PA-DPS Differential Air Pressure Switch

Quick Overview

The PA-DPS range of differential air pressure switches are suitable for low differential pressure switching applications. These units are ideal for providing indication of fan status or filter dirty conditions in air, non-combustible, non-aggressive gases in air conditioning and ventilating installations. Adjustment ranges are available from 20 Pa up to 2,000 Pa with a max operating pressure of 5,000 Pa. The switching knob is mounted under the cover to avoid tampering and the scale is individually laser etched for high accuracy. Units are available in standard IP54 or optional IP65 housings and come complete with a Duct Fixing Kit including 2m of tubing, two pitot tubes and fixing screws.
