    Oxiperm 164C 4-10 kg en 11.4 Maintenance of the Suction Injector The suction injector consists of nozzle, diffuser and holder with diaphragm check valve. The sucked chlorine dioxide (ClO ) is mixed with the motive water in the diffu- ser, and transported to the disposal line. The diaphragm check valve prevents water from penetrating the PE line when the suction is switched off.
