unit as they need to be turn upside down to attach the correct
spigot on the silencer to the correct spigot on the unit.
Custom designed silencers can be attached to unit sizes 1 to 4.

ots on the other. Fit the female spigots over the male spigots on
the units and make sure that there are no gaps between the unit

spigots are extract and which are supply to the unit; make sure
that these correspond to the airflow direction of the unit
