Oil Filters

The W930 is a spin-on type oil filter, designed for diesel engines, construction machinery and agricultural machinery lubrication systems. It effectively removes metal particles, carbon deposits, sludge and fine impurities from engine oil, keeps the lubrication system clean, reduces component wear, avoids pipeline blockage, and maintains stable engine operation.

Key Features

Adopts high-performance cellulose filter media, with stable filtration accuracy and large dirt holding capacity, extending service cycle.

Built-in anti-drain back valve prevents oil backflow and avoids dry start-up after engine shutdown.

Internal bypass valve ensures normal oil supply when the filter is clogged or under cold start conditions.

Heavy-duty steel shell structure, pressure-resistant and not easy to deform, suitable for long-term harsh working conditions.

High-quality rubber sealing ring provides tight fitting performance, effectively preventing oil leakage and unfiltered oil bypass.

Standard overall structure and thread size, easy to install, perfect direct replacement without any modification.
