As a common equipment for solid and liquid separation, filter housing is widely used in pharmaceutical, food, chemical and other industries. In recent years, with the increasingly severe environmental pollution problems, the market demand for filter housings has become more vigorous. At present, there are many kinds of bag filter housings on the market, mainly including stainless steel bag filter housing, carbon steel bag filter housing, FRP bag filter housing, and PPH bag filter housing. The PPH bag filter housing is a filter system made of PP reinforced polypropylene material (Polypropylene Homopolymer). With the excellent chemical resistance of the PPH material, it can meet the filtration applications of many chemical acid-base liquids, such as seawater, chemical solutions, oil field water injection, circulating cooling water, production water, printing and dyeing textile water and wastewater filtration.
So What are the currently popular PPH Bag Filter Housing Style?
1. Swing Bolt Type PPH Plastic Single Bag Filter Housing
The swing bolt type PPH single bag filter housing adopts one-piece design, the structure is firm and reliable, without any welding points, which completely solves the problem of leakage. The design of screw-locked lid with the lifting ring can meet the convenience of opening and locking the lid in a small space, and the replacement of the filter bag is convenient and quick. The water inlet and outlet are connected by flanges, which are durable and can be used with standard pipe flanges in various countries.
2. Screw Cap Type PPH Plastic Singe Filter Bag Housing
The screw cap type PPH plastic single bag filter housing is designed and manufactured according to international general standards, and can match the filter bags of international famous brands (such as EATON, FSI, PALL, etc.) It contains UV-resistant material, making it durable and suitable for use in all climates. The design of the screw-on top cover makes it possible to assembly and disassembly the filter housing without any tools, and it is convenient and quick to replace the filter bag.
3. PPH Plastic Multi-Bag Polypropylene Filter Housing
The PPH plastic multi bag filter housing could be provided with 2 bags, 3 bags and 4 bags to meet different flow requirement. The flow capacity could reach from 40m³/h to 160m³/h. There is a sealing design between the ring opening of the filter bag and and the inner wall of the basket, and there is also a sealing design between the outer wall of the upper opening of the basket and the inner wall of the barrel, which effectively prevents internal leakage of the barrel and meets the requirements of precision filtration.
4. Top Entrying Type PPH Plastic Single Filter Bag Housing
The upper cover of the top entrying type PPH plastic single filter bag housing is integrally formed by casting mold, so that the filter housing can withstand high pressure filtration. The filter bag is supported by a plastic basket inside, the liquid flows in from the inlet, and flows out after being filtered by the filter bag. Impurities are intercepted in the filter bag, and the filter bag can continue be used after replacement. This model is specially designed and produced for high temperature, acid and alkali resistance requirement applications.
Hongtek is a leading manufacturer for PPH plastic bag filter housing and cartridge filter housing, which with advantages of acid and alkali resistance, high temperature resistance, good softness and easy molding. The PPH bag filter housing makes up for the shortcomings of ordinary plastic and stainless steel filter housing, now are widely used in fields as industrial wastewater, seawater desalination, chemical industry, electroplating filtration industry, petrochemical, metal processing etc..
