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.
• Nafuji air curtain
• Nedfon air curtain
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, odours 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.
• All studies and tests have proven that air curtains are effective. When an efficient air curtain is well installed it save lots of energy and at the same time the entrance areas remain climate protected, comfortable and free of draughts, insects, odours, etc.
• The air jet of the air curtain placed on top, clearly divide the warm and the cold area in two thermal zones.
• The air curtain keeps internal environment on the left side of the image at comfortable warm temperature and avoids cold air penetration from the outside. In this second situation, the air curtain saves up to 80% of the energy given by the heater placed on the left wall.
Important Note: Poorly designed air curtains, wrong selected units (less powerful) or inadequate installation will loose part or even all the advantages and became worse than unprotected door.
