The AST 2x75/125 – 300mm NEW air supply and exhaust box is part of the ModulAir system. This model has two connectors with a diameter of Ø75 mm for connecting ventilation ducts and a part with a length of 300 mm for mounting a Ø125 diffuser.

The box is made of polypropylene, and its smooth inner layer prevents dirt from settling. The unique shape allows the free flow of air, which does not break against the internal walls, creating noise.

The click system used in the box allows for quick connection of ventilation ducts and prevents their accidental disconnection.

The construction of the air supply and exhaust box enables its installation both vertically (in the layers of the floor or in the suspended ceiling structure) and horizontally (in the frame walls). The stabilization of the element in the building structure is ensured by two mounting brackets.

The dedicated Ø125 mm CLASSIC end cap NEW allows you to close the 125 mm connector for the time of renovation, and the Ø75 mm plug closes the Ø75 connector to which the ventilation duct has not been connected.
