In large structures with natural ventilation, propel fog
the length of the structure with the first fan row no more
than 25' from the end wall. The first fan should be:
- centered along the end wall (or)
- placed no more than 25' from the side wall,
with additional fans in the row equally spaced no
farther than 50' apart.
Lengthwise, the fans should be equally spaced and no
more than 50' apart. All fans should be equipped with
oscillation, sweeping 360˚.
Large Structures,
Closed or Minimum Ventilation
In closed structures with little to no ventilation, propel
fog the length of the structure with the first fan row no
more than 40' from the end wall. The first fan should
either be:
- centered along the end wall (or)
- placed no more than 40' from the side wall,
with additional fans in the row equally spaced
no farther than 80' apart.
Lengthwise, the fans should be equally spaced and no
