AD 400

AD400 is an air curtain with a modern design intended for permanent installation above doorways with heights up to 4 meters. By separating zones of different temperature with a jet of air, AD300 effectively prevents cold draughts through open doorways and provides good heating comfort and the opportunity to make use of the floor space close to the opening. AD300 can also be used for heating and drying at the opening.

AG 4500/5000

AG4500/5000 is a product series for larger entrances and doors. With a clean, stylish and simple design, it's ideal for both shop entrances and industrial doors.

AG4500/5000 creates an air barrier that effectively prevents cold draughts and provides a comfortable environment inside the door that allows you to utilize the floor space in front of the entrance. Major savings are made by the elimination of energy losses through openings. In addition to preventing cold draughts, the AG4500/5000 prevents odours, exhaust gases and insects from penetrating the opening.

AG4500/5000 with heat contributes to heating the building and can also be used for drying in front of the door where a lot of snow and water enters.

AC 500

AC500 air curtains are intended for permanent installation above doorways with heights of between 3 and 6 meters. By separating zones of different temperature with a jet of air, the AC500 effectively prevents leakages of heated or refrigerated air. In this way, the energy loss is significantly reduced and a comfortable indoor climate can be maintained. When used in freezers and cold storage areas, it reduces humidity and ice build up.

The air curtain also helps to improve the working environment by preventing the intrusion of insects, dusts, and exhaust fumes.

Because the air intake is high where the air is warmer, the temperature difference between ceiling and floor is equalized. The AC500 is built with axial fans that combine high pressure with high flow. High velocity air exhausts through a honeycomb grid resulting in a well defined and layered air stream. There are two ways to direct the air stream for maximum performance: either by tilting the whole unit, or by adjustment of the air directors.

For wide doorways, several units can be mounted next to each other. When space above the doorway is limited, the units can be mounted standing vertically besides the opening.

AC 600

AC600 creates a very effective air curtain when the air at high speed is pressed out through a narrow slot in the floor inside the door opening. The air curtain is directed upward which gives the best possible protection against colder and heavier streaming into the room. The AC600 unit consists of a pillar with an inlet hood, silencers, and fans. It's placed inside and next to the door opening. The floor duct has its slot at floor level. The width of the slot and the blow angle are determined when projections are made.
