The Mengma Air Filter Set P640149 + P638095 is a complete primary and safety air filtration system designed specifically for heavy-duty construction machinery engines. P640149 serves as the primary (main) air filter element, responsible for the bulk filtration of incoming air. P638095 serves as the secondary (safety) filter element, providing backup protection for the engine.
This two-stage filtration system ensures that large volumes of intake air are thoroughly cleaned before entering the engine cylinder. The primary filter removes the majority of dust, sand, and airborne particles, while the safety filter acts as a final barrier - preventing contaminants from entering the engine during primary filter maintenance or in the event of primary filter damage.
The engine requires a massive amount of air during operation. If the air is not properly filtered, suspended dust and particles in the air will be drawn into the cylinder, accelerating the wear of the piston group and cylinder walls.-1In dry and sandy working environments - which are common for excavators and loaders - this problem is particularly severe. Large particles entering between the piston and cylinder can cause serious "cylinder seizure" (pull cylinder).-1Our filter set effectively prevents such issues, ensuring the engine receives sufficient, clean air for normal operation.
