EL-AV EFDPG Differential Pressure Gauge for EF Series Filter Housings

Snap-in differential pressure gauge for any EL-AV EF Series compressed air filter housing. The color-coded green / yellow / red dial gives an at-a-glance read on element loading — swap the cartridge when the needle enters the red zone to avoid energy-wasting pressure drop across a clogged element.

• Color-zone dial: green (clean) · yellow (service soon) · red (replace now)
• Threaded inline mount — no external piping
• Rated to 16 bar / 232 PSI
