Description
Caleffi MINICAL series float type automatic air vent with hygroscopic cap and 1/2″ male NPT connection. Unlike standard air vent caps, hygroscopic safety cap prevents water spills in case the vent malfunctions. Simple, time tested, easy to use & install, it’s compatible with nearly any hot water heating system (baseboards, radiators, radiant floor heat, fan coils, etc.).
Removes trapped air from hydronic systems, increasing efficiency and reducing corrosion of cast iron elements (boiler heat exchanger, radiators, circulators, air scoops, etc.).
Field serviceable design allows disassembly and cleaning or basic repairs.
Made in Italy.
