• longer bag service life
• increase the air volume of existing dust collectors to increase production capacity
• lower emission
• reduce energy consuption
• reduce operation cost
• reduce pressure drop
• lower pulse jet pressure and frequence
• small bag house and building area
• lower the filter velocity

Our standard pack for cage is steel crate which is made of tube steel and laid steel plate at the crate bottom. The crate width does not excess 1140mm, so crate can be loaded in two pieces per the width of container, and the height of crate is subjected to the cage quantity and type of container. We seal the opening when cage put in. This kind of crate design can well protect cage and endure a long distance and time transportion.
