Polypropylene Single Bag Filter Vessel with Screwing Cap

Product Overview

AALfilter’s Polypropylene Single Bag Filter Vessel with threaded cap is a durable and corrosion-resistant solution engineered for demanding wastewater filtration applications. Built from PPH (Polypropylene Homopolymer) using seamless injection molding, the housing eliminates welds and weak points, ensuring leak-proof performance and long-term reliability even under harsh operating conditions.

It is compatible with 5 standard filter bag sizes (#1, #2, #4, #5, #6), offering flexibility to meet various flow rates and particle retention needs in municipal and industrial wastewater treatment systems. This housing is an excellent alternative to stainless steel in corrosive or cost-sensitive environments, delivering superior resistance to chemical degradation, UV exposure, and operating pressures up to 8 bar.

Key Features

✅ Extreme Chemical Resistance: Withstands acids (e.g., sulfuric, hydrochloric), alkalis, and solvents, making it ideal for harsh industrial processes.

✅ Seamless, Leak-Proof Design: One-piece molded construction with Viton® fluoropolymer seals ensures zero side leakage.

✅ Multi-Size Compatibility: Supports filter bags from Size #1 (Φ180x430mm)to Size #6 (Φ180x560mm) for widely applications.

✅ High-Temperature & Pressure Tolerance: Operates at up to  90°C  and 116 psi (8 bar).

✅ Tool-Free Maintenance: Screwing cap design allows quick filter bag replacement without specialized tools.

✅ Smooth Inner Surface: Polished interior prevents residue buildup and simplifies cleaning.

✅ Universal Flange Connections: Compatible with DN40 to DN80 flanges for seamless integration into existing pipelines.

Applications

The PP Bag Filter Housing is engineered for industries requiring precision filtration in corrosive or high-purity environments:

✅ Metal Processing: Filters coolants, lubricants, and metalworking fluids to remove particulates and extend fluid life.

✅ Chemical Manufacturing: Handles aggressive intermediates, catalysts, and solvents in acid/alkali production.

✅ Electroplating: Purifies plating baths by removing impurities like metal ions and sludge.

✅ Pharmaceuticals: Ensures sterility in API (Active Pharmaceutical Ingredient) filtration and CIP (Clean-in-Place) systems.

✅ Inks & Coatings: Removes undispersed pigments and contaminants to enhance product quality.

✅ High-Purity Water Systems: Pre-filters RO (Reverse Osmosis) feed water to protect membranes in desalination or ultrapure water production.

✅ Wastewater Treatment: Processes corrosive industrial effluents to meet environmental discharge standards.
