Orient Filters

We are dealing in the following kinds of pleated filters cartridges, nonworen pleated filters and membrane pleated filters.

Poly Ray Nonworen Pleated Filters
Constructed out of melt-blown polypropylene fiber media, Poly-Ray pleated filters combine exceptional solids holding capacities with precise micron ratings than depth filters. The double sheets of melt-blown media are layered to provide absolute particle retention, high solid loading and a long service life. Poly-Ray filters are also designed for membrane's pre-filtration.

Poly Fluoro Membrane Pleated Filters
The Poly-Fluoro membrane pleated filter is made of poly tetrafluoroethylene (PTFE). PTFE are characterized by high chemical inertness. The Poly-Fluoro pleated filter cartridges are widely use for filtering the strong acid and base solutions that are used in wet etching, solvent striping and cleaning manufacturing processes of semiconductor factory. The membrane has about 80-95% porosity and the uniform pore size distribution. Moreover, the filtration area of each cartridge is as high as 0.9m2 (0.67-0.8 m2 for equivalent products ofimpoI1ed brands). Therefore, Poly-Fluoro PTFE membrane pleated cartridge filters have a high flow rate, low-pressure drop and a long-life service.

Poly Nylon Membrane Pleated Filters
Poly-Nylon filter cartridges feature a naturally hydrophilic polyamide nylon membrane with a narrow pore size distribution and high porosity at the specified pore size rating. Poly-Nylon filters are suitable for the sub-micro filtration of a wide range of process liquids, in applications where the characteristics of a naturally ~1Ydrophilic membrane is required. Various grades of cartridges are used for pure water supply and fine chemicals

Poly Philic Membrane Pleated Filters
Poly-Philic pleated filter cartridge is a PES (polyethersulfone) membrane in a polypropylene casing. The filter media polyethersulfone is the mirrored asymmetric structure that ensures lower pressure drop at high flow rate and extended service life.

PES membrane has excellent chemical resistance and hydrophilization. It is widely used in BOE etchant, clean, DI water circulated filtration of semiconductor industry and photoelectric industry and the terminal fine filtration of general food and beverage factory.
