An air curtain is a simple way to control air flow between two spaces without creating a physical barrier. Doors and actual cloth or plastic curtains can cause a delay or inconvenience for an employee, especially if that person is carrying something. Using air curtains for doors allows people to pass freely while maintaining temperature control and preventing contaminants from entering the space.

Often used at an exterior entrance, a commercial air curtain blows air down in the doorway, creating a seal that can stop bugs, dirt, and debris from passing through. It's also highly effective for separating two spaces that are kept at different temperatures, allowing greater efficiency for your heating or cooling system in each space. We carry TPI air curtains in a variety of sizes. Air curtain heaters are also available, which create a veil of warm air as you pass through the opening. Take a look at our selection:
