PP bag filter housings offer superior chemical resistance, making them ideal for handling corrosive fluids, acids, and alkalis where stainless steel might corrode. Being 100% polypropylene, they are also more cost-effective, lighter, and feature a seamless, one-piece injection-molded design that eliminates potential leakage points and dead corners, ensuring a cleaner filtration process for sensitive applications like pharmaceutical or electronic-grade water.
Standard PP bag filter housings are designed to handle temperatures below 90°C. For industrial applications requiring higher temperature stability while maintaining chemical resistance, we offer specialized versions made of PPR (random copolymer polypropylene). We recommend checking your system's peak operating temperature against our specification sheet to ensure optimal performance.
Yes, our housing is engineered with a double-standard design. It is highly versatile and allows you to use either standard filter bags or filter cartridges within the same housing. This flexibility makes it a practical solution for industrial plants that need to switch between different filtration media based on changing process requirements.
The selection of micron rating (1-500 μm) depends on the size of the impurities you need to remove and the required purity of the filtrate. For pre-filtration (e.g., protecting an RO membrane), a higher micron rating is often sufficient. For final polishing in pharmaceutical or high-precision chemical applications, a finer rating (1-10 μm) is recommended. Our team can help you analyze your slurry or liquid properties to recommend the exact precision needed.
Maintenance is minimal due to the seamless, one-piece construction. The shell has no grooves or dead corners, which prevents the accumulation of debris and simplifies cleaning. During routine maintenance, simply depressurize the system, open the lid, and easily replace the filter bag or cartridge. Since there are no welded joints, the risk of structural failure over time is significantly lower compared to metal housings.
