High Duct Static Pressure Switch

Switch contacts are spdt with solder type connections.

High duct static pressure switch.

Series 1831 manual reset no power required dpdt low differential pressure switches which applies to hvac and high duct static cutout applications. The switch must be manually reset before the system can start again. Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans. The dwyer model 1900 5 mr manual reset pressure switch is designed to monitor duct static and shut down the blower when excess pressure occurs.

The model 1900 5 mr measures static pressure only not differential pressure. Bypass damper switch which applies to ventilation duct monitoring heat exchanger frost protection and industrial cooling circuits. Kele is the leading supplier of building automation products. Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans.

Install a duct pressure switch from grainger to help your hvac system do its job. Order the a 399 duct pressure kit separately. An air switch senses positive negative or differential air pressure and actuates an internal switch. Install a duct pressure switch from grainger to help your hvac system do its job.

The duct pressure sensors in turn send signals to crank the air handler even faster to get back up to normal operation. An air switch senses positive negative or differential air pressure and actuates an internal switch.
