Import Air Hepa Filter For Clean Room — Buy in wholesale FOB from Supplier in China

Xiamen R&J Filtration Co., Ltd. manufactures HEPA filters for clean room environments with H13 and H14 efficiency grades, available in both standard and customised dimensions. Regular sizes include 305 x 305 x 69 mm, 610 x 610 x 80 mm, 1220 x 610 x 69 mm, and 610 x 610 x 292 mm. The filters serve critical air purification roles in clean rooms, fan filter units (FFU), air handling units (AHU), HVAC systems, mushroom cultivation facilities, and laminar flow hoods. Buyers source these for controlled environments where particulate contamination must be minimised to defined standards.

HEPA filters at H13 and H14 grades are constructed with pleated micro-glass fibre media sealed into rigid frames, typically aluminium or galvanised steel. H13 filters capture 99.97% of particles at 0.3 micrometres, while H14 achieves 99.995% at the same particle size under standard test conditions. The pleat depth varies with frame thickness, from 69 mm shallow-pleat designs for low-resistance applications to 292 mm deep-pleat configurations for higher dust-holding capacity. Standard industry practice uses polyurethane or gel sealants to eliminate bypass leakage. The supplier indicates custom sizing is available, which allows integration into non-standard plenum housings or retrofit projects.

Primary buyers include pharmaceutical manufacturers, semiconductor fabrication facilities, hospital pharmacy compounding units, food and beverage aseptic processing plants, and research laboratories. The filters are also deployed in mushroom cultivation where spore and contaminant control determines yield. When sourcing from Xiamen R&J Filtration, buyers should confirm the test protocol used for efficiency certification, whether MPPS or sodium flame, and request pressure drop curves at rated airflow. Packaging typically involves individual carton protection with moisture barriers; confirm with the supplier whether each filter ships with a factory test certificate.

Xiamen R&J Filtration Co., Ltd. is located at No. 52, Huli Industrial Zone, Meixi Road, Xike Street, Tongan District, Xiamen, 361100, in Fujian Province, China. The supplier holds a Harbor trust tier classification on the platform, with a response rate currently showing 0.00% and zero average response hours. This profile indicates limited or no recent engagement through platform messaging, so buyers should anticipate direct email or telephone follow-up as the more reliable communication path. The company specialises in air filtration products for controlled environments.

The listing does not state factory size, year of establishment, number of employees, annual revenue, export markets served, or specific certifications held. Buyers should verify ISO 9001 quality management status, any ISO 14644 clean room component compliance, and whether the HEPA filters carry independent test laboratory certification from bodies such as TUV, DEHS, or equivalent.
