Install a duct pressure switch from Grainger to help your HVAC system do its job. An air switch senses positive, negative or differential air pressure and actuates an internal switch. Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners, duct heaters, humidifiers, exhaust fans and duct booster fans. Rely on Grainger for a wide range of duct pressure switch options.
