Air Curtains

An air curtain, also known as an air door, creates an invisible door that effectively separates ideal indoor and outdoor temperatures. They work by adding a streamlined, fast-moving air stream to prevent air penetrating through the open doorway.

By creating an air partition between two areas, it 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.

Blocking Pests & Contaminates

Pests and insects not only make life for clients, customers and staff uncomfortable, but they also have the ability to contaminate products in many industries.

They’re also useful in ensuring that harmful fumes or harsh irritants don’t affect staff.

Choosing the Best Air Curtain

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 are available. This allows the area to be heated when doors are closed.
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.
