Cut-out Ø125 mm



The SRT+ silencer is made entirely from sheet steel and fits into all types of infill after making a circular hole in the wall and sealing in a Ø125mm PVC sleeve. It is fitted in the interior of the infill in conjunction with an adjusting sleeve. 

Model SRT+ 30/57 is used in conjunction with an ISOLA 2 self-regulating air inlet with (flow rating 22 or 30 m³/h).

Model SRT+ 45/54 is used in conjunction with an ISOLA 2 self-regulating air inlet (flow rating 45m³/h) or an ISOLA HY humidity controlled air inlet.

Make a hole in the wall and seal in a Ø125mm PVC sleeve sloping slightly toward the exterior.

Outside, once the sealing is complete, clip on the louvre grille.

Fit the silencer to the wall with the 2 fastening lugs on the sides.

 

Make sure the sides of the SRT+ are lagged to ensure a thermal break.

The MPR sleeve must have at least 10mm of its length inside the silencer. The SRT+ can be installed in infills of thickness 80+10mm to 100+10mm. For deeper infills, a second adjusting sleeve will be required.
