Product Overview

Powerful Air Protection for Commercial Entrances

The Mitsubishi Electric GK-3009AS2 Air Curtain creates a powerful downward stream of air across commercial doorways up to 900mm wide, helping reduce the exchange of indoor and outdoor air when doors are open.

Ideal for retail shops, offices, restaurants and commercial entrances, this high-velocity air curtain helps maintain indoor comfort while allowing customers and staff to move freely through the doorway.

By reducing the movement of heated and cooled air through open entrances, the GK-3009AS2 can help minimise energy losses and reduce the heating and cooling demand on air conditioning systems.

Featuring five axial flow fans, two-speed operation and a maximum air velocity of 12 m/s, this air curtain provides effective air separation for busy commercial environments.

Key Features

Powerful High-Velocity Air Barrier

Produces a downward stream of air with a maximum velocity of 12 m/s, helping reduce unwanted air movement through open doorways.

Helps Maintain Indoor Comfort
