Baghouse Filter Cage

A Baghouse Filter Cage(also known as a Dust Collector Cage or Filter Cage)is the essential structural skeleton for filter bags in baghouse dust extraction systems.It works in tandem with the filter media to ensure stable operation,efficient filtration,and prolonged service life.

Core Specifications

Material Options:Carbon steel,stainless steel(304/316/316L),or galvanized steel.

Common Configurations:Round shape with 6-24 longitudinal wires and horizontal support rings spaced 150-200mm apart.

Size Range:Customizable diameter(80-200mm)and length(1-6m)to match different baghouse models.

Surface Treatments:Galvanizing,powder coating,or silicone coating for corrosion and high-temperature resistance.

Main Functions

Shape Maintenance:Keeps filter bags fully expanded under negative pressure to avoid sagging,deformation,or blockage.

Wear Protection:Smooth,burr-free surface reduces friction between the cage and filter bag,extending bag life.

Filtration Enhancement:Maximizes the effective filtration area to maintain consistent airflow and dust-holding capacity.

Cleaning Support:Facilitates pulse-jet cleaning by allowing the bag to flex and release accumulated dust efficiently.

Design Features

Precision Welding:Ensures firm connections and a seamless surface to prevent bag damage.

Reinforced Structure:Multiple horizontal rings provide radial strength to resist bulging under high airflow.

Optional Accessories:Venturi nozzles at the top to boost cleaning efficiency;quick-release connections for easy installation.

Applications

Widely used in industries such as cement,steel,power generation,chemical processing,food and beverage,and waste incineration for air pollution control.
