Reverse Air Jet Filter

A reverse pulse jet bag filter performs its function by reversing the process gas flow into the bag. This is performed by blasting a row of bags with compressed air, effectively reversing the flow of the air and removing dust from the filter bags. Most cartridge-type solutions utilize reverse jet technology. The technique is relatively simple; a jet of high-pressure air is injected into the filter element against the direction of process airflowIt is used to convey the dust that is accumulated in the bag fibers to the waste line, by discharging them to the base of the filter body via blowing, and to separate this dust again from the other particles. This way, the air to be discharged from the system will not harm the environment.For cleaning, reverse air generated by the equipment fan or medium pressure blower is directed by a rotating arm over the bags, blowing reverse air into them to remove dust. This type of reverse air baghouse generates a lower cleaning air pressure than the compressed air pulses of a pulse jet.
