1109910-TK830 Air Filter Element is a high-capacity intake filter for DFL Dongfeng heavy truck air intake system. It intercepts dust, sand, pollen and road grit in incoming air, delivering clean air for combustion. This aftermarket replacement element resolves insufficient intake air, black exhaust smoke and premature cylinder liner, piston and ring abrasion caused by filter clogging, filter paper rupture and seal leakage. Effective air purification maintains correct air-fuel ratio, protects turbocharger and cylinder assembly, cutting abnormal wear risk for Dongfeng heavy trucks operating on dusty construction sites and long-distance highway freight routes.

Product Advantages High-density composite filter media features large dust holding capacity and low air flow resistance. Built-in internal support grid prevents filter deformation under suction pressure. Double sealing rubber ring avoids unfiltered air bypass. Every air filter is checked for air permeability and sealing before shipment, OEM outer contour supports simple installation during regular maintenance.

Applicable Models Compatible with Dongfeng DFL series heavy-duty commercial trucks, widely used for heavy-load hauling, engineering transport and cross-region long-haul logistics.
