Cut-out Ø100, Ø125 mm



In the scope of an ALIZÉ III humidity controlled ventilation system (Technical Appraisal 14/13-1910), EM HY air inlets are used in conjunction with the system’s humidity controlled or timed extraction vents.
They are characterized by a flowrate varying from 6–45 m³/hour (at 20Pa pressure head) in line with the room’s humidity variations.
The EM HY humidity controlled acoustic air inlet (Ø100 or 125mm), installed on the indoor

side, is made from white polystyrene. For installation in main rooms (living and bedroom) to supply air renewal in humidity controlled, single flowrate forced ventilation systems.
The GAP external wall grille is made from UV- and weather-resistant white polystyrene .

Make a hole in the wall and seal in a steel sleeve Ø125mm (max ID Ø125, min ID Ø120) or Ø100mm (max ID Ø100, min ID Ø97) sloping slightly toward the exterior. Once the sealing is complete, screw the adapter for the GAP 125 grille in place and clip the grille to it. Plug the air inlet into the duct.
