Air Vents

Calefactio automatic air vents remove trapped air to restore maximum pressure in a system. Made of brass, they can withstand temperatures as high as 120° C / 248° F (for solar air vents: 230° C / 446° F). These vents are made with a two-piece body to allow cleaning of the seat. Their side venting minimizes dirt build-up on the seat.
