7.2 Changing the Blow-Off Flow Rate on the Ejector
Do not overwind the stop on the valve screw. A minimum flow rate of approx. 15 % is always
necessary for technical reasons. The blow-off volume flow can be set between 15 % and
100 %.
There is a valve screw below the vacuum connection that can be used to adjust the blow-off flow rate.
The valve screw is equipped with a stop on both sides.
