Maco (Austria)

MACO has developed a system of step-by-step ventilation, which allows for the possibility of intermediate flaps. The essence of this system is the additional installation of the locking step step in the scissors. This element provides three additional intermediate flap positions, thereby achieving five fixed flap positions together with scissors.
This item is an additional option and has its own item number. Apply to both standard and microwave scissors. It is easy to install both with the initial installation of the accessories and with the windows installed on the object.

Allows you to open and lock the shutter at a distance of 5 to 33 millimeters from the frame. In this case, the thrown flap by rotating the handle 45 degrees upwards is fixed (depending on the profile) in one of the 5 selected positions, ensuring the flow of fresh air into the room of varying intensity.

Slit microwave ventilation

It will allow airing in a neat and unnoticeable way for those who are indoors. In this case, the leaf is only a few millimeters away. It is very convenient for night airing in the cold season, as well as for use in children’s, sleeping rooms, kitchens and rooms with drafts.

Comb

The comb ventilation method is more popular due to its simplicity of technology and rapid achievement of the desired result. The window equipped with a comb can be easily locked in the open position. In this case, fresh air will flow into the room through the gap created between the frame and the sash. The comb allows to fix the window in an inclined or open position with a gap between the frame and the shutter from about 10 to 70 mm. This fixture is versatile and is used for both multi-stage flap rotation and multi-stage folding.

Multivent

Universal key-locked ventilator for plastic windows. This mechanism will not allow the child to fully open the window. The plastic window will be in the ventilation mode. Easy to install on any accessory. The leaf can be folded, rotated within 4-5 cm, left in the gap ventilation.

Rigel Air

The ventilation valve of a window fold, consisting of two separate parts in width of 125 mm. The air enters the fold through the lower part of the leaf and rises up between the leaf and the frame. There, already preheated, it passes through a built-in valve and then enters the room. This valve acts as a valve regardless of the air flow rate, ie wind pressure. The stronger it blows outside, the smaller the air-permeable hole becomes. A controlled flow of between 8 and 60 Pa provides a uniform flow of air. There are no drafts in the room because the air exchange occurs at the top of the ceiling.
