External wall cowl CE2A more information

Slot (in mm) 354 x 12



The M-G adjustable self-regulating air inlet, fitted indoors, is made from polystyrene and fulfils tjhe insect screen function. For installation in main rooms (living and bedroom) to supply air renewal to single flowrate forced ventilation systems.

Available in flow ratings of 15, 22, 30, and 45m³/h. The 15 m³/h air inlet also enables 22 and 30m³/h flowrates and the 22m³/h air inlet goes up to 30m³/h.

It works both on vertical walls and on inclined planes (e.g., roof skylights, undersides of roller shutter boxes). The cowl or grille for the external wall is made from UV- and weather-resistant polystyrene in the same colours as the air inlets (except the GAE2A aluminium outer wall grille).
Exclusively for fitting to surfaces sheltered from bad weather. For non-sheltered surfaces please enquire with us.

On the inside, the air inlet is centred on 354 x 12mm slot and held in place by 2 screws.

For fitting to curved joinery, insert the round-fit base between the air inlet and the joinery.

The external wall cowl or grille is centred on the slot and held in place by 3 screws (horizontal fitting cap).

The components must be kept easily accessible for cleaning and maintenance.

The fastening holes in the air inlet and cowl can be concealed with screwhead covers (sold only with the kits).

M-G 15/22/30 m³/h air inlets: the inlet airflow rate is determined by the snap-off tabs (marked 15, 22, and 30) on the two regulator bar holding clips. The lowest remaining value indicates the flowrate.

The 15m³/h model can also be modified in-situ to provide flowrates of flowrates of 22 or 30 m³/h by carefully breaking off the relevant snap-off tabs. Break the 2 tabs marked 15 to obtain 22m³/h and the 2 tabs marked 22 to obtain 30 m³/h.

The 22m³/h model can also be modified in-situ to provide a flowrate of 30 m³/h by carefully breaking off the relevant snap-off tabs. Break the 2 tabs marked 22 to obtain 30 m³/h.


M-G 45m³/h air inlet: the inlet airflow rate is found on the two retaining clips of the regulator bar (marking 45).
