AIRLANCO Low-Pressure Reverse Air Filters
AIRLANCO Low-Pressure Reverse Air Filters and other dust collection systems manufactured by the Nebraska firm are custom engineered for efficient, economical operation in demanding applications. AIRLANCO Reverse Air Filters are used in many such high-volume systems where dust loads are heavy. They feature an on-board direct-drive fan to save energy and maintenance costs by eliminating the need for compressed air and external blowers. A chain-drive gearmotor rotates the reverse air cleaning arm over the radially aligned filter bags inside the weathertight cylindrical enclosure. No special gearing, limit switches, or timing devices are needed. As the rotating arm moves over a row of bags, reverse airflow is directed through high-velocity nozzles on the underside of the arm into the bags so that the dust collected on their outer surfaces is released and falls into the collection hopper. Dust collection efficiency is maintained as each filter bag is cleaned during each cleaning arm revolution. An involute inlet creates cyclonic action to spin out particulates. Large particles are directed toward the collection hopper by an internal deflection cone.
