FAN LOCATION:
These fans should be positioned to move air in stagnate locations, or to generate airflow over livestock to keep them cool, and
keep flies away. Some typical fan layout options are listed below.
1. ELIMINATING STAGNATE LOCATIONS IN FORCED AIR VENTILATED BUILDINGS
To move air in stagnate locations, position fan or fans to force air through. See
Figure 2
.
NOTE:
Depending on size of stagnate area, more or less fans may be used.

2. GENERATING AIR FLOW IN NATURALLY VENTILATED BUILDINGS.
To generate airflow over livestock, fans should be spaced according to velocity diagrams below. A general rule of thumb is to
space them at a distance that will maintain a flow of 200ft/min. For example, CA24AG-GVII should be spaced out approximately
every 55ft. (See
Figure 3
for typical layout, see velocity mapping diagrams on next page.)
NOTE:
Fans spaced so minimum airspeed is 200ft/min.
(Typical “racetrack” configuration for naturally ventilated buildings).

WARNING: MOTORS ARE EQUIPPED WITH AUTOMATIC OVERLOAD PROTECTION AND MAY RESTART
WITHOUT WARNING. ALWAYS DISCONNECT POWER BEFORE ATTEMPTING TO SERVICE.
MAINTENANCE:
WARNING
Moving parts,
disconnect power
before servicing.
!
These fans are virtually maintenance free. Motor, blade and especially the guard, should be kept clean of any dirt build up to
prevent premature motor failure and to achieve proper performance.
CAUTION:
If using a variable speed control, the minimum speed setting on the control should be set to half of the full load
voltage. (i.e. If fan is wired at 230V, the minimum speed setting should be set to run the fan at 115V).
CAUTION:
When operating the fans in cooler weather be careful not to direct the airstream on to the animals. Cold drafts can
cause health problems.
