The HLX-7909AB air filter kit includes both an outer (primary) filter and an inner (safety) filter, working together to provide exceptional protection for the engine. The outer filter effectively captures larger airborne particles such as dust and debris, preventing them from entering the engine system. Meanwhile, the inner filter acts as a secondary defense, further capturing residual contaminants in case the outer filter is damaged or clogged, ensuring clean air intake.This filter kit is suitable for a wide range of construction machinery and heavy-duty equipment. It is compatible with various mainstream models and is especially ideal for high-dust, high-intensity working environments. It delivers reliable air filtration for engines, improves combustion efficiency, and helps extend equipment service life.
