An air curtain is a fan-powered device that creates an invisible air barrier over the doorway to separate efficiently two different environments, without limiting the access of the people or vehicles. The energy saving air screen reduces heating and cooling costs by up to 80% while protecting the internal climate and increasing people comfort. It keeps the atmosphere clean from pest and insects, dust, airborne, pollution, smells, odors and stops draughts and cold or hot air entrance. The functioning of an air curtain is based on a high velocity jet of air that covers all openings. Heated air curtains creates comfort by the jet of air on people as they cross the air screen and helps to maintain the temperature on the entrance. XMK Large Air Volume Centrifugal Air curtain for ventilation air exchange, cold room gate, showroom gate and many more offices. Now available in Nepal with 100% copper motor at very affordable price.

Air curtain Applications

Door climate protection

First and foremost air curtains are designed to prevent a climate area (heated or cooled) from the influx of outside air through an open doorway. The air curtains reduce energy costs by keeping heated or cooled air in the internal building atmosphere. Efficient air curtains will save up to 80% energy looses across a doorway compared with a door without air curtain. During the winter an air curtain creates a barrier that keeps out the cold air while in the summer the air stream keeps out the hot air from outside. Bearing in mind the energy saved, the average payback time for an air curtain is between 2 and 5 years depending on usage and climate conditions.

Pest and flying insect control

Insect air curtains are commonly used, when necessary, to stop insects from entering a buildings like food processing plants, bakeries, restaurants, hospitals, etc. Bugs in flight approaching will be stopped by a barrier of air too powerful to penetrate. You need to select the correct air curtain for insect repellent applications. A very powerful air jet along the all doorway is needed (stronger than standard applications).

Cold storage

Due to big temperature differences, it is highly recommended to install air curtains to reduce the energy losses when the door is open. The higher the temperature differences between inside/outside, then higher are the energy losses when a door is unprotected. So the payback period of the air curtain is very short and then the energy/money saving is very high. Not only we will save money avoiding air transfer through the door but also will keep the frozen goods in perfect condition and help to reduce defrost costs of the cold room. For cold rooms and freezers air curtains are the safest way to protect the energy losses without any physical barrier that can create accidents or collisions on the doorway. For example, when plastic strip curtains are used the view across the doorway is limited and people or vehicles accidents occur, with compensation consequences. Besides it prevents bothersome and potentially dangerous fogging, humidity and ice formation in the door entrance area.

Dust, pollution and airborne control. Clean rooms.

Always installed in the clean side of the doorway, air curtains act as a barrier against dust, particles and humidity.
