FOAMJET TM 12E- Digital direct injection foam proportioning system is used to maintain selected constant foam-water proportion regardless of water flow fluctuations. The system accurately delivers foam concentrate from 0.1 % to 8 % through a check valve / injector fitting, directly into the water discharge stream. The system uses high quality industrial components. Digital direct injection foam proportioner uses electrically driven foam pump. The pump and motor drive are designed for long-term load with over temperature and over current protection. For top performance the maintenance free brushless motor is used. Fast selection with rotary encoder knob is suitable for easy percentage setting.
