Cleanroom Air Pressure Monitoring

Pressure Differential is an integral component in the maintenance of a Cleanroom.

The pressure cascades from areas of higher Cleanliness.

Cleanroom Air Pressure Monitoring

The differential is typically monitored either with the use of a guage such as a Dwyer Magnehelic.

To monitor the pressure differentials we typically recommend either the SETRA SRPM or SRDM which include a visual and audible indication of pressures under the minimum setpoint.

These systems require a time delay, as the pressures will equalize between the two rooms anybtime a door opens, so a minimum time differential must be part of any SOP.

These units can then be monitored by the Building or Facility Management System, or by a CFR 21 Part 11 monitoring system.
