Yorco Air Curtain YSI-201


Air Curtain

An Air Curtain is used as a dust, insect and temperature bearer between 2 areas by providing and invisible curtain of air across the door opening through which persons and material movement can be made freely.

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) defines an air door as follows: "In its simplest application, an air curtain is a continuous broad stream of air circulated across a doorway of a conditioned space. It reduces penetration of insects and unconditioned air into a conditioned space by forcing an air stream over the entire entrance. The air stream layer moves with a velocity and angle such that any air that tries to penetrate the curtain is entrained.

The Air Movement and Control Association (AMCA) defines an air curtain as: "A directionally-controlled airstream, moving across the entire height and width of an opening, which reduces the infiltration or transfer of air from one side of the opening to the other and/or inhibits flying insects, dust or debris from passing through".

Yorco Air Curtain is a very well designed product for this purpose.

The most common application area includes Hospitals Entrances, air conditioned showrooms, Restaurants, Hotels, Malls, Pharmaceutical and Electronic Industries. Due to prevention of heat loss even on and open door it helps in energy conservation also.
