Caleffi automatic air vent

Caleffi’s DISCALAIR is a high-discharge, high-performance, automatic air vent. It has a pin-guided float for reliability in not-so-perfect vertical installations. It is 100% serviceable; the internal float/vent assembly can be replaced if it should ever become damaged. Vent cap choices offer additional flexibility. High-venting capacity of 1.8 SCFM at 20 psi and 3 SCFM at 50 psi, with 1/2” FNPT connection make it right for medium-to-large installations. Also, the auto air vent can be used with Caleffi ThermoCon storage tanks.
