Choosing the right Air Door and Air Curtain

Air Doors (also called Air Curtains) are a very valuable addition to any busy entryway or service window. By producing a steady jet-stream of air across the width of any opening, these efficient units create a seamless air barrier between two separate environments. From entryways to window openings, and even drive-through, Air Doors allow open accessibility, while blocking out insects, dust, and other fumes through a protective curtain of air. They alsocreate huAir Curtainge energy savings by maintaining temperature separation between the two areas, keeping conditioned and heated air from escaping.

Location matters when selecting the right air door for your needs. Different locations can benefit from different types of Air Doors. For each instance you will need to consider where you will be using your unit. Front entryway? Back loading area? Drive-through? Home use? Different Air Doors are designed for a variety of different needs and applications.

Check out a few of the most popular uses:

For Entryways:

Smaller, light-weight Air Curtains and in-ceiling mounted units are beneficial to providing top-notch performance that still maintains a low-profile. In selecting a unit for an entrance, you’ll also want to consider your climate and how it affects your inside temperatures. Are you in a location where cold winter drafts are a possibility? Consider a heated Air Curtain to help neutralize extreme cold weather temperatures.

For Service Entrances:

Large service entryways often find themselves host to swarms of pesky insects trying to get at food and waste. Air Doors designed for backdoor and industrial applications often feature stronger motor power to help efficiently seal larger openings typically susceptible to annoying pests and outside fumes. Consider models built for industrial use and whether or not the increased power of an additional motor would create a better seal for these openings.

For Drive-Through:

It’s not only about keeping out insects, dirt, and harmful carbon monoxide fumes from car exhaust, you also have to be able to run a functional service window as well. Luckily, Drive-Through Air Doors not only do a great job at blocking out undesirables, they are also especially quiet, so as not to interfere when taking orders. The compact design provides a better fit for smaller service openings and most units have a heating upgrade available should you encounter cold climate seasons.

For Home:

Air doors aren’t reserved for commercial use alone. A selection of units come in low-voltage packages capable of being used in residential areas. By taking advantage of their unique ability to lock in air conditioning or heat and block out bugs, residential use can be a great way to keep busy backdoor patios open, available, and with a clear view of the kids or whatever else is happening in your backyard event.

Once you have an idea of the Air Curtain that fits your needs, the next big step will be in choosing the right size to Air Door for your operations.

There is no way around it, measuring is the best way to match the most accurate sized Air Door for your needs. Too small and you will create an inefficient barrier, too large and you will be wasting energy and money. Common sizes come in widths of 32”, 42”, 48”, 60” and 72”. You can order larger doors as well. Measure the height and width of the opening before purchasing to ensure maximum efficiency with your Air Curtain.
