Description
DESCRIPTION:
Air/flue gas pressure switch interchangeable with all versions applied to gas boilers and pellet stoves; supplied with metal fixing bracket. Of robust construction, and high precision and reliability they are used to detect differential air pressure. Inside the polycarbonate housing there is a detection diaphragm that activates a contact when the pressure differential applied to the two nozzles reaches the upper setting value (trip) and restores it when it falls below the lower setting value (release).
