Spring Filter Bag Cages

Spring Filter Bag Cages(also known as spring bag cages or spring filter cages)are flexible,telescopic supporting structures for filter bags in baghouse dust collectors.

Core Features

High Elasticity&Flexibility:Made from coiled steel wire(typically 5mm diameter),they can compress and stretch freely.This absorbs vibrations,thermal expansion,and repeated pulse-jet cleaning shocks.

Space-Saving Design:Compact when compressed for easy transport and storage.Ideal for installations with limited headroom.

Easy Installation&Maintenance:Simply compress,insert into the filter bag,and release to expand.No precise alignment needed.

Longer Bag Life:Uniform support and shock absorption reduce abrasion,extending filter bag life by 20-30%compared to rigid cages.

Corrosion Resistance:Available with surface treatments like galvanizing,epoxy spray,or organic silicon coating for different temperatures and environments.

Materials&Specifications

Materials:High-quality low-carbon steel,galvanized steel,or stainless steel(304/316).

Standard Diameter:Generally≤130 mm.

Standard Lengths:1.5m,2m,2.5m(customizable).

Types:With or without a venturi tube.

Applications

Widely used in industries like metallurgy,cement,power generation,chemicals,food,and waste incineration,primarily in pulse-jet dust collectors.
