Duct pressure switches are designed to utilise differential air pressure to actuate electric switches at a pre-set actuation point. Raptor Supplies offers an array of duct pressure switches from brands like Cleveland Controls, Columbus Electric, Dwyer Instruments, Johnson Controls, Robertshaw, Siemens and Tjernlund. These switches can automatically start and stop auxiliary devices like electronic air cleaners, duct heaters, humidifiers, exhaust fans and duct booster fans. Dwyer Instruments duct pressure switches are compatible for use with vacuum and differential pressure supply and have dual scaled adjustment knobs in inch, water column and pascal units which facilitate making changes in the switching pressure without a pressure gage. The ADPS / EDPS variants are offered in settings ranging from 0.08 inch W.C. (20 Pa) to 20 inch W.C. (5000 Pa). The silicone diaphragm and PA 6.6 cobstruction of these switches make them suitable for use with air and other noncombustible gases at extreme temperatures. Johnson Controls differential air pressure switches are used to sense the flow of air in ducts. When these air pressure switches are used with electric strip heaters, they can be wired to open the circuit and de-energise the heaters when the air flow stops. These switches have a small and compact.design with easy-to-read set point scale and are available in SPST NC, SPDT, SPST and SPST NC switch types on Raptor Supplies.
