A ComboFilter is a combination of an Electrostatic Precipitator (ESP) and a Bag House (BH) offering an advantage of agglomeration of particulate matter through electrostatic precipitation and further reduction of emission through the usage of filter media. ComboFilter is the ultimate solution to comply with the revised stringent emission norms by retrofitting few fields of the ESP to BH. Clients benefit with system augmentation in terms of cost saving (CAPEX), overcoming issues pertaining to lower pressure drop across the system, amongst many other distinctive advantages.
