Differential pressure is the difference in pressure in a dust collector from the “dirty side” to the “clean side.” Changes are typically an indication of changes in the condition of the filters bags, such as a bag leak or rupture, or an indication that the cleaning system is not functioning properly.
Differential pressure is measured using a variety of pressure gauges, such as U-Tube Manometers, Magnehelic® gauges and Photohelic® gauges, all of which Southern Filter Media (SFM) stocks for its OEM baghouse partners and their customers.
The Magnehelic Pressure Gauge measures differential pressure whereas the Photohelic Gauge measures the differential pressure and provides the capability for “on-demand” cleaning in conjunction with a timer board; timers are also available with built-in pressure switch and differential pressure readout.
On-demand cleaning based on differential pressure has a variety of benefits including compressed air savings, longer life on solenoids and diaphragm valves, and extending the life of your filter bags.
