Dwyer 2002 Magnehelic® Differential Pressure Air Filter Gauge, 0 to 2" WC

Dwyer 2002 Magnehelic® Differential Pressure Air Filter Gauge, 0 to 2" WC

Control the Critical with the Series 2000 Magnehelic®

Designed in the USA and time-tested in critical locations around the world, the authentic Magnehelic® differential pressure gauge is used in applications including filter status monitoring, duct or building pressure, and clean room pressure indication.

The Magnehelic® gauge consists of two pressure-tight compartments separated by a flexible diaphragm. The interior of the case serves as the high-pressure side, while a sealed chamber behind the diaphragm serves as the low-pressure side. Differences in pressure cause the diaphragm to move, and its motion is transmitted to the pointer. The gauge requires no maintenance, with only occasional zero adjustment performed by opening the plastic vent valves and turning the pointer adjustment.

Applications for Use

• Filter status monitoring in air handler units

  Dwyer's Magnehelic® gauge allows for a quick visual status check of the pressure across filters. A significant pressure difference across the filter can be a sign that there is decreased air flow. Monitoring the differential pressure will help to indicate when filter replacement is needed, or if damper blockages and malfunctions are present.

• Filter monitoring in dust collectors

  Over time, dust accumulates on the filter of dust collectors, so periodic cleaning is important to maintain continuous operation. When the pressure drop indicates that cleaning is necessary, a timer controller is manually activated to initiate a cleaning cycle which involves solenoid valves releasing pulses of air.

• Pressure monitoring of scrubber & fume exhaust systems

  Dwyer's Magnehelic® gauge monitors pressure within fab/subfab scrubbers and fume exhaust systems. Visual status informs the system owner of real-time negative and positive pressures. It also assists with balancing system laterals and mains throughout the fab/subfab facilities.

• Room pressure monitoring for hospital isolation rooms

  The Magnehelic® gauge is used in hospitals all over the world. When an isolation room is kept at a negative pressure in relation to the anteroom, air from the anteroom will be pulled into the isolation room. This negative pressure relation will prevent pathogens from escaping as no air can leave the isolation room.
