The pulse of dust collectors - Plant Services

Dec 10, 2013· Observe the pressure gauge when the pulser hits. If the pressure drop is too high (more than 10-20 psig), start looking for the cause. Record the specifications on the dust collector (cfm per pulse, feed line pressure, time per pulse, cycle time between pulses). Calculate the rate of flow, and check line size and storage.
