Insufficient air source pressure: Unable to provide enough blasting force to shake off the dust.

Oil and water contained in compressed air: Oil and water will adhere to the dust, aggravate the filter bag clogging, and may damage the pulse valve.

Failure of the oil-water separator: It is necessary to regularly discharge the accumulated water in the air storage tank and water separator.

Recommendations: Ensuring a supply of dry, clean and pressure-stabilized compressed air is the key to guaranteeing the ash cleaning effect.
