Product applications
Air curtains are advanced, high-velocity fans that establish an imperceptible barrier of air across doorways. This innovative solution effectively segregates indoor and outdoor environments while maintaining distinct temperature zones. By preventing the loss of conditioned air to the outside, air curtains play a pivotal role in energy conservation. Additionally, they act as a formidable shield against dust infiltration, smoke penetration, and the entry of flying insects, ensuring a cleaner and more controlled indoor atmosphere.
