Products Description

Large bag filter housings for continuous, high-solids process streams. Engineered in SS304/SS316(L) to handle large flows (up to 2,000 m³/h+), extended dirt capacity and fast bag change-minimizing footprint, downtime and operating cost.

How it works

Our large bag filter housings typically operate on a reliable side-in, bottom-out, inside-to-outside flow principle.

The unfiltered liquid enters the housing through a side inlet port, fills the pressure vessel, and is distributed evenly into each filter bag.

Contaminants are captured on the bag's interior surface, while the purified liquid passes through the filter media, into the support basket, and exits through the bottom outlet.

Key Advantages

✅ High throughput in one unit: consolidates multiple single-bag housings to save space and CAPEX.
✅ Large dirt holding: multiple bags give long run-times and fewer service interventions.
✅ Robust internals: perforated plate support baskets prevent bag collapse under high ΔP.
✅ Quick service: top-open quick-release covers or bolt-flange options for rapid, safe bag replacement.
✅ Process flexible: accepts industry-standard 7″ bags (1–1000 µm), multiple flange types and seal materials for broad compatibility.

Applications

✅ Chemical & Petrochemical Processing: Protect sensitive catalysts, heat exchangers, and final product quality by removing particulates from resins, monomers, solvents, and acids. Our housings ensure continuous operation in critical chemical synthesis and separation processes.

✅ Paints, Inks, and Coatings: Achieve flawless final product clarity and color consistency by effectively filtering pigments, gels, and contaminants from viscous liquids. The high dirt-holding capacity is ideal for batch filtration of large volumes.

✅ Industrial Water Treatment: For pre-treatment of feed water or protection of membrane systems (like RO and UF) in large-scale cooling water, process water, and wastewater applications. Our systems handle the high flow rates typical in water treatment plants.

✅ Pharmaceutical & Food & Beverage: While requiring specific certifications, our robust design principles apply to hygienic processes. We can provide solutions for filtering process intermediates and utility water where high flow rates are essential.
