Imperial Systems, Inc. (Jackson Center, PA) has tested the CMAXX Dust Collector with IDA DeltaMAXX Filters and found that in all tests, the filters could isolate a deflagration and stop a flame front. Without any trace of flame or spark transmission downstream of the IDA filters or in the clean air plenum, the CMAXX is officially certified to be IDA compliant. Using a CMAXX without explosion venting, the IDA DeltaMAXX Filters contained a flame front with pressures beyond 4 PSI and a deflagration of 185 KST using corn starch. Additionally, the unit's body was tested to withstand a deflagration of corn starch at 185 KST with pressures exceeding 4 PSI. The entire explosion diverted through the IDA DeltaMAXX Filters, which showed no sign of deformation. The internal cages of the filters remained in perfect shape and the seals did not deform or melt whatsoever.
