BG model R-2-1/2N is a 2-1/2" threaded Rolairtrol air seperator with strainer. 115 gpm capacity, cast iron body rated 125 psi and 350 degree F. Shipping weight 90lbs, ASME construction.
Removal of air from within the water will increase heat transfer, save energy and increase heating comfort. When the fluid enters the seperator, a combination of centrifugal force and velocity reduction of the fluid though the baffle will cause the air to be collected in a stainless steel tube. The air then rises to an air vent. The deaerated water then continues though the system.
