1.4 IDA In-Line Deflagration Arrester Certification
The IDA certification is optional. Contact Imperial
Systems to verify if your CMAXX is equipped with the
IDA certification.
The CMAXX using the Proprietary DELTAMAXX IDA
Filters is proven to completely isolate flame transmission
and stop combustion from passing through the filters.
With IDA you can safely return air back into the workplace.

In the event of a deflagration the following must be
performed before the unit is returned to service.

and filters will seal against it properly.
