Modern PVC windows are really hermetic. Using Aereco air inlets modulate the airflow according to the local relative humidity rate.
2MO self regulating pressure inlets to instal in alu and pvc windows. It is available in 3 colours: white (RAL 9003), chestnut (RAL 8017) and oak (RAL 8001). The width of the inlet is 290mm so it can instaled on a narrow windows sashes. We can coat the inlets to any colour.
Areco 2MO
The 2MO inlet consist of 2 parts: an outside - a canopy to protect against rain and insects and an inlet to control air-flow. Instead of a canopy can be mounted a gable vent for the windows with a roller blind.
An inlet in open position C the amount of air supplied depends on the difference between the pressure inside and outside the room. The air - flow depends to the type of the inlet and is up to 20 m3/h. A greater increase results in the wings limiting the amount of air entering. The user has the option (position D) of closing the diaphragm and thus reducing the air flow to a minimum. Air from the outside is flowing verticaly. The user has the option of closing the diaphragm and thus reducing the air flow to a minimum.
The 2MO inlet is in 2 versions: A and B. A version - after removing a wall in the back side of the inlet there are 2 holes, B version - have 3 holes after removing 2 fringe walls.Both versions have different air-flow, which is showed on the graph.
Self regulating pressure inlets – the amount of air supplied depends on the difference between the pressure inside and outside the room. This happens until the difference in pressure reaches that level at which the intake vent operates most effectively. A greater increase results in the wings limiting the amount of air entering. Such a situation may be caused by a draft of air.
