Enershield Megashield Air Barrier

Megashield (MS) Air Barriers are designed for doors that are between 28’ to 45’ feet in height. Megashield 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

Megashield 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 3’). Megashield Air Barriers are ideal for large Shipping/Receiving, Manufacturing or Transportation applications. They can be installed horizontally. 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. Contact us for additional information regarding this model.
