Core Components
A Top-mounted dust filter element consists of four essential structural parts:
Filter Media: it Captures airborne dust and fine particles.
Skeleton Support Frame:filter Ensures stability and resists airflow deformation.
End Caps (Top & Bottom): Designed for quick mounting and sealing.
Sealing Gasket: Prevents leakage between filter housing and cartridge edge.
How It Works: The Working Mechanism
Air Inlet Stage: Dust-laden air enters the dust collector chamber from the working area.
Filtration Stage: The air passes through the pleated filter media. Solid particles are trapped on the surface, while clean air flows through.
Dust Accumulation: Particles accumulate on the outside of the cartridge, forming a dust cake that improves filtration efficiency.
Cleaning Cycle: Periodic reverse pulse or compressed air jet removes accumulated dust from the surface.
Clean Air Output: Filtered, purified air is released back into the environment or recirculated in the system.
Main Features of Top-Mounted Dust Filter Element
Top Entry Design: Allows rapid installation and replacement without dismantling the whole system.
High Filtration Precision: Captures fine particles as small as 0.3 microns.
