Caleffi R59119 Discal Air Vent Cap

The Caleffi R59119 Discal Air Vent Cap is a replacement component used on automatic air separators within commercial systems. where it support to control the release of trapped air from closed-loop heating and cooling circuits in HVAC systems. In operation, the cap works with the internal vent mechanism to allow accumulated air to escape while supporting stable circulation and reducing noise or inefficiency caused by air pockets. It is used in clean systems such as radiator networks, chilled water loops, and heat pump connection, where it works as a service part in maintaining continuous air separation performance within the system assembly.
