Air Curtains
Air curtains create a directed sheet of air across a doorway, forming a barrier that separates conditioned or refrigerated indoor air from outdoor or ambient air without closing the door. They're used at retail entrances to keep conditioned air in while doors stay open to customers, and at cold room, loading bay and cold-chain doors to limit temperature loss and insect/dust ingress.

Frequently Asked Questions
Do air curtains fully replace the need for a closed door?
No, they reduce air exchange and temperature loss while a door stays open for traffic flow, but they don't provide the same barrier as a fully closed, sealed door: best used to manage frequently-opened doorways.
Are heated air curtains necessary in Nairobi?
Most entrance applications in Kenya's climate use unheated units; heated models are typically reserved for specific cold-chain or cooler-climate applications.
