Products Description
Our industrial bag filter housing vessels are designed for high-flow, contamination-sensitive applications. Made from 304 or 316L stainless steel with either a mechanically polished or electropolished finish (sanitary Ra < 0.8 µm is optional), they are engineered to minimize pressure drop while enabling fast, safe bag change-outs. We offer single bag and multi-bag configurations to meet diverse flow requirements.

| Pros | Small footprint, lower capital cost, simplest plumbing. | Higher capacity, lower maintenance frequency, possible staged filtration with different micron bags. |
| Best for | Point-of-use filtration, pilot lines, low-to-moderate flow rates, OEM integration. | Central plant filtration, high solids loads, processes requiring continuous operation (with parallel vessels). |
| Decision factors: flow requirement (GPM / m³/h), required micron rating, allowable ΔP, footprint, and maintenance interval. | ||
Key Advantages
✅ Specification-grade 316L stainless construction → Corrosion resistance and long service life in aggressive chemistries; lowers lifecycle CAPEX.
✅ Modular multi-bag layout (1 / 2 / 4 bags) → Scalable capacity - match filtration area to process demand and minimize footprint.
✅ Low-pressure-drop internal geometry → Higher throughput per bag and reduced pumping energy.
✅ Tool-less quick-change closure option → Rapid bag swaps reduce downtime and operator exposure to process fluids.
✅ Sanitary finishes and CIP compatibility → Meets hygienic requirements for food, beverage and pharma with Ra < 0.8 µm available.
✅ Customizable ports & instrumentation → Install pressure gauges, differential pressure transmitters, sample points and drain/vent to suit process control needs.

FAQ
Q: Can these housings be used for hot fluids?
A: Yes. Standard models are suitable to ~120°C (248°F). For higher temperatures, request high-temp seals and engineered trim. Operating pressure ratings may change with temperature.
Q: Do you offer ASME code vessels?
A: Yes. ASME VIII Div.1 construction and stamping can be supplied as a build option. Provide service conditions at RFQ.
Q: How fast is a bag change?
A: With the quick-release closure and trained personnel, a single bag change can be completed in under 5 minutes (isolated, drained and vented) - actual time depends on site procedures and containment requirements.
