Optional Equipment
Magnehelic
®
Gauge
The Magnehelic is a differential pressure gauge used to
measure the pressure difference between the clean and
ambient air and provides a visual display of filter change
requirements. The low-pressure tap is located in the
clean-air plenum located on the back of the cabinet.
1. Choose a convenient, accessible location on or near
the unit for mounting that provides the best visual
advantage.
2. Plug the pressure ports on the back of the gauge
using the two supplied 1/8-in NPT pipe plugs. Install
one 1/8-in NPT male adapter, also supplied with the
gauge, into the low-pressure port on the side of the
gauge. Attach the mounting bracket using three
#6-32 x 1/4-in screws supplied.
3. Mount the gauge and bracket assembly to the
supporting structure using three self-drilling screws.
4. Zero and maintain the gauge as directed in the
manufacturer’s Operating and Maintenance
Instructions provided.
