Cut-out Ø125 mm


The SRT made entirely from sheet steel fits into all types of infill after making a 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 30/54 is used in conjunction with an M-G 22 or 30m³/h self-regulating air inlet.

Model SRT 45/51 is used in conjunction with an M-G 45m³/h self-regulating air inlet or an AIRA 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, fit 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 SRT. Can be installed in infills of thickness 90+10mm to 110+10mm. For deeper infills a second adjusting sleeve will be required.
