Import Air Filter Br110 Eh Oil Tank Breather Filter — Buy in wholesale FOB from Supplier in China

The BR110 EH Oil Tank Breather Filter is a cellulose-element air breather designed for electro-hydraulic (EH) oil systems in power generation equipment. Manufactured by Deyang Dongfang Yoyik Engineering Co., Ltd. in Sichuan Province, this filter maintains tank headspace cleanliness by preventing particulate ingress during thermal breathing cycles. The BR110 designation indicates a specific form factor compatible with standard EH oil reservoir mounting configurations. The filter employs a cellulose media construction, typical for this application, providing efficient capture of atmospheric dust and moisture before contamination reaches the servo-quality phosphate-ester fluid.

Cellulose filter media in EH breather applications typically achieve absolute filtration ratings in the 10 to 40 micrometre range, with the BR110 conforming to industry-standard dimensions for direct replacement in Dongfang turbine auxiliary systems. The element construction uses pleated cellulose paper supported by wire mesh, bonded to metal end caps with nitrile or similar elastomeric seals. Operating temperature limits for standard cellulose breathers in this class generally span -20 degrees C to 80 degrees C, though the buyer should confirm the exact thermal rating and compatibility with synthetic ester fluids if the system uses non-standard fill. The supplier lists this item among a portfolio of over twenty filter and strainer products for power plant rotating machinery.

Primary buyers for the BR110 include power plant maintenance departments, OEM aftermarket procurement teams, and hydraulic system rebuilders serving the thermal power sector in China and export markets. The filter serves critical applications in steam turbine EH control oil systems, where particulate contamination directly impacts servo-valve performance and turbine protection logic. Sourcing considerations include verifying the thread or flange interface dimensions against the existing tank neck, confirming the cellulose media is rated for the specific oil type, and establishing whether the supplier provides batch test certificates for beta-ratio validation. The buyer should request material certification and pressure-temperature ratings before finalising specifications.

Deyang Dongfang Yoyik Engineering Co., Ltd. operates from Huashan Plaza in Jingyang District, Deyang City, Sichuan Province, with postal code 618000. The company holds a Harbor trust tier designation on the marketplace, with a response rate of 0.00 percent and no recorded average response hours, indicating limited active engagement or a dormant communication channel. The supplier profile describes itself as a comprehensive enterprise integrating research and development, manufacturing, and sales, with emphasis on power plant equipment procurement and technical services. The listing does not disclose employee count, annual revenue, factory floor space, or specific quality management certifications such as ISO 9001.

The supplier's product catalogue spans hydraulic filters, oil strainers, filter cartridges, and regeneration device elements for power station applications, with particular concentration on Dongfang turbine auxiliary systems. The source description references an experienced technical team and complete after-sales service system, though no third-party verification of these claims is cited. The company positions itself for both large-scale power station construction and small-scale equipment retrofit projects. Buyers should independently verify production capacity, quality control procedures, and certification status before committing to volume orders, as the profile lacks specific accreditation details or client references.
