Considering the need for corrosion resistance in many applications, we have designed and manufactured the PF series offilters. The filter is made of PVDF and PPH material, which is suitable for high temperature and high concentnation ofhydrochloric acid, sulfuric acid, aqua regia and other strong acids and alkalis with strong corosive filtration occasions.

Core Advantages
Filters can be adapted to standard bags 1, 2 and 4.
The filter is integrated injection molding, without any spiral texture andwelding, which ensures the safety and sealing of the product.
The net basket is integrally formed, and the surface of the net basket has aprominent solid square column with unifomm and orderly distribution,which increases the compressive resistance of the net basket.
Quick-open top cover design, no tools are required to open it easily.The support leg of the integral casting is sturdy and sturdy, which makesthe installation more convenient.
Inlet and outlet are available in flange and thread fomms of national standard,American standard, Japanese standard and German standard.
How long is the delivery cycle?
We maintain a consistent 2-week lead time for all filter housings, including standard, multi-bag, and custom units with specialized linings or heating jackets. To ensure quality, every vessel undergoes a 1.5x hydro-pressure test before dispatch.
Are you a direct manufacturer or a trading company?
We are a direct factory with over 14 years of experience in industrial filtration. Buying from us means you get factory-direct pricing and direct technical support from the people who actually build the filters.
What can be the filtration accuracy?
Filtration accuracy depends on the filter media used. For our bag filter systems, the accuracy can reach as fine as 0.5 microns.
What material options are available for highly corrosive fluids?
Beyond standard SS304/316L, we provide Fluoropolymer linings or **PPH housings** for strong acids and alkalis. To ensure chemical compatibility, we utilize Viton or PTFE seals. We can customize the material pairing based on your specific medium to ensure long-term structural integrity in reactive environments.
How is equipment safety ensured under high-temp or high-pressure?
Every housing is engineered to withstand up to 4.0 MPa and temperatures up to 260°C. The clamp quick-opening design distributes tension more evenly than traditional swing-bolts, effectively preventing thermal deformation of the sealing surface and ensuring zero-leakage operation under extreme conditions.
