Air Curtains Information

Show all Air Curtains Manufacturers

Air curtains produce a downward stream of air over doorways to prevent the exchange of air between two environments. They are most commonly used to reduce the transfer of air between two environments of different temperatures, such as conditioned and unconditioned atmospheres. Air curtains are estimated to be between 60—80% effective at curtailing the exchange of ambient environments. Air curtains are also effective at reducing the infiltration of an environment by airborne insects. Air curtains are frequently used in commercial or environmental sliding doors, or other doorways where operations require easy access.
