AIRDOOR

AirDoor is a revolutionary alternative to traditional air curtains

It employs a three-sided air curtain with active, targeted airflow to enhance interior comfort and boost the building’s energy efficiency. Situated directly inside the entrance, it generates a plume of air to reduce weather-related infiltration, such as wind (temperature & humidity disruption), dust, pollution and wind-driven rain (slippery floors). This enables retailers to better utilise the front-of-store area and helps food display equipment run more efficiently. While heated/cooled air curtains cost you money, AirDoor delivers a positive ROI.
