Wessels Severe Service SPA Vortex type Air Separators are designed for systems that require more corrosive resistance than standard carbon steel. SPA separators eliminate air quickly and efficiently from open and closed loop heating/cooling, and potable water systems. Water enters and exits through unique "tangential" connections, which promote a low velocity swirling effect in the center of the unit. Natural centrifugal forces allow the heavier air-free water to move towards the outer edges while entrained air is captured within the “eye” of the vortex and released out the top of the separator. The water then exits near the bottom of the unit, bubble free, protecting the system against the noise, corrosion, and damage commonly caused by entrained air.
