AERAULIC CONNECTIONS
Connect the channels using the appropriate outlet flange. It is advisable to interpose a flexible connection
between the car and channels to not transmit the vibrations. Channels must be appropriately sized
(according to the prevalence of the machine) and insulated to prevent condensation and deaden the noise
propagation.
To connect the suction channels, you need a special accessory, the flange shooting (FRA). If you connect
the channels in another way, it is likely to compromise the accessibility of the filter or damage the machine.
