Pressure Gauges & Controls

Magnehelic® Pressure Gauges are used to measure the differential pressure between the “clean” gas side and the “dirty” gas side of the baghouse. The Photohelic® gauge is a Magnehelic gauge with the capability to allow a collector to clean-on-demand. Photohelic and Magnehelic pressure gauges can be visually checked anytime to monitor system problems.


Photohelic models combine the Magnehelic gauge with a precise pressure switch that lets you control low and high gas pressures. Knob controls adjust dual setpoints, which allow for variable deadband control. The Photohelic gauge allows for “on-demand” cleaning which not only saves you money through decreased compressed air usage, but also extends the life of your filters.


Magnehelic Pressure Gauges are the industry standard for measuring fan and blower pressures, and filter resistance, as experienced in a dust collector or baghouse.
