Import Aluminum Breather Vent — Buy in wholesale FOB from Supplier in China

Richang Qiaoshan Trade Co. Ltd. supplies aluminum breather vents in one-way and two-way flow configurations for pressure equalisation across sealed industrial enclosures, hydraulic reservoirs, and storage tanks. The vents are manufactured from aluminum alloy, with the source indicating 6061 or 6063 grade or similar, giving a balance of corrosion resistance and machinability standard to marine and industrial hardware. Thread or flange mounting, exact port dimensions, and flow rate capacity are not stated in the source and should be confirmed directly with the supplier.

The one-way variant permits air escape or intake in a single direction, protecting against over-pressure or vacuum conditions depending on orientation, while the two-way variant allows bidirectional airflow to accommodate thermal cycling and fluid level changes. A typical aluminium breather vent of this class incorporates a sintered or woven media insert rated to block particulate above 10-40 micrometres and resist water ingress to IP65 or better, though the exact filtration rating and ingress protection level for this Richang Qiaoshan model are unspecified. Anodising or chromate conversion coating is standard practice for 6xxx-series aluminium exposed to outdoor or salt-air environments to prevent galvanic corrosion when mounted on steel tanks.

Primary buyers include manufacturers of hydraulic power units, transformer enclosures, agricultural sprayer tanks, electrical cabinet builders, and packaging machinery OEMs requiring maintenance-free venting. The lightweight aluminium construction suits mobile equipment where steel alternatives would add unnecessary mass. Importers should verify whether Richang Qiaoshan offers multiple thread standards, BSPP, NPT, or metric, what torque sealing method is used, and whether the vent includes a splash guard or hood for vertical mounting. Packaging is typically bulk polybag or small carton; minimum order quantities and lead time require direct enquiry.

Richang Qiaoshan Trade Co. Ltd. is registered at 4-3-103, Xinyuanxilizhongjie, Chaoyang District, Beijing 100027, China. The supplier holds harbor trust tier status with a recorded response rate of 0.00% and zero average response hours, suggesting that enquiry handling may occur through offline channels or that the profile is not actively monitored. No factory address is listed, indicating Richang Qiaoshan may operate as a trading company rather than a direct manufacturer, though this should be confirmed directly.

The company profile presents itself as a hardware supplier to machinery, automotive, electrical cabinet, and packaging sectors. Notably absent from the data are founding date, employee count, factory ownership status, named production equipment, revenue figures, client references, and any certification numbers such as ISO 9001. Buyers should therefore treat Richang Qiaoshan as an unverified trading entity until factory audit reports or supplier qualification documents are obtained, and should request material certificates for the aluminium alloy to ensure compliance with their application's mechanical and corrosion requirements.
