Large structures, Natural ventilation
In large structures with natural ventilation, propel fog
the length of the structure with the first fan row no
more than 30' from the end wall. The first fan should
be:
- centered along the end wall (or)
- placed no more than 30' from the side wall, with
additional fans in the row equally spaced no
farther than 60' apart.
Lengthwise, the fans should be equally spaced and no
more than 60' 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 50' from the end wall. The first fan should
either be:
- centered along the end wall (or)
- placed no more than 50' from the side wall, with
additional fans in the row equally spaced
no farther than 100' apart.
Lengthwise, the fans should be equally spaced and no
farther than 100' apart. All fans should be equipped
with oscillation, sweeping 360˚.
