Standard material of construction is carbon steel with enamel coating. The unit’s filter element is cleaned by reverse jet cleaning from a compressed air accumulator. The air is directed through venturis, inducing a greater volume of air to clean the filter element for more complete dust particle dislodging. Only a single row of the filter element is pulsed at a time, leaving the remaining filter element on-line. The interval between pulsing is adjustable to ensure optimal filter element cleaning. The bin vent’s filter element is easily accessed for service through the quick access door. The air pulse cleaning of the filter element is regulated by the timer control panel. The timer allows easy adjustment of the frequency and duration of each pulse and a display shows which element row is currently being cleaned. All solenoids for pulse cleaning are located on the diaphragm valves. Each bin vent is equipped with a pressure differential indicator. The gauge measures the difference in pressure between the filter element housing and the clean air plenum, informing the operator of the effectiveness of the filter cleaning system.
