?
Yes.
Common closure systems include:
- V-clamp
- Swing bolts
- Eye bolts
- Multiple bolts
- Quick-opening mechanisms
A basic V-clamp can be economical and convenient for appropriate lower-pressure applications.
Heavy-duty swing-bolt or eye-bolt closures generally cost more but may be required for:
- Higher pressure
- Larger vessels
- Industrial safety requirements
- Frequent opening and closing
For applications where filter bags are replaced often, closure design also affects labor cost.
A cheaper housing that takes significantly longer to open may cost more over its service life.
8. Which Accessories Increase the Price?
A basic quotation may include only:
- Housing
- Lid
- Support basket
- Legs
- Standard seal
Optional accessories may include:
Pressure Gauge
Used to monitor system pressure.
Differential Pressure Gauge
Useful for monitoring pressure difference across the filter.
Vent Valve
Allows trapped air to be released.
Drain Valve
Allows easier emptying and maintenance.
Adjustable Legs
Useful when matching existing pipeline height.
Casters
Useful for portable filtration systems.
Safety Interlock
Used in certain applications to improve operational safety.
Heating Jacket
Used when liquid temperature must be maintained.
Magnetic Inserts
Used where removal of ferrous particles is required.
Each additional accessory increases the total system price.
9. How Much Does Surface Treatment Affect Price?
Surface treatment is another important quotation variable.
Common options include:
Standard Industrial Finish
Suitable for many general applications.
Sandblasting / Bead Blasting
Produces a uniform industrial appearance.
Mechanical Polishing
Used when smoother surfaces are required.
Internal Polishing
Common in hygienic or high-purity applications.
Mirror Polishing
More labor-intensive and therefore more expensive.
If you receive two SS316L quotations with substantially different prices, check the specified internal and external surface treatment.
This alone can explain part of the price difference.
10. Does Wall Thickness Matter?
Yes—significantly.
A low price does not necessarily mean the supplier is using the same amount of stainless steel.
Ask for:
- Body thickness
- Cover thickness
- Bottom thickness
- Flange specification
- Material grade
The required thickness depends on factors such as:
- Vessel diameter
- Pressure
- Temperature
- Material
- Construction method
- Applicable engineering standard
For pressure equipment, thickness should be determined by appropriate engineering design rather than selected only to reduce cost.
11. Does Welding Quality Affect the Price?
Yes.
A stainless steel filter housing is a fabricated pressure-containing product.
Important welding areas include:
- Body seams
- Bottom connection
- Inlet nozzle
- Outlet nozzle
- Vent port
- Drain port
- Support legs
Higher fabrication standards generally require:
- Skilled welders
- Better welding control
- More finishing time
- Inspection
- Cleaning or passivation
A very low-priced housing may look attractive in product photographs, but welding quality is much more important than appearance alone.
Ask the supplier for close-up photographs of actual production units.
12. Does Pressure Testing Add Cost?
Depending on supplier and specification, basic pressure testing may already be included.
Projects may additionally require:
- Hydrostatic pressure test
- Pneumatic leak test
- Test certificate
- Witness inspection
- Third-party inspection
The more extensive the testing and documentation, the greater the total project cost.
Before ordering, specify whether you require a formal pressure test report.
13. What Documentation Can Increase the Price?
Standard industrial purchases may require only:
- Commercial invoice
- Packing list
- Product drawing
More demanding projects may request:
- Material certificate
- EN 10204 material documentation
- Pressure test report
- Welding documentation
- Dimensional inspection report
- Surface finish report
- Certificate of conformity
- Third-party inspection
If these documents are required, tell the supplier before quotation, not after production.
Some documents require traceability that must begin when raw materials are purchased.
14. Factory-Direct vs Distributor Price
Another major price difference comes from where you purchase the housing.
Buying From a Local Distributor
The price may include:
- Distributor margin
- Local inventory
- Warehousing
- Domestic freight
- Technical support
- Faster delivery
- Warranty support
This can result in a higher purchase price, but it may be worthwhile when you need immediate local availability.
Buying Directly From a Manufacturer
Factory-direct purchasing can be more economical for:
- Multiple units
- OEM projects
- Custom housings
- Engineering projects
- Private labels
- International distributors
You may also have more flexibility in:
- Material
- Dimensions
- Connections
- Surface finishing
- Accessories
However, remember to consider:
Factory price + shipping + import duties + local taxes + customs clearance
when comparing total landed cost.
15. China Factory Price vs U.S. Distributor Price
This is another frequent purchasing question.
A Chinese factory quotation may appear much lower than a U.S. distributor quotation, but the buyer should check whether the specifications are actually equivalent.
Compare:
| Specification | Supplier A | Supplier B |
| Material | SS304 | SS316L |
| Bag Size | #1 | #2 |
| Pressure | 6 bar | 10 bar |
| Connection | Thread | ANSI flange |
| Closure | Clamp | Swing bolts |
| Surface | Industrial | Polished |
| Gauge | No | Yes |
| Test Report | No | Included |
| Material Certificate | No | Included |
If these specifications differ, comparing the final prices is meaningless.
The correct question is not:
“Which supplier is cheaper?”
It is:
“Which supplier offers the better price for the same specification?”
16. How Much Is an SS304 Size #2 Single Bag Filter Housing?
There is no universal fixed price.
For an accurate quotation, a manufacturer needs to know at least:
- Material: SS304
- Bag: Size #2
- Pressure
- Connection size
- Connection type
- Surface finish
- Quantity
For example:
SS304
Size #2
6 bar operating pressure
DN50 PN16
Side-in / bottom-out
Standard industrial finish
5 units
can be quoted much more accurately than simply asking:
“Price for Size #2?”
17. How Much Is an SS316L Size #2 Single Bag Filter Housing?
The same principle applies to SS316L.
A standard industrial SS316L Size #2 housing and a sanitary SS316L Size #2 housing may have dramatically different prices.
For example:
Industrial Version
- SS316L
- Size #2
- Side-in / bottom-out
- Standard flange
- Sandblasted
- Standard O-ring
Sanitary Version
- SS316L
- Size #2
- Top-entry
- Tri-Clamp
- Polished interior
- Sanitary gasket
- Improved drainage
- Specified surface roughness
Both products may appear under the keyword:
316L single bag filter housing
but they should not have the same price.
18. Is the Filter Bag Included in the Housing Price?
Not always.
Ask the supplier whether the quotation includes:
- Filter bag
- Support basket
- O-ring
- Pressure gauge
- Vent valve
- Drain valve
The stainless steel support basket is normally part of the housing assembly, while disposable filter bags may be quoted separately.
Filter bag prices depend on:
- Material
- Size
- Micron rating
- Ring type
- Seam construction
- Quantity
Common media include:
- PP felt
- PE felt
- Nylon mesh
- PP mesh
- PTFE
It is often practical to purchase the first batch of filter bags together with the housing.
19. Should You Choose the Cheapest Single Bag Filter Housing?
Usually not without comparing specifications.
A low purchase price can become expensive if the housing has:
- Incorrect connection size
- Insufficient flow capacity
- Excessive pressure drop
- Wrong material
- Incompatible gasket
- Poor weld quality
- Difficult bag replacement
- No replacement seals
- Inadequate pressure rating
The correct objective is not the lowest purchase price.
It is the lowest total cost of ownership for a housing that safely meets the process conditions.
20. How Can You Reduce the Cost Without Reducing Quality?
There are several practical ways.
1. Do Not Over-Specify Material
If SS304 is fully suitable, specifying SS316L may add unnecessary cost.
2. Select the Correct Pressure Rating
Do not unnecessarily specify an extremely high pressure rating for a low-pressure application.
At the same time, never reduce pressure rating below safe engineering requirements to save money.
3. Use Standard Connections
Standard flange and thread configurations are generally less expensive than unusual custom connections.
4. Order Multiple Units Together
Manufacturing setup costs can be distributed across a larger quantity.
5. Standardize Your Housing Design
OEM buyers can reduce long-term costs by using one standard configuration across multiple machines.
6. Purchase Replacement Bags Together
Combining housings and filter bags can simplify shipping and procurement.
21. What Information Do I Need for an Accurate Price?

22. Example: How to Request a Price
A weak RFQ looks like this:
Hi, please send your best price for stainless steel single bag filter housing.
The supplier cannot know what you actually need.
A better RFQ is:
Please quote a stainless steel single bag filter housing with the following specification:
Liquid: Process water
Flow rate: 25 m³/h
Filtration rating: 10 micron
Operating pressure: 4 bar
Maximum pressure: 6 bar
Temperature: 40°C
Housing material: SS304
Bag size: Size #2
Connection: DN50 PN16 flange
Flow direction: Side-in / bottom-out
Seal: EPDM
Quantity: 5 unitsPlease include the filter housing drawing, recommended filter bag, lead time and pressure test information.
This makes it possible for suppliers to provide comparable quotations.
23. Example Price Comparison: Do Not Look at Price Alone
Suppose you receive three quotations:
| Supplier | Price | Specification |
| Supplier A | Lowest | SS304, threaded, lower pressure |
| Supplier B | Medium | SS304, DN50 flange, industrial construction |
| Supplier C | Highest | SS316L, higher pressure, polished, certified |
It would be incorrect to conclude:
Supplier A is the cheapest supplier.
Supplier A is actually offering a different product.
First standardize:
- Material
- Size
- Pressure
- Flange
- Seal
- Finish
- Accessories
- Documentation
Then compare price.
This is one of the most effective ways to avoid purchasing mistakes.
24. When Is a Single Bag Filter Housing No Longer the Cheapest Solution?
Sometimes the cheapest solution is not a single bag housing at all.
Suppose your required flow is very high.
Forcing the full flow through one Size #2 bag may lead to:
- High differential pressure
- Short filter bag life
- Frequent replacement
- Production downtime
In that situation, a:
2-bag, 3-bag, 4-bag or multi-bag filter housing
may cost more initially but reduce operating costs.
The correct economic comparison should include:
Housing Cost + Filter Bag Cost + Labor + Downtime + Pressure Loss
not just the initial equipment price.
25. What Is the Total Cost of Ownership?
Consider this simplified example.
Housing A
Initial cost: lower
Filter bag replacement: every 2 days
Housing B
Initial cost: higher
Filter bag replacement: every 7 days
After one year, Housing B may be the less expensive filtration solution because it uses fewer bags and requires less labor.
For industrial filtration, purchasing decisions should therefore consider:
CAPEX
Initial equipment cost
plus
OPEX
- Replacement filter bags
- Labor
- Cleaning
- Downtime
- Energy consumption
- Spare parts
A technically correct housing can often provide better long-term value than the lowest-cost housing.
26. How Much Does a Custom Stainless Steel Bag Filter Housing Cost?
Custom housing prices depend on how far the design differs from a standard model.
Common customization includes:
- Custom vessel height
- Custom diameter
- DN40/DN50/DN65/DN80 connections
- ANSI flange
- DIN flange
- Tri-Clamp
- Top-entry
- Side-entry
- Special drain
- Special vent
- Adjustable legs
- Jacketed body
- Portable cart
- Internal polishing
- Special gaskets
- Special pressure ratings
Minor modifications may have a limited impact on the price.
A completely custom pressure vessel can require additional:
- Engineering
- Drawings
- Material
- Fabrication
- Testing
and therefore cost considerably more.
27. How Much Should You Budget?
For preliminary budgeting, think of stainless steel single bag filter housings in three broad categories.
Economy / Standard Industrial
Best for:
- General water
- OEM equipment
- Normal industrial processes
- Standard connections
- Standard pressure
Price priority: Cost efficiency
Heavy-Duty Industrial
Best for:
- Chemical processing
- Higher pressure
- Higher temperature
- Heavy industrial use
- Frequent bag changes
Price priority:
Strength + reliability + serviceability
Sanitary / Certified / Engineered
Best for:
- Food
- Beverage
- Pharmaceutical
- Regulated projects
- Special pressure vessel requirements
Price priority:
Compliance + finish + documentation + process safety
The more the application moves from general industrial use toward specialized engineering requirements, the more expensive the housing becomes.
28. How to Get a Stainless Steel Single Bag Filter Housing Price From Ince Filter

Process Water / 25 m³/h / 10 μm / 4 bar / 40°C / SS304 / DN50 PN16 / 5 units
This is usually enough information to begin technical selection and prepare a meaningful quotation.
Frequently Asked Questions
How much does a stainless steel single bag filter housing cost?
The price can range from several hundred dollars for simpler factory-direct industrial models to several thousand dollars for branded, high-pressure, sanitary or certified housings. U.S. retail prices for industrial stainless steel single bag housings commonly fall into roughly the $1,400–$6,500+ range, depending on specification.
Why are stainless steel bag filter housings so expensive?
The cost includes more than stainless steel. Fabrication, welding, pressure-rated closures, flanges, support baskets, surface finishing, testing, engineering and certification can all contribute significantly to the final price.
Is an SS316L bag filter housing more expensive than SS304?
Normally yes. SS316L raw material costs more and is commonly selected for higher-corrosion-resistance applications. The total price difference also depends on wall thickness, fittings, polishing and fabrication requirements.
