Import Chemical Filter — Buy in Bulk from Supplier in China

The Chemical Filter from Wuxi Dongquan Industrial Equipment Technology Co., Ltd. is designed for pre-filtration in high-precision industrial environments, including semiconductor manufacturing and micro-electronics assembly. It is constructed with synthetic media capable of capturing particles down to 0.3 microns, with standard filtration efficiency ratings aligned with ISO 16890 Class ePM1. The filter housing is made from corrosion-resistant polycarbonate, rated for operating temperatures up to 80°C and pressures up to 10 bar.

Typical media compositions include layered melt-blown polypropylene and glass fiber, consistent with industry standards for cleanroom applications. The frame is sealed with polyurethane adhesive to prevent bypass leakage, a common requirement in Class 1000 cleanrooms. Variants are available in standard dimensions of 200mm x 200mm x 100mm and 300mm x 300mm x 150mm, with custom sizes offered upon request. The product is not certified to ISO 14644 but is engineered to meet the particulate retention demands of that standard.

This filter is purchased primarily by semiconductor fabs, electronics contract manufacturers, and automotive OEMs requiring contamination control in assembly lines. Buyers typically order in batches of 50 to 500 units, depending on production volume. Packaging is in single-wall corrugated boxes with internal foam inserts, shipped under FOB or CIF terms. Lead time is typically 15 to 25 days after order confirmation, subject to material availability and customization.
