PP High Flow Filter Cartridge For Pharmaceutical Water
Prefiltration 5μM 40"
Description of Pharmaceutical water prefiltration
WECHANG high flow filter cartridge are coreless, single open-ended
filters that offer high filtration efficiency. These filters have a
large diameter and laid over pleated cartridge with an
inside-to-outside flow pattern that prevents debris from escaping
the filter. The high flow rate at 1900 lpm or 500 gpm for a 60-inch
length element allows for fewer cartridge change-outs.
Application of Pharmaceutical water prefiltration
- CMP Filtration;
- Liquid prefiltration;
- Sewage filtration;
- Security filtration;
- Clarification filtration.
Features of Pharmaceutical water prefiltration
- Easy to install, saving, less filter element replacement, help
customers save labor costs;
- Filtration efficiency up to 99.8%.
- Made entirely of polypropylene material, without any adhesives, and
with low leaching;
- Large area filtration with high throughput;
- Core free structure;
- Inside-to-outside flow pattern that traps contaminant inside the
element, thus preventing polluting the treated water during the
cartridge change-out;
- High flow rate & long life;
- High pollution tolerance.
- 100,000-level clean room manufactured;
- 100% integrity test for every filter cartridge before delivery.

General Description of Pharmaceutical water prefiltration :
WechanFIB ultra large flow filter is a large-diameter, non center
rod, single opening filter with a unique design of inward and
outward flow direction, with a filtration area of up to 6m ²/20
inches. At a flow rate of 40 inches, it can reach over 60t/h,
achieving high flux and long lifespan. Using PP membrane material
and unique multi-layer nanofiber folding technology, a gradient
filtration structure is achieved, increasing the space for
pollutant absorption and greatly extending the service life,
thereby reducing replacement frequency and system costs.
