Enershield Durashield HD Air Barrier

Durashield HD (DSH) Air Barriers are designed for doors that are 10’ to 12’ in height. Durashield HD models are constructed from a welded powder coated frame and are insulated with sound absorbing fibreglass insulation with an acrylic anti-microbial coating, powder coated telescopic installation sliders and include powder coated wall brackets as well as an articulating discharge nozzle. All models also include an Automatic Activation Package so the Air Barrier operates in conjunction with the doors operation.

Features

Durashield HD models include a Control Panel. Motors are mounted externally to maintain consistent and equal fan placement across the entire width of the Air Barrier (every 2'). Durashield HD Air Barriers are ideal for Shipping/Receiving, Manufacturing or Freezer applications. They can also be installed horizontally or vertically. We would be glad to supply you with an Energy Loss Calculation (using an ASHRAE formula) to show you what you are losing in energy as well as what we can save you in energy based on the amount of time the door is opened.
