80mm diameter NON-RETURN AIR valve for flexible and rigid hot and cold air pipes

 AIR NON-RETURN valve Ø 80 mm

for Hot and Cold Air

CHARACTERISTICS:

AIR NON-RETURN valve, diameter 80 mm, ideal for installation in rigid or flexible pipes. It will prevent the return flow of cold air or odors.

The item is easy to install as there is no need to cut the pipe, just insert it and make it adhere inside the pipe itself.

Non-return valves are installed in ventilation systems that operate punctually or intermittently (e.g. kitchen extractor hoods or forced ventilation ducts).

Furthermore, they prevent air from leaking into the room from the outside. If the system shuts down (forced ventilation is switched on), the shutter closes mechanically with a spring inserted inside the unit itself.

The material is galvanized sheet metal, therefore ideal for installation on hot and cold air production circuits and forced extraction.

NB: the item is not suitable for installation inside the SMOKE exhaust pipes of: boilers, water heaters and stoves.
