Parallel bag filtration
The liquid is distributed through three bag-and-basket assemblies before reaching the outlet. Three parallel bags increase available filtration area relative to one equivalent bag.

3 Bag Filter Housing
The INCE-MB-03 3-bag filter housing holds three filter bags in parallel inside one stainless steel vessel for industrial liquid filtration. This three-bag filter housing is available in 304 or 316L stainless steel, with a listed Ø450 mm barrel, DN100 flanged connections and 90 T/H reference flow.
Select the housing together with the bag media, retention target and process conditions to establish a practical operating duty.

Stainless Steel Three-Bag Filter Housing
Stainless steel construction
The series offers 304 and 316L stainless steel. Select the alloy and gasket against the complete fluid chemistry, concentration, temperature and cleaning requirements.
Serviceable cover arrangement
The series uses a davit-arm cover arrangement to assist handling. Confirm access space, lifting clearance and the final cover mechanism for the ordered model.
3 Bag Filter Housing Specifications — INCE-MB-03
Model-specific values below are taken from the existing Incefiltration multi-bag product table. Series-level options require confirmation for the final assembly.
| Parameter | Reference / selection |
|---|---|
| Model | INCE-MB-03 |
| Bag quantity | 3 bags in one vessel |
| Barrel diameter | Ø450 mm |
| Inlet / outlet | DN100 flange — confirm flange standard and orientation |
| Reference flow | 90 T/H — subject to fluid and filtration conditions |
| Listed wall thickness | 3.0 mm — final construction per approved design |
| Material options | 304 stainless steel / 316L stainless steel |
| Series design-pressure reference | 1.0 MPa — confirm final vessel rating and design temperature |
| Series operating-temperature reference | Up to 130°C — subject to bag, seal, liquid and vessel limits |
| Seal options | Silicone / FKM / PTFE / EPDM, subject to compatibility |
| Surface finish | Mechanical polishing / sandblasting |
| Bag dimensions and filtration area | Confirm with basket and collar drawings; not specified in the current model row |
Design pressure, operating pressure, temperature and bag differential-pressure limits are different specifications. The 1.0 MPa and 130°C series references do not establish a simultaneous operating rating. Final limits follow the approved design, nameplate and component specifications.
How to Size a 3 Bag Filter Housing
Start with the liquid
Provide normal and peak flow, density, viscosity, temperature and liquid composition. Viscous liquids cannot be sized from a water-like reference flow alone.
Define the filtration duty
State micron rating, required capture efficiency, solids concentration and desired service interval. Select compatible media and establish acceptable clean and terminal pressure drop.
Confirm the installation
Check nozzle standard, pipe size, footprint, drain and vent positions, lid clearance, basket removal height and access for bag changes.
Understanding 90 T/H: this is the listed mass-flow reference. For liquid density ρ in tonnes/m³, volume flow is Q = 90 ÷ ρ m³/h. Water near 1 tonne/m³ gives approximately 90 m³/h, but this conversion does not validate the housing's capacity for a particular filtration duty.
2 vs. 3 vs. 4 Bag Filter Housing
Compare the listed model dimensions and reference flows before checking your actual filtration duty. More bags do not guarantee a proportional increase in usable flow: bag dimensions, micron rating, viscosity, solids loading and allowable pressure drop remain part of the selection.
| Model | Bags | Barrel | Connection | Reference flow |
|---|---|---|---|---|
| INCE-MB-02 | 2 | Ø400 mm | DN80 flange | 60 T/H |
| INCE-MB-03 | 3 | Ø450 mm | DN100 flange | 90 T/H |
| INCE-MB-04 | 4 | Ø500 mm | DN125 flange | 120 T/H |
When should you consider a three-bag vessel?
Evaluate INCE-MB-03 when selecting between the two-bag and four-bag configurations and the installation can accommodate its Ø450 mm barrel and DN100 connections. Confirm total footprint, basket removal clearance and pressure-drop performance on the proposed assembly before ordering.
Three bags operate in parallel in one vessel. They do not form three sequential filtration stages, and the complete vessel must be isolated for a bag change.
304 / 316L Stainless Steel Housing Options
Bag media & micron rating
Select the media for chemical compatibility and retention requirements. The housing does not determine filtration micron rating. Confirm bag length, collar profile and basket support.
Connections & seals
DN100 flange is the listed INCE-MB-03 connection. Specify the flange standard, pressure class and orientation; discuss alternatives separately. Select a compatible gasket.
Finish & documentation
The series lists mechanical polishing and sandblasting. Specify any surface-finish, inspection, material traceability or pressure-vessel documentation requirements before quotation.
3 Bag Filter Housing Applications
Process water
Particulate removal before downstream equipment, subject to the required particle size and actual solids loading.
Coatings & compatible chemicals
Removal of process debris or agglomerates after assessing chemical compatibility and product viscosity.
Cooling & working fluids
Screening compatible circulating liquids to reduce larger contaminants before sensitive process equipment.
Food & beverage process liquids
Evaluate only with suitable wetted materials, seals, finish and required food-contact documentation.
Pre-filtration
Use as a selected stage before finer filtration. Three bags in parallel do not provide coarse-to-fine staging.
OEM filtration skids
Integrate with piping, valves and instruments according to the process duty and maintenance-access requirements.
Plan for Safe Bag Changes
Monitor differential pressure across the filter and use the limits specified for the bags and vessel. For bag replacement, follow the equipment procedure: stop flow, isolate the vessel, relieve pressure, verify zero pressure, cool and drain as required, then open the cover. Inspect the baskets and seals before installing a matched set of replacement bags.
A davit arm assists cover handling; it does not permit opening a pressurized vessel. Confirm vent, drain, isolation and lifting provisions in the installation design.
3 Bag Filter Housing FAQ
What is a 3 bag filter housing?
It is a single vessel containing three filter bags in parallel, each supported by a basket. The bags normally share the same inlet and outlet; this is not a two-stage series filtration arrangement.
Does three-bag capacity specify the filter bag size?
No. Three bags describes the number of bags inside the vessel. Size #2 describes a bag size. Confirm the required bag dimensions, collar and basket depth on the approved drawing.
Is this a duplex filter for continuous operation?
Not by itself. A three-bag vessel has a common pressure boundary and must be isolated and depressurized for servicing. Uninterrupted changeover requires a separately designed duplex arrangement with isolation and changeover valves.
Does INCE-MB-03 guarantee 90 m³/h?
The existing product table lists 90 T/H as reference flow, not a guaranteed operating duty. For water near 1 t/m³ this is approximately 90 m³/h. Actual capacity depends on viscosity, density, bag media, micron rating, solids loading and allowable pressure drop.
Can the housing use different micron-rated bags together?
Parallel bags do not create sequential filtration stages. Use a matched set for a defined filtration duty unless an engineered design specifies otherwise. For coarse-to-fine filtration, evaluate separate stages in series.
Which stainless steel and gasket should I choose?
The series lists 304 and 316L stainless steel with silicone, FKM, PTFE or EPDM seal options. Selection depends on the complete liquid composition, concentration, temperature and cleaning regime. Confirm the final assembly limits and documentation in the quotation.
