Versatile Family of Pulse Jet Dust Filters
AIRLANCO Pulse Jet filters have no moving parts to wear out, and come in compact, top- and side-access modular housings. The flters are available in many sizes and filter bag configurations, but the cleaning cycle is the same throughout the line: Dust-laden air or gas enters the filter through a hopper inlet where it is directed toward a deflector that slows the airflow and causes heavier particles to fall directly into the collection hopper. Lighter airborne particles follow the air stream into the dirty air housing where the filter bags are located. The particles collect on the outside surfaces of the filters. The filtered air then flows into the clean air plenum and exits the unit. The clean air plenum houses rows of pulse jet pipes lined up over the rows of filter bags. Periodic signals from a programmable timer control open valves that allow short bursts of compressed air from an external supply to flow through the pulse jet pipes and reverse the airflow in each row of bag filters in sequence. These compressed air pulses dislodge the surface dust from the filters so that it falls into the angled collection hopper, which helps funnel the dust and debris to an airlock for final disposal. Proprietary AIRLANCO venture assemblies at each bag cup draw in extra air during the pulse cycle to amplify the reverse airflow and enhance the removal of dust from the surfaces of the filter bags. These venturi assemblies increase filtration and operating efficiency. www.airlanco.com
