Galvanized Filter Bag Cage

A Galvanized Filter Bag Cage is a high-performance supporting framework for filter bags in baghouse dust collector systems.Made of premium low-carbon steel with hot-dip galvanized surface treatment,it provides outstanding rust resistance,structural stability and long service life,and is the most widely used economical filter cage in industrial dust removal projects.

Main Functions

It firmly supports the interior of filter bags,keeping them fully expanded under negative pressure during operation.It effectively prevents filter bags from collapsing,sagging or deforming,maintains maximum effective filtration area,and ensures stable airflow and continuous dust collection efficiency.

The smooth galvanized surface eliminates sharp burrs and weld flashes,greatly reduces friction and abrasion between the cage and filter bag,and prolongs the service life of filter media significantly.Meanwhile,it perfectly cooperates with pulse jet cleaning system,helping dust on filter bags to fall off easily and quickly.

Material&Surface Treatment

Base material:High-quality low carbon steel wire with good toughness and structural strength.

Surface process:Hot-dip galvanizing

The uniform zinc coating forms a dense protective layer on the whole cage surface,which offers excellent corrosion resistance,moisture resistance and oxidation resistance.It performs far better than ordinary unpainted carbon steel cages in humid,dusty and mild corrosive working environments.

Structural Features

Adopts integral spot welding process with solid connection and high overall rigidity.

Consists of vertical support wires and evenly distributed horizontal reinforcing rings.Standard longitudinal wire quantity ranges from 6 to 24.Reasonable ring spacing ensures stable shape without bulging or deformation under strong airflow impact.

Smooth welds,no burrs,no scratches on filter bags.Standard top structure,equipped with venturi mouth optionally for optimized pulse cleaning effect.Full sizes can be customized in diameter and length to adapt to various baghouse equipment.

Advantages

Excellent anti-rust and anti-corrosion performance for long-term outdoor and humid environment use.

Cost-effective and high cost performance,more economical than stainless steel filter cages.

Sturdy structure,high compressive resistance and long service life.

Easy installation,disassembly and daily maintenance.

Universal compatibility with most industrial dust collector filter bags.

Applications

Widely applied in cement plants,metallurgy,steel industry,thermal power plants,building materials,chemical industry,wood processing,boiler dust removal and other industrial air purification and dust pollution control fields.
