Product Details

Air Curtain Overview

  Air curtains produce a high-speed current of air that blows downwards in order to form a barrier between two different environments. They are typically hung over doorways, and you will often see them in shopping malls, fast food restaurants, transit stations, and other crowded locations with heavy foot traffic. Air curtains serve the purpose of keeping the air in the interior environment separated from the exterior environment. This has the added benefit of keeping the air conditioned interior air from leaking outside, and saving on energy costs. It can also protect the interior environment from cold or hot air, smoke, insects, and bad odors.  In this way an air curtain acts almost like an invisible second door.

 YiJing Air Curtain Advantages

Heat/Cold Insulation

 For environments like restaurants, hotels, and other commercial locations with near-constant foot traffic, an YiJing air curtain can help provide an insulation effect of 60-80% to keep your customers comfortable.

Insect Protection

  Insects such as flies and mosquitoes cannot pass through an activated air curtain, which means your environment, personnel, and customers will have a refuge from these pests during warmer weather.

Dust Barrier

 For environments like precision machine shops, clothing stores, or even shops that sell food that are located near a bus stop, an air curtain can provide 60-80% insulation from exterior dust particles.

Continuous Fresh Air

 Air curtains can prevent enviromental contamination by unpleasant odors in settings such as laboratories, markets, restaurants, and even manufacturing and cold storage facilities. In areas near crowded roads, they can also prevent car exhaust fumes from entering the environment.

Negative Ion Technology
