Reverse air bag systems mostly large reverse gas type fabric filters for Cement Kiln and Ferro alloys Furnace lime kilns and metallurgical processes. The Reverse Air Bag House (RABH) is a custom-built filter, designed for cleaning gases with typically high flow rates and high temperatures. 

RABH have been designed to clean emissions from various industrial processes and handle a wide range of gas volumes from 60,000 m3/hr. to more than 15,50,000 M3/hr. Depending upon the duct characteristics, BKF offers the most economical and efficient cleaning method to minimize pressure drop across the bag house. 

The typical RABH is modular in construction, the modules being set in pairs, this construction and operation of the units not only offers control on velocity profiles, but also facilitates on-line maintenance. The units - being custom built and voluminous - are dispatched knocked down to structural and panels.
