1 Working principle

The air of indoor sucked in by the cross ow fan of the air curtain, blown down to the oor at a high

speed. And the downward airow formed an invisible“wall”.

The air curtain is usually installed on the upside of the door the window, when the door or the window

is opened, the airow of the air curtain could isolate the air of the indoor side and outdoor side effectively.

Thus the cool air leaking of the indoor side can be reduced, and can prevent the mosquitoes and dust from

entering into the room as well.

The length of air curtain should be consonance with the width of the door or the window, put two sets

of unit or more side by side to cover the width of the door or window entirely.

In order to obtain more effective efciency, the air outer of the air curtain should be paralleled with the

door head, ensure that the speed of airow which arrived at the oor should be more than 2.5meters/sec.
