low pressure nozzle
Suttner chemical suction sets
The operation of the injector depends on:
1 The nozzle type must be chosen in
dependence on the output of the high
pressure cleaner.
2 The difference of pressure allows addition
of chemical products occurred by special
effect of "venturi" nozzle. This effect is given
when the water also rinses through the low
pressure nozzle. This has a bigger orifice
than the high pressure nozzle and is
