4.5 Compressed air supply
Twister evolution venturi only
⇒ Plug the compressed air tube (18) into the tube attachment on
the compressed air connection (12) as far as it will go� There will
be a slight resistance to overcome when attaching�
⇒ Select the proper coupling from the set (16, Fig� 1) provided and
install it on the other hose end to connect it to the compressed
air system�
⇒ Connect to compressed air line system�
In previous devices, the inlet filter (13) was situated outside
the device (Fig. 5-b). In these cases, push the compressed air
horse (18) onto the inlet filter (13). There will be a slight resis-
tance to overcome when attaching.
NEVER operate the device without the inlet filter!
The best vacuum performance is attained at the operating
pressure specified in the technical data (see section 9).
Use filter pressure regulator if necessary (see section
„3.3 Accessories").
The vacuum mixer is now ready for operation�
