Air Compact 4M: 125 => 150 mm flange substitution
The Air Compact 4M can work at its maximum performance with one duct only using the size 150mm, to do
that the horizontal 125 mm flange must be dismounted and substituted with the 150mm flange supplied with
the unit. The top outlet can be closed with the supplied 120mm stopper.
In case of use with a 125 mm duct only, the unit has a 10% performance loss.
