Here we provide Air Curtain which is simple to set up and sit nicely over the doorway. This utilizes less additional heat than vestibule heaters, which improves employee comfort while also lowering liability by keeping entryway flooring dry during severe weather. It also prevents a large portion of the conditioned air inside the structure from escaping. Right now, Air Curtain is available in a few ranges like wall mounted air curtain, and 2 feet air curtain. This allows for unfettered traffic flow while also improving cleanliness by minimizing insect ingress and keeping dust and odors out.
