Import Back Flushing Oil Filter Cartridge Zcl-I-450 — Buy in wholesale FOB from Supplier in China

The ZCL-I-450 back flushing oil filter cartridge from Dongfang Yoyik Engnieering Co., Ltd. is designed for automated reverse-flow cleaning in power generation lubrication systems, including steam turbines, coal-fired generators, and hydroelectric units. The cartridge uses multi-layer synthetic fibre media supported by a galvanised steel core, engineered to maintain continuous oil purity without system shutdown. Its back flushing capability allows accumulated contaminants to be discharged without manual cartridge replacement, reducing maintenance intervals in continuous-duty power plant environments. The design targets high dirt-holding capacity with automated cleaning cycles, though exact micron ratings and flow capacity must be confirmed with the supplier.

The filtration media consists of multiple layers of synthetic fibres, typically polypropylene or polyester, with progressively coarser layers from upstream to downstream to extend service life. The galvanised steel core provides structural rigidity against differential pressure during both normal filtration and back flush cycles. Standard cartridges in this power plant category are typically rated at 10 to 25 microns absolute, with beta ratios of 1000 or greater per ISO 4572 multi-pass test methodology. Collapse pressure ratings for steel-cored elements of this type typically exceed 5 bar. The ZCL-I-450 designation suggests a nominal flow capacity of 450 litres per minute, though this must be verified against the supplier's test data. Gasket and seal materials for oil filtration at elevated temperatures are typically nitrile rubber or fluorocarbon, depending on the lubricant type and operating temperature.

Primary applications include main lube oil systems for steam and gas turbines, boiler feed pump lubrication, generator seal oil systems, and hydro turbine governor circuits. The cartridge is also suitable for retrofitting existing filter housings where back flushing infrastructure is already installed or planned. Buyers should confirm with Dongfang Yoyik Engnieering Co., Ltd. the exact dimensions, end-cap configuration, and compatibility with specific filter vessel models. The supplier is located in Deyang, Sichuan Province, an industrial city with established power equipment manufacturing clusters. Response metrics are not available, so technical enquiries should include detailed specification requests to ensure accurate quotation.

Dongfang Yoyik Engnieering Co., Ltd. is located at 4-3F, Building A, Huashan Platz, Deyang 618000, Sichuan Province, China. The company operates within the harbour trust tier of the marketplace, with no response rate or average response time data currently available. Its specialisation is explicitly stated as manufacturing and supplying components for turbines, coal-fired generators, hydro units, electrical equipment, machinery parts, and hydraulic systems.

The supplier's product range extends beyond the ZCL-I-450 to include numerous filter elements, hydraulic filters, and water treatment components for power plant maintenance and retrofitting. No verified employee count, annual revenue, factory floor area, or client reference list is present in the source material. Buyers should request business licence verification, quality management certification, and factory audit reports before committing to volume procurement. The company's location in Deyang places it within Sichuan's industrial corridor, with logistics routes typically via Chengdu or Chongqing to Shanghai or Shenzhen ports for export shipment.
