Dongfeng GX Truck Engine Parts Air Filter Assembly 1109010-H12C0

The 1109010-H12C0 Air Cleaner Assembly is an original equipment (OE) heavy-duty air filtration system designed to protect high-output diesel engines from airborne contaminants. Used on Dongfeng Tianlong GX, KL, and KX series trucks equipped with DDi11/DDi13 or Cummins Z14 engines, this two-stage air cleaner ensures clean, efficient combustion by removing dust, moisture, sand, and particulates before they enter the turbocharger and engine cylinders.

Featuring a high-strength composite housing, cyclone pre-cleaner technology, primary main filter element, and internal safety filter, it delivers exceptional filtration efficiency up to 99.98% for particles ≥0.5μm, while maintaining low pressure drop across the intake path—improving fuel economy by approximately 1–2%.

Engineered for long-haul logistics, mining, and construction applications, it operates reliably under extreme vibration, temperature cycles (-40°C to +120°C), and high-dust environments. Its integrated dust ejection valve and acoustic chamber further enhance durability and reduce operational noise.
