an air curtain for Flying Insect
control, it is important to know the height
of the opening to determine the right
amount of air velocity to effectively
control flying insects from entering the
building. Air curtains for back doors
and delivery doors require a minimum of
1,600 cfm(cubic feet per minute) for flying
insect control. More is always better.
A Mars Microswitch(Door Limit Switch)
turns the air curtain On/Off as the door
is OPENED/CLOSED automatically. This means
no one needs to flip a switch to turn
the unit on before the door is opened.
