External wall grille GAPM 125more information

Cut-out Ø125 mm

The SC silencer comprising a muffler sleeve in conjunction with a self-regulating or humidity controlled air inlet (circular connection) fits into all types of infill after making a round opening in the wall and sealing in a Ø125mm sheet steel sleeve.

The assembly comprising the SC silencer, the GAPM outer wall grille, and the EM HY humidity controlled air inlet or EM A 22/EM A 30 self-regulating air inlet can be fitted equally well into externally or internally insulated walls.

Make a hole in the wall and seal in a steel sleeve (max ID Ø125, min ID Ø120) sloping slightly toward the exterior. Outside, once the sealing filler is complete, screw the GAPM 125 grille adapter in place and clip the grille to it.

Fit the Ø125 muffler sleeve into the Ø125 duct. Plug the air inlet into the duct.
