2020AV

The Dwyer 2020AV is a Magnehelic Differential Pressure Gauge. The simple, frictionless Magnehelic gage movement indicates air or noncorrosive gas pressures—either positive, negative (vacuum) or differential. It resists shock, vibration, over-pressures and is weatherproof to IP67.

  • Dual Range: 0-20" w.c./0-17500 FPM
  • Easy-to-read for far away viewing
  • Motion damped with high viscosity silicone fluid
  • O-ring seal provides pressure tightness

  • Range in w.c./Velocity F.P.M.: 0-20" w.c./ 0-17500 FPM
  • Easy to read gage through undistorted plastic face permits viewing from far away
  • Patented design provides quick response to pressure changes means no delay in assessing critical situations
  • Durable and rugged housing and high-quality components combine to provide longservice life and minimized down-time
  • High accuracy option is twice as accurate as the standard Magnehelic gage
  • Bezel provides flange for flush mounting in panel
  • Clear plastic face is highly resistant to breakage
  • Precision litho-printed scale is accurate and easy to read
  • Red tipped pointer of heat treated aluminum tubing is easy to see and is rigidly mounted on the helix shaft
  • Pointer stops of molded rubber prevent pointer over-travel without damage
  • "Wishbone" assembly provides mounting for helix, helix bearings and pointer shaft
  • Jeweled bearings are shock-resistant mounted; provide virtually friction-free motion for helix
  • Motion damped with high viscosity silicone fluid
  • Zero adjustment screw is conveniently located in the plastic cover
  • O-ring seal provides pressure tightness
  • Helix is precision made from an alloy of high magnetic permeability
  • Calibrated range spring is flat spring steel
  • Silicone rubber diaphragm with integrally molded O-ring is supported by front and rear plates
  • Diaphragm motion is restricted to prevent damage due to overpressures
  • Die cast aluminum case is precision made and iridite-dipped
  • Overpressure Protection
  • Blowout plug to prevent your system from exceeding the ratings of any component
  • Samarium Cobalt magnet mounted at one end of range spring rotates helix without mechanical linkages.
