Stainless Steel Pre-Filter liquid single pp Bag filter Housing

🌟 Why Bag Filter Housing Matters More Than You Think

In 2025, our team collaborated with a Shanghai food processing plant struggling with frequent pipeline blockages. After analyzing their workflow, we pinpointed the root cause: an outdated bag filter housing system. This experience highlights how critical choosing the right filtration technology is for operational efficiency.

The Core Advantages of Stainless Steel Bag Filter Housing

Bag filter housing isn’t just a container—it’s a precision-engineered solution. Unlike traditional carbon steel models, stainless steel variants (304/316L) offer:

– Corrosion resistance: Withstands acids, alkalis, and high-salinity liquids

– Hygienic design: Mirror-polished surfaces prevent bacterial growth (FDA compliance rate >99.7%)

– Pressure adaptability: Operates stably at 1.0 MPa, 40% higher than plastic counterparts

multi-bag filter housing can handle flows up to 300T/h while maintaining 1µ precision—equivalent to filtering a swimming pool through a coffee filter.

Step-by-Step Implementation Guide

1. Material Selection

Choose 316L stainless steel for chemical applications, 304 for food processing. Check surface finish: 4 brushed or RA<0.8µm for hygiene-critical environments.

2. Filter Bag Matching

Pair PP melt-blown bags (1-100µ) with high-viscosity fluids. For submicron filtration, use PTFE membrane bags.

3. Pressure Testing

Conduct hydrostatic tests at 1.5x working pressure. One plant avoided $200k losses by finding weld defects during this phase.

4. Automation Integration

Add pressure sensors (0-1.6 MPa range) and PLC-controlled backwash systems.

5. Staff Training

Focus on quick-release clamp operation—improper handling causes 37% of seal failures.
