The Bell & Gossett Rolairtrol® is a patented centrifugal style air separator for use in any HVAC system. Its 3-to-1 body diameter to nozzle diameter ratio slows the fluid velocity to help entrained air come out of solution, while its tangential inlet and outlet nozzles induces centrifugal fluid flow. This centrifugal flow creates a low pressure vortex in the center of the tank where entrained air can come out of solution and float to the top of the tank where it can easily be removed via an air vent or connection to an expansion tank.
