What's the benefit?

• Doors can remain open
  By creating an 'invisible door' using the fast moving airstream people can pass easily from area to area without doors hindering progress.
• Prevents heated or cooled air escaping
  An effective air curtain separates two zones allowing different temperatures to be maintained.
• Reduces draughts and discomfort
  Comfort levels for staff, customers and visitors close to the doorway are increased by air curtains reducing draughts through frequently opening doorways.
• Energy saving
  Costs of running heating and air conditioning systems can be reduced with air curtains as they help to seal the building from the environment, making the building more energy efficient.
• Reduced ingress of insects and pollutants
  Insects, pollens and other airborne pollutants can be minimised with air curtains as they block much of these from entering the building.

How do they work?

1. Air curtains work by separating two different temperature zones with an invisible curtain of air. They provide a fast moving air stream to block air movement through the door whilst allowing the door to remain open.
2. Placing an air curtain above or to the side of the entrance covering the full door width maximises performance by stopping heated air escaping in winter, or cooled air escaping in summertime.
3. Positioning the air curtain too far from the entrance compromises performance with air leaking around the airstream.
4. Where extractor units are used within the building, ventilation should also be provided to equalise pressure differences for maximum air curtain effectiveness.
5. By retaining the cooled air within a cold storage room, an air curtain dramatically reduces waste energy and gives unhindered access from area to area. With no doors or curtains to reduce visibility, user safety is improved for those moving around the building.
