Import Cleanroom Rigid High Efficiency Air Filter — Buy in Bulk from Supplier in China

The rigid high-efficiency air filter from Sincerehope Industry Co., Ltd is engineered for cleanroom applications requiring stringent air purity, capturing submicron particles to maintain ISO Class 5 to 8 environments. Its frame is constructed from galvanised steel or aluminium, with a pleated glass fibre media designed for 99.99% efficiency at 0.3 micron particles, as standard for HEPA filters in controlled environments.

The unit’s typical dimensions range from 24x24 to 48x48 inches, with depths of 6 to 12 inches, and can be supplied in custom sizes to fit specific ductwork or ceiling grids. Media is separated by aluminium or galvanised steel separators to prevent bypass, while the sealant is a flame-retardant polyurethane, standard for cleanroom-grade filters. The filter operates at a typical face velocity of 1 to 2.5 m/s, with a standard pressure drop of 250 Pa at rated flow.

Pharmaceutical, biotechnology and electronics manufacturers use these filters in HVAC systems to protect processes from airborne contaminants. Buyers source them in bulk for new cleanroom builds or retrofits, with trade terms typically FOB Shanghai. The filter’s durability in high-humidity or high-temperature conditions makes it suitable for labs and production lines where air quality directly impacts yield.

Sincerehope Industry Co., Ltd operates from Rm503, Unit1, No. 280 Long Heng Rd. in Shanghai, China, specialising in air filtration products for industrial and cleanroom applications. The company’s profile indicates it is an imported-tier supplier with a harbor trust tier, though its response rate and average response hours are currently unrecorded, suggesting buyers should verify availability directly.

The supplier focuses on high-efficiency filtration solutions, with this listing targeting cleanroom environments where particle control is critical. While the profile does not state certifications, the product’s design aligns with standard HEPA filter specifications for cleanrooms, and buyers are advised to request test reports for efficiency and pressure drop to confirm compliance with their facility’s requirements.
