Premium Filter Media: Excellent dust‑holding capacity, moisture‑resistant, anti‑deformation under dusty, humid construction‑site working conditions. High filtration efficiency captures fine dust, sand and airborne particles to protect engine cylinders, pistons and turbo components from abrasive wear.
Precision Sealing Structure: High‑quality elastomer sealing gasket ensures tight installation without air leakage. Prevent unfiltered dirty air bypassing the filter element and damaging your engine system.
Optimized Pleat Design: Reasonable folding structure keeps balanced airflow, low intake resistance. Guarantees sufficient air supply for engine combustion, maintains stable power output and helps improve fuel economy under heavy‑load operation.
Rugged Integrated Frame: Reinforced plastic support frame resists negative‑pressure collapse, shock and vibration on job sites. 100% dimension‑checked, no modification required for installation. Fast and simple filter element swap during regular maintenance.
Extend engine service life, cut down unexpected repair cost for your backhoe loader.
