Specification

Description

This engine air filter with part number 528-0585 (5280585) is specially designed for the engines of 450F, 420F, 430F series construction machinery. As a core filter component of the engine air intake system, it adopts an integrated oval housing structure with high-density professional filter paper. Produced with precise original-size molding, it can perfectly fit the original air filter assembly mounting position and directly replace the old filter element without any modification. Widely applied to construction machinery such as loaders and excavators, it purifies intake air efficiently to create a clean air supply environment for engines.

Advantage

The high-precision integrally molded sealed housing fits tightly with the air filter housing to prevent unfiltered air and dust leakage, which avoids wear of engine cylinders caused by bypass pollutants.
The thickened filter paper with high dust holding capacity greatly extends the service cycle of the filter element, cutting down frequent maintenance labor and spare parts costs.
Standardized dimensional production based on original equipment data ensures easy installation and disassembly, perfectly matching all original buckles and fixing positions for quick replacement.
Temperature-resistant and moisture-proof raw materials enable stable performance under harsh working conditions including heavy dust, high temperature and rainy construction sites, preventing filter paper deformation and shell cracking.
Graded air intake filter structure keeps stable air intake resistance, avoiding rapid resistance rise caused by clogging and guaranteeing steady power output of construction equipment.

Performance

High-efficiency Filtration: It intercepts dust, silt, fine gravel and other particulate impurities with micron-level filtration accuracy, effectively protecting engine core parts like pistons, cylinder liners and turbochargers from abrasion and extending the overall service life of the engine.
Stable Air Intake Efficiency: Optimized pleated filter paper design balances high filtration efficiency and low air intake resistance, ensuring sufficient air supply for the engine to prevent power drop, excessive fuel consumption and excessive black exhaust emission.
Long Service Durability: The solidified waterproof and oil-proof filter paper features strong tear resistance and large dust storage capacity, maintaining stable filtering performance even in heavy-dust construction environments and reducing unexpected equipment downtime.
Excellent Sealing Performance: The integrated elastic sealing structure maintains tight sealing under continuous vibration and bumpy working conditions, completely eliminating engine wear risks from short-circuited unfiltered air intake.
