从China供应商批发进口Air Purifier Br110 Breather Filter — FOB条款

The BR110 breather filter is a desiccant air purifier designed for integration into power generation and heavy industrial hydraulic systems, manufactured by Deyang Dongfang Yoyik Engineering Co., Ltd. in Deyang, Sichuan Province, China. The unit functions as a moisture and particulate barrier on fluid reservoir vents, preventing atmospheric contamination from degrading oil dielectric strength or accelerating oxidation in turbine lube oil and transformer systems. The BR110 designation indicates a specific model within Yoyik's broader filtration catalogue, which includes duplex cartridge filters, cellulose filter elements, and oil purifier separation stages for thermal and hydroelectric plant applications.

Breather filters of this class typically employ silica gel or molecular sieve desiccant media with a nominal particle retention rating of 3 to 10 micrometres on the air intake path, though the exact mesh specification for the BR110 is not stated in the source data. The housing is generally fabricated from carbon steel with an epoxy powder coating to resist the sulphurous atmospheric conditions common near coal-fired stations, with threaded or flanged connections conforming to Chinese standard GB/T or international ISO 228-1 pipe thread forms. The desiccant charge changes colour from blue to pink (indicating cobalt chloride or equivalent indicator saturation) when moisture capacity is exhausted, providing a visual maintenance trigger without continuous instrumentation.

Yoyik's product line serves power plant operators, original equipment manufacturers of steam turbines and gas turbines, and aftermarket maintenance contractors across Asia, Africa, and the Middle East. The BR110 breather filter is typically replaced on condition-based or time-based schedules aligned with turbine overhaul cycles, with desiccant saturation rate dependent on local humidity, reservoir breathing frequency due to thermal cycling, and the presence of external contamination sources such as coal dust or cooling tower drift. Buyers should confirm with Deyang Dongfang Yoyik Engineering whether the BR110 is supplied with replacement desiccant cartridges or as a fully disposable assembly, and whether the unit includes a pressure relief bypass or vacuum breaker to prevent reservoir deformation during rapid fluid level changes.

Deyang Dongfang Yoyik Engineering Co., Ltd. is headquartered at Huashan Plaza in Jingyang District, Deyang City, Sichuan Province, China, a region with established concentrations of heavy electrical equipment manufacturing and nuclear power research infrastructure. The company operates under a trust tier classification of harbor and maintains a response rate of 0.00 percent with zero average response hours, indicating that direct communication may require persistence or engagement through alternative channels such as trade fair meetings or intermediary agents. The supplier's stated strategic focus encompasses both traditional power generation equipment optimisation and new energy system component development.

The supplier profile does not disclose year of establishment, registered capital, annual revenue, factory floor area, employee headcount, ISO 9001 or ASME quality system certifications, or named client installations. Yoyik's product range extends beyond breather filters to hydraulic filter elements, oil purifier machines, and control cabinet ventilation systems, suggesting vertical integration within fluid power and thermal management categories. Buyers should independently verify business registration through the Sichuan Provincial Administration for Market Regulation and request references from existing power plant end-users before committing to contract values that would warrant a factory acceptance test or source inspection visit to Deyang.
