140240 HQ-Autoair system
HQ-Autoair systems are easy to install, use and are compatible with almost every electronic dosing pump with a watermeter.
Operation: If after a certain time (programmable) there is no waterintake the HQ-AUTOAIR SYSTEM starts giving pulses to the dosing pump because of this the pump starts running. At the same time the magnetic valve opens and the liquid starts to circulate through the magnetic valve back into the container. On this way we avoid gassing in the suction tube making the dosage % perfect.
