Willmar Water Inc.’s recently patented AirHead controls air pumps and solenoid valves automatically by gauging the amount of air pressure in an aeration tank. The device can be used on any well system, reduces the number of cycles on the air pump and eliminates the need for a flow switch. Using a 110V household outlet and connective tubing to aeration tanks, the AirHead is easy to install and virtually maintenance-free. http://www.willmarwaterandspas.combob@willmarwater.com
