How does it work?

FAIRAIR Air Barriers create an effective seal on the doorway by re-circulating the facility air in a laminar (smooth) flow across an open doorway. The kinetic energy in the moving air generates a barrier, like a waterfall, that prevents leakage of air between two areas with different pressure and climate. The more laminar this air flow, the harder it is for outside air to penetrate the barrier.


Enershield has developed three distinct air barrier systems for the industrial sector – Ultrashield, Xtremeshield, and Megashield. Ranging from 5.4 metres high to 13.5 metres high, these motorized doors provide an energy saving air barrier for a variety of industrial uses, including warehouse doors, receiving doors, and other industrial doors. Built to withstand the harshest of climates, these industrial air barrier systems will provide an economical and energy efficient way to operate.


Ultrashield, Xtremeshield & Megashield are designed for doors with a height of 5.4 - 13.5 m.
