This page is intended for construction machinery parts dealers, rental fleet workshops and site maintenance teams. The products below are organized around job-site dust, hydraulic contamination, water in diesel, vibration and costly machine downtime, where visual matching can miss seal design, flow direction, bypass setting or hydraulic circuit requirements.
Confirm the housing before approving the air filter
Start from the machine or engine model, then match each replacement filter to its real system role. A service order may include air filtration, fuel cleanliness, water separation, lube protection or hydraulic cleanliness, so the quotation should not hide all references under one generic filter name.
