Gas Pressure Switches:
GFS3400 Series
GFS4400 Series

The Series GFS3400 and GFS4400 pressure switches are designed for sensing pressure changes in air, natural gas and LP gas applications. These compact pressure switches sense and convert a pressure signal to an electric output. In response to a change in pressure, movement of an elastomeric diaphragm opens or closes an electrical circuit based on a predetermined set point. The Series GFS3400 and GFS4400 switches feature cost effective, snap-acting electrical contacts. Set points can be between 2.0" WC and 22.0"WC . Typical pressure connectors are 1/8" NPT (male) but other connectors can be provided upon request.

The Series GFS3400 pressure switches feature an all metal pan/bracket construction while the Series GFS4400 feature a metal bottom pan and a durable, one-piece top pan/bracket construction

All gas pressure switches are typically factory calibrated to customer specification.
