Expanflex ESPA Vortex type Air Separators eliminate air quickly and efficiently from open and closed loop heating/cooling 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 of 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.
