What is a Dust Collector Bag Cage?
A Dust Collector Bag Cage is basically also known as a filter bag cage, dust catcher cage, or baghouse cage that is a crucial supporting framework designed to hold and stabilize filter bags inside industrial baghouse dust collectors.
It acts as the structural skeleton of the filter bag which is ensuring that the filter media maintains its shape and integrity during the filtration and cleaning process.
Manufactured by Hebei OuTai Environmental Protection Equipment Co., Ltd. (Senotay), our dust collector cages are crafted with high precision and durability that is basicallly ensuring optimal performance in heavy-duty industrial environments such as power plants, steel factories, cement plants and chemical industries.

Features of Dust Collector Bag Cage
Structure: bag cage usually consists of header cover, protective sleeve, frame longitudinal inner bar, frame longitudinal outer bar and bottom cover, etc. It has different structural forms such as multi-section type, ventilator or protection short tube, down-unloading type, plug-in type and chuck type.
Characteristics: The bag cage has enough strength and rigidity to withstand the gas pressure of the filter bag in the state of filtration and soot removal, and prevent deformation during transport and installation.
Surface Treatment:
The surface treatment includes galvanisation, plastic spraying, organosilicon spraying, etc. to enhance the corrosion resistance, acid and alkali resistance of the bag cage and prolong the service life.
Specification and shape:
Specification: The diameter of bag cage is usually between 100cm and 200cm, and can be customised according to customer requirements.
Shape: Common shapes include round, trapezoidal, oval, pleated, flat, rhombic envelope type, multi-section type, and so on.
Application areas:
Dust collector bag cage is widely used in electric power, iron and steel, chemical industry, coking, coal mining, non-ferrous smelting and other industries for dust removal treatment of various industrial exhaust gases.
Use life:
Under normal use and maintenance conditions, the service life of dust collector bag cage is generally up to more than 3 years.
In short, the dust collector bag cage is an indispensable accessory in the bag filter, and its quality directly affects the dust removal effect and the service life of the filter bag.
