1 Working principle
The air of indoor sucked in by the cross flow fan of the air curtain, blown down to the floor at a high
speed. And the downward airflow 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 airflow 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 efficiency, the air outer of the air curtain should be paralleled with the
door head, ensure that the speed of airflow which arrived at the floor should be more than 2.5meters/sec.
