Features of the SANICIP bag filter include an increased cylinder diameter to reduce the wear rate due to sandblasting and rubbing and a redesigned air inlet to reduce the risk of powder deposits forming. Super-sonic nozzles are used for reverse jet pulsing instead of reverse jet nozzles and the clean air plenum has been redesigned to be easier to clean in place. The top covers weigh less to make them easier to remove for routine servicing and the system now includes new sanitary explosion vent panels.
