Premium #2 Bag Filter Housing for Precision Filtration
In demanding industrial, water treatment, and manufacturing processes, even a brief interruption in filtration can lead to costly downtime, product contamination, and equipment wear. Selecting the right vessel for your filter bags is therefore vital. Our #2 bag filter housing combines rugged construction, optimized flow design, and easy maintenance to keep your operations running smoothly and your fluids consistently clean.
Heavy-Duty Construction and Material Excellence
Stainless Steel Durability: Each #2 bag filter housing is crafted in 304 or 316L stainless steel to resist corrosion, abrasion, and thermal stress. Whether handling acidic process streams or high-temperature fluids, you can trust the vessel’s integrity over years of service.
Precision Welding and Support: Full-penetration welds, reinforced leg supports, and a thick shell wall ensure the housing remains rigid even under full pressure and high flow rates. This robust framework prevents deformation and guarantees reliable sealing.
Polished Interior Finish: A smooth, mirror-like interior finish (Ra ≤ 0.8 µm) minimizes particle hang-up, simplifies cleaning, and prevents microbial growth—especially critical in hygienic or sanitary applications.
Optimized Flow Path for Maximum Performance
Advanced Manifold Design: The internal manifold of our #2 bag filter housing distributes fluid uniformly across the entire filter bag surface, eliminating channeling and ensuring every inch of media contributes to contaminant removal.
Reduced Pressure Drop: By smoothing turbulence and guiding flow, the vessel achieves lower differential pressures compared to traditional designs. This means your pumps work less, saving energy and reducing operational costs over time.
Enhanced Media Utilization: Even distribution extends the life of each filter bag, so you replace bags less often. Fewer change-outs translate directly into reduced downtime and labor expenses.
User-Friendly Maintenance Features
Quick-Open Closure System: Ergonomic clamp or eyebolt closures on the #2 bag filter housing allow technicians to open and close the vessel swiftly without special tools. Change-out times shrink by up to 50%, keeping maintenance windows brief.
Hinged or Lift-Off Lid Options: Choose between a swing-bolt hinged lid for controlled opening or a lift-off design for maximum clearance—both provide safe access and reduce the risk of accidental drops or leaks.
Clear Sealing Grooves: Precision-machined sealing grooves ensure the gasket seats perfectly every time. Color-coded alignment marks simplify reassembly, guaranteeing a leak-free seal on every service.
Flexible Configurations to Match Any Application
Single-Bag vs Multi-Bag: Our standard #2 bag filter housing accommodates one filter bag, ideal for flows up to 150 GPM. For higher volumes, multi-bag assemblies using the same #2 size media can be configured in parallel.
Top-Entry or Side-Entry Access: Vertically mounted top-entry models save floor space and simplify gravity-drain procedures, while side-entry housings fit under low ceilings or within skid systems.
Custom Inlet/Outlet Positions: Swivel connections, 90° elbows, or straight-through ports let you integrate the housing seamlessly into complex piping layouts without extra fittings.
Sanitary and Industrial Options: Polished internals, tri-clamp fittings, and FDA-approved gaskets are available for food, beverage, and pharmaceutical uses, while standard fittings suit chemical, petrochemical, and general industrial streams.
Safety and Compliance Built In
Pressure Relief and Venting: Standard vent and drain ports let you purge air and depressurize the vessel safely before opening. Optional spring-loaded relief valves add an extra layer of protection.
Certified Welds and Pressure Testing: Every #2 bag filter housing undergoes non-destructive weld inspection and hydrostatic testing per ASME VIII Div. 1 or PED guidelines, ensuring reliable performance under rated conditions.
Traceable Materials: Mill certificates, material traceability logs, and part-by-part documentation support GMP and regulatory audits, making compliance straightforward.
Real-World Application Examples
1. Chemical Batch Filtration
A specialty chemical manufacturer needed precise removal of catalyst residues from reactor effluent. Installing a single-bag #2 bag filter housing upstream of their UV reactor not only captured fine particles but also stabilized downstream flow. Maintenance crews reported a 40% reduction in filter bag swaps and no unplanned shutdowns for over six months.
2. Wastewater Pre-Treatment
A municipal wastewater plant faced fluctuating solids loads during storm surges. Retrofitting several side-entry #2 bag filter housing units before the biological treatment tanks allowed operators to swap bags quickly between shifts, maintaining effluent quality and protecting pumps from grit damage.
3. Paint and Coatings Production
In a high-viscosity coatings plant, abrasive pigments and waxes were eroding their existing filter vessels. The corrosion-resistant and abrasion-tough 316L #2 bag filter housing stood up to the toughest slurries, extending service intervals from one week to over a month.
4. Beverage Clarification
A craft brewery sought an aseptic filtration step before keg filling. Our sanitary top-entry #2 bag filter housing with polished internals and quick-release clamps enabled crew members to perform change-outs in under five minutes—keeping production on schedule and meeting strict cleanliness standards.
#2 Bag Filter Housing Selection Guide
To specify the ideal #2 bag filter housing for your process, evaluate these factors:
Flow Rate Needs
Up to 50 GPM: Single #2 bag housing with standard internals.
50–150 GPM: Single #2 bag vessel with optional flow-enhancement diffuser or multi-bag arrangement in parallel.
Fluid Properties
Clear, low-viscosity fluids: Standard 304 SS.
Abrasive slurries or corrosives: Upgrade to 316L SS or a proprietary alloy.
Operating Temperature and Pressure
Up to 250 °F and 150 PSI: Standard design.
Above these conditions: Specify high-temp gaskets and reinforced clamps.
Sanitary vs Industrial
Food, pharmaceutical, or biotech: Polished Ra ≤ 0.5 µm interior, FDA-approved seals, and tri-clamp fittings.
Industrial chemicals or water treatment: Standard finish with NPT or flange connections.
Maintenance Access
Tight spaces: Side-entry housing reduces vertical clearance.
Overhead piping: Top-entry model with hinged lid eases operation.
Long-Term Value & Return on Investment
Decreased Maintenance Labor: Quick-open closures and guided sealing cut service times, saving hundreds of labor hours annually.
Lower Media Costs: Optimized flow design extends bag life by up to 35%, reducing consumables spend.
Energy Savings: Minimizing pressure drop translates into up to 15% lower pump energy consumption—paying back over the life of the vessel.
Modular Scalability: If throughput increases, parallel #2 bag housings can be added without changing piping layout, protecting your original capital investment.
Consistent Product Quality: Reliable filtration eliminates upstream variances, reducing batch rejections and maintaining brand integrity.
