Multiquip 43839 Engine Air Filter - OEM Replacement Part

This engine air filter provides critical filtration for walk-behind power trowel engines, protecting internal components from concrete dust, debris, and abrasive particles common in finishing environments. Regular air filter replacement is essential for maintaining engine performance and preventing premature wear in high-dust concrete finishing applications.

The air filter element is designed for Multiquip PRX series walk-behind trowels operating in demanding concrete finishing conditions. Standard maintenance intervals recommend inspection every 50 hours of operation, with replacement based on operating conditions and visible contamination levels. A clogged or damaged air filter reduces engine power, increases fuel consumption, and can lead to catastrophic engine damage from dust ingestion. Operators should check the filter more frequently when working in extremely dusty environments or during heavy concrete pour schedules.

Compatible Models:

• PRX Series Walk-Behind Trowels

Regular air filter maintenance ensures optimal engine breathing, maintains proper air-fuel ratios, and extends engine service life. This OEM filter is engineered to exact Multiquip specifications for proper fitment and filtration efficiency. Genuine Multiquip OEM part, sold by an authorized dealer.
