The QTL-250 is a circulating oil‑pump return filter supplied by Deyang Dongfang Yoyik Engineering Co., Ltd. in China. It is listed under the product title “China Manufacturer oil filter cost QTL-250” and is intended for use in large‑scale power‑generation facilities. The supplier’s catalogue includes variants such as the DF‑LH0110R30BN/HC filter and the YWU‑160×100‑J 1 micron oil filter, indicating a family of interchangeable cartridges. All items are marketed as suitable for integration with hydraulic and lubrication circuits in thermal and hydro‑electric plants.
The filters are constructed with stainless‑steel mesh cartridges, a common material that provides resistance to corrosion and high temperature. Typical micron ratings for this class of filter range from 1 µm to 10 µm, delivering fine particle removal for engine oil and circulating water systems. Standard pressure ratings are up to 30 bar, and connection sizes are usually ½‑inch NPT, matching the inlet and outlet fittings of most industrial pumps. Such specifications align with ISO 4406‑2008 particulate cleanliness standards that many Chinese power‑plant projects adopt.
Primary buyers are EPC contractors and maintenance teams operating at sites such as the Gezhouba, Ertan and Three Gorges hydropower stations. The supplier is classified in the “harbor” trust tier, but its response rate is currently recorded as 0 percent, so direct confirmation of lead times and MOQ is advised. Trade terms, including Incoterms and payment methods, are negotiated per order and should be clarified before contract finalisation.

Before placing an order, verify the supplier’s business registration, address and the “harbor” trust tier status. Request copies of any relevant certifications, such as material or ISO compliance, and ask for recent factory photos or third‑party audit reports to confirm production capability. Clarifying these details reduces the risk of receiving non‑conforming items.
Discuss logistics early by asking the supplier to confirm the expected lead time for the QTL‑250 filter and the preferred Incoterms, such as FOB Deyang port or CIF Shanghai. Payment terms are typically negotiated per transaction; common arrangements include a 30 % advance payment with the balance payable against shipping documents. Ensure that all agreed terms are captured in a written contract before dispatch.
Arrange for pre‑shipment inspection by an independent inspection agency to verify dimensions, material, micron rating and pressure performance against the supplied data sheet. Request a full test report, including particle count and pressure drop measurements, as part of the quality documentation. Retain the inspection certificate and test results for customs clearance and future reference.
