Honeywell has introduced SuperVent™, a device designed to eliminate air from hydronic heating systems without bleeding. Unlike conventional automatic air vents, SuperVent breaks up air bubbles with a patented functional principle. It features a no-clog vent assembly, a 360-degree adjustable collar ring and can be serviced in the field. SuperVent, which is part of the Honeywell Water Controls PV Series, includes a stainless steel concentrator that bursts troublesome air bubbles. A fatigue-proof spring holds SuperVent's long, horizontal lifting arm, ensuring that the no-clog baffle controls debris and prevents splashing water from entering the venting area.Honeywell.
