Filter Cages Workmanship


1) filter bag basket is characterized by: welding firm, smooth and straight appearance 

2) its supporting ring and vertical bars evenly distributed and have enough strength and stiffness that can withstand any pressure and deformation caused by impact. 

3) dust collector filter bag cage with all joints welding firm, no loose weld or lack of weld, without welding scars, bumps and burrs. 

4) filter bag cage has light weight, smooth surface, easy to install and maintain 

5) bag filter cage has special anti-corrosive treatment based on your gas feature.


Dust Filters Capacity


Our filter cage adopts the most advanced high frequency dc multi-point welding technology for one-time welding molding, its characteristic of welding is firm, appearance is bright and clean straight, overcomes the uneven manual welding solder joint that wears the filter bag. Dust filter cage is the frame of filter bag, directly influences the quality of the working state and service life  of the filter bag. Besides, dust collector bag frame and accessories are very important for the external pulse bag filter dust collector. Perfect frame design and manufacturing can help bag filter to achieve optimal performance, and is conducive to the durability of the filter bag.


For surface treatment, we adopt imported high temperature electrostatic spraying paint baking equipment for surface treatment;


Product features: strong rigidity, size precision, surface smooth, corrosion resistance, long service life;


Our annual production capacity of 2.5 million meters, are widely used in metallurgy, chemical industry, building materials, etc, especially for the steel industry and coal-burning power plants .
