Dustless dosing system for for dosing active coal (PAC). Active coal is dosed to remove organic impurities from water, such as bound chlorine.

System delivers active coal to the filtration tank by creating a weak vacuum on the dosing screw – we recommend placing the injection point before the filter pump. This dosing system is suitable to be installed in public pools with multiple filtration circuits and to use the distribution system. The water supply can be used from
a recirculation system or water connection from the order.
