Key features

✅ High Throughput, Less Intervention - Compared to single-bag systems, multi-bag systems significantly increase waste handling capacity while reducing replacement frequency and labor costs.

✅ Scalable To Your Process - Modular design adapts from small rail installations to plant-wide deployments (2 → 40+ bags).

✅ Robust Materials and Surface Finishes - Standard 304/316L stainless steel; titanium, Hastelloy, and other alloys available for corrosive chemicals. Electropolishing and protective coatings extend service life.

✅ Pressure Performance Options - Configurable for low- and high-pressure operations with rated pressure classes of 7, 10, 20 bar, ensuring structural integrity and safety.

✅ Maintainability - Features like rotating bolt covers and spring-assisted lifting mechanisms enable tool-free, safe, and effortless filter bag replacement, minimizing downtime.

How It Works

Untreated process liquid enters the pressurized housing and is directed into the interior of each individual filter bag.
The liquid is forced from the inside to the outside of the filter bags. The bag material acts as a precision screen, capturing all solid contaminants and particles within the bag's interior.
The purified liquid, free of particulates, exits through the fine mesh of the bag and collects in the clean, common chamber of the housing before exiting through the outlet port.

Applications

Multiple-bag filter housings are used wherever large volumes of liquid must be clarified or protected downstream equipment:

Municipal & industrial water treatment (raw, process, cooling, potable, seawater)
Wastewater and reuse / effluent polishing
Food & beverage process filtration (bulk clarifying, ingredient protection)
Chemical processing and solvent handling
Oil & gas, petrochemicals and refineries
Power generation and cooling circuits
Shipboard / marine and offshore systems
Automotive, metalworking, paints & inks, and general process industries
