MOUNTING or Section IV - SUSPENDED
MOUNTING |
|
|
The
air curtain will not perform properly if negative
air pressure exists in the building. Under these
conditions, a means for makeup air to the building
must be provided so that the air pressure on both
sides of the opening is in balance. |
|
|
|
|
|
|
|
