Import Air Filter — Buy in Bulk from Supplier in China

Hongkong Kangxin Electronic Co., Ltd. offers an industrial air filter engineered to capture up to 99% of airborne particulates, including dust and contaminants critical to manufacturing and automotive environments. The filter media is constructed from high-grade synthetic or glass fibre material, providing mechanical stability and extended service intervals under continuous load. Multiple size configurations are available to accommodate standard HVAC plenums and OEM equipment mounting patterns, though buyers should confirm exact dimensional compatibility with their systems directly with the supplier.

The filter media typically achieves this efficiency through a graded density structure, with initial layers capturing larger particles and subsequent layers targeting sub-micron contaminants. Standard industry practice for industrial pleated filters employs wire-backed or plastic-framed construction to maintain pleat spacing under airflow resistance. Service life depends on pressure differential accumulation, with typical replacement triggered at 250-500 Pa above initial resistance, though Kangxin's specific recommended change-out differential should be requested. The construction appears suited to ambient temperature ranges common to commercial HVAC, typically -20°C to 70°C operating conditions for synthetic media filters.

Primary applications span pharmaceutical cleanroom pre-filtration, food processing intake protection, automotive paint booth supply air, and general manufacturing facility HVAC. Buyers in these sectors require documented filtration efficiency against ASHRAE dust spot or ISO 16890 particulate testing, and should request Kangxin's specific test protocol and classification. The supplier indicates flexible order quantities and offers FOB and CIF shipping terms. Payment arrangements including L/C and T/T are mentioned, though minimum order thresholds and standard lead times from Shanghai must be confirmed directly.

Hongkong Kangxin Electronic Co., Ltd. is registered at No.2568 Gudai Road, Shanghai 201100, China, indicating operational headquarters in mainland China despite the Hongkong company name. The supplier holds an 'imported' tier classification and 'harbor' trust level within its marketplace profile. Notably, the listing shows a 0.00% response rate with zero average response hours, which signals that prospective buyers should expect delayed or potentially absent communication through the platform messaging system.

The company profile does not disclose manufacturing ownership details, year of establishment, employee count, annual revenue, or specific client references. No factory audit certifications, quality management accreditations, or patent holdings are stated in the available data. Buyers should therefore conduct independent verification of Kangxin's production capability, quality control processes, and financial standing before committing to substantial orders. The supplier's product range appears focused on air filtration for industrial and commercial HVAC applications, though the breadth of catalogue beyond this listing is not specified.
