Kit STM (MAC) = STM + MAC muffler sleeve + air inlet vent (M or ISOLA HY) + plastic adjusting sleeve + finish plate + 200mm PVC sleeve + GAE + 2 screws + installation instructions (individual cardboard packaging)
The STM silencer is made entirely from polystyrene and fits into all types of infill after making a circular hole in the wall and sealing in a Ø125mm PVC sleeve. It can be fitted either in the interior of the infill in conjunction with an
adjusting sleeve or with the removable front face exposed for inspection and maintenance.
lt is used in conjunction with an M 22, 30, or 45m³/h self-regulating air inlet 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.
Installation 1 – built in: Fit the silencer to the wall without dismantling. Make sure the sides of the SHF are lagged to ensure a thermal break. The MPR sleeve must have at least 10mm of its length inside the silencer. The STM can be installed in infills of thickness 80+10mm to 100+10mm. For deeper infills, a second adjusting sleeve will be required. Fasten the air inlet in place with screws.
Installation 2 – exposed: Cut the infill to accept the outside dimensions of the casing (minimum 160 x 500mm) using the axis of the Ø125 hole centred on the silencer as the datum. Remove the front face of the silencer. Fit two wooden strips to the wall to take the fastening screws for the STM housing (4 pre-drilled holes). When the frame is flat against the drywall, a perfect finish is obtained. The seal on the rear adapter makes the installation airtight. Fit the cover to the housing and secure with 6 screws. Fasten the air inlet in place with screws.
