Import Air Filter Oil Dl009001 Eh Oil Cellulose Filter — Buy in wholesale FOB from Supplier in China

The DL009001 is a cellulose-based air filter element designed for EH (electro-hydraulic) oil systems in steam turbine and generator applications. This filter uses cellulose fibre media rather than synthetic alternatives, a common construction for turbine oil breathers and vent filters where particulate exclusion and moisture control are critical. The DL009001 designation indicates a specific form factor and connection standard within Yoyik's power plant spare parts catalogue, though exact dimensional data (nominal height, outer diameter, thread specification) should be confirmed directly with the supplier against your existing filter housing.

Cellulose filter media for EH oil systems typically achieve nominal filtration ratings in the 10 to 25 micron range, with actual retention efficiency varying by manufacturer construction and pleat density. The cellulose substrate is often resin-impregnated to resist water degradation and maintain structural integrity in continuous operation at temperatures up to 80°C to 100°C. Standard industry practice for turbine oil filters includes beta ratio testing per ISO 4572 (multipass method), though the specific beta rating for this DL009001 element is not stated in the source data. End caps are generally steel or aluminium with appropriate gasket seals, and the centre tube provides collapse resistance against differential pressure.

This filter serves power generation facilities, OEM turbine maintenance crews, and EPC contractors servicing coal, gas, and nuclear steam turbine installations. EH oil systems operate at pressures typically 12 to 14 MPa with low viscosity phosphate ester fluid, making filter compatibility essential. Buyers should verify that DL009001 matches their filter housing model, as Yoyik produces numerous cross-referenced alternatives. The supplier's ISO9001 certification (2008) provides baseline quality system assurance, though specific product test reports and material certificates should be requested for each order. Packaging, MOQ, and lead time are not specified and require direct confirmation with Deyang Dongfang Yoyik Engineering.

Deyang Dongfang Yoyik Engineering Co., Ltd. operates from Huashan Plaza in Jingyang District, Deyang City, Sichuan Province, China. The supplier holds harbor-tier trust status on the platform, with a reported response rate of 0.00 percent and average response time of zero hours, indicating no active response data is currently available. The company passed ISO9001 quality system certification in 2008 and positions itself as a specialist producer and supplier of spare parts for power plant steam turbines and generators, offering both customised components and finished factory products.

The supplier's product range extends well beyond the DL009001 filter to encompass crankcase oil filters, hydraulic return filters, suction strainers, coalescer elements, and numerous cross-referenced alternatives for major turbine OEM filter numbers. The source description emphasises a quality policy of 'scientific management, continuous improvement, quality excellence, customer needs,' though no specific revenue figures, employee counts, factory floor area, or named client installations are provided. Buyers should independently verify current production capacity, export licensing, and whether the company maintains separate manufacturing or operates as a trading and engineering entity.
