Reverse-Flow: This system utilizes a fan that continuously circulates and blows air into the center of a bag, which pushes the dust off the filter bag's exterior. Each of these methods ultimately removes dust from the filter bag and guides it to being transferred to another container.

Reverse-air baghouse setups use a counter airflow to cleanse the dust from the bags. At set intervals, a fan generates a backward airflow, puffing up the bags and causing the trapped dust to drop into a collection hopper. These reverse-air configurations are commonly chosen for more extensive systems with significant dust loads. Advantages:
