Types of Air Curtains and Their Applications

According to the application and aerodynamic pattern, the following types ot air curtains have been designed  

Air curtains for process equipment are designed to prevent toxic constituents from entering the room through apertures of the equipment. 

The traditional design pattern (to be described in Section 7.7.5) is recommended for air curtains with heated indoor air. The air curtain may be doublesided with horizontal supply (Fig. 7.S6a), or it may be single-sided (Fig. 7.86f ) with horizontal or vertical supply. In all cases, the air curtain is a flat jet discharged at an angle toward the pressure side of the opening.

Air curtains with unheated indttor air are more restricted in application than air curtains with heated indoor air, but they do not require the insrallatton of ail heaters in the curtain devices.
