Sonniger Guard One - door air curtains for small spaces

Sonniger Guard One door air curtains are air handling devices that create an air barrier between environments with different temperatures (indoor and outdoor) when the door is open, preventing cold air from entering the interior. Sonniger Guard One air door screens are designed for small entryways. Sonniger Guard One design door screens therefore protect against heat loss in winter and serve as a protection against the penetration of hot air into the interior in summer.

The Sonniger Guard One door screens are installed horizontally on the wall using brackets (accessories) or under the ceiling using threaded rods. Sonniger Guard One door screens are available in the following versions: with electric heating and without heating. The Sonniger Guard One door screen is equipped with an integrated motion sensor and a connection cable to the socket.

Usage:

in winter - protection against heat loss (preventing warm air from escaping when the door is open)
in summer - prevents the escape of cold air from the interior (and vice versa - hot air into the interior)
