Air Curtain

An air curtain, also called an air door, makes an invisible door that separates the ideal temperatures inside and outside.

They keep air from coming in through an open door by adding a fast-moving, streamlined air stream.

Creating an air partition between two areas prevents outdoor air from entering and indoor air from escaping.

This helps the HVAC system work more efficiently by protecting the air-conditioned facilities. This in turn reduces overall energy costs (scientific study).

The latest technology allows air doors to work systematically and maintain the optimum balance between velocity & volume. Having an optimized balance allows air doors to operate at a more comfortable sound level.

Choosing the Right Air Curtain for Your Application

When choosing the best air curtain for your application, there are several important points to consider:

Installation height and height of the opening are two different things. They are installed at a higher point than the actual opening.
The unit is most efficient when placed as close to the opening as possible. This creates an effective seal between two temperature zones.
Models are available with heating capabilities.
The pressure between areas shouldnt be too excessive. It’s important to have an engineer survey the area for proper ventilation.
The entire area must be completely covered, both width and height. R. Williamson & Associates offers air curtains in a wide variety of lengths. However, some areas require more than one air curtain.
Working within your budget. Just because the air curtain has the best price doesnt make it the best choice for your application. Contact a professional to see what's the best air curtain for your price budget.
