The Coral IPERJET DF is designed so that incoming air enters the top of the unit and travels down the back side, the contaminated air then makes a 180˚ turn and travels straight up into the filter chamber. Due to the rapid change in direction, any heavy solids fall out of the air stream and are deposited into a first stage collection bin located at the back of the unit.

Contaminated air then passes through our specially designed high efficiency filter cartridges where 99% of the harmful solids are removed.

The Coral electronically controlled pneumatic back pulse system keeps our high efficiency filter cartridges operating at peak efficiency. The controller constantly monitors the condition of the filter cartridges by using differential pressure, always checking the inlet pressure against the outlet pressure. Once the controller detects that the filter cartridges are clogging, a cleaning cycle is initiated. During the cleaning cycle, high pressure compressed air (7 bar – 101 psi) is released inside the filter cartridges creating a shock wave that forcibly pushes the collected solids off the cartridges. The solids fall by gravity to a second lower collection bin for removal.

The Coral high-performance fan mounted on the top of the IPERJET DF assures a high suction capacity and quiet operation.
