Ready to Install is the phrase most associated with the GPX SERIES FANS. Simply cut a square opening in the wall (the size shown below for housing dimension B, plus 1/4 inch). Slide the fan into the opening from the outside of the structure. Fasten the flange securely to your structure. Last, connect motor to a 115 volt , 60 Hz, single phase power source and your fan is ready to exhaust your building. Motors are 115 Volt Totally Enclosed Air Over (TEAO)

 Note: Consult the sales department for hazardous location applications.

Calculation for Sizing your Fan
For cooling people we suggest 2 to 4 minute single air change
For cooling product we suggest 4 to 6 minute single air change
For removing stagnant air we suggest 6 to 10 minute single air change
Calculation:
      A. Building Structure: Length x Width x Ceiling Height = Cubic Feet
      B. Decide how many minutes per single air change you require ( 2 thru 10 ) (Note: Your climate or equipment may
          alter your minutes required)
      C. Divide A by B = Cubic Feet Per Minute (CFM) Air Flow required
Example:

• Building Structure: 20' L x 30' W x 8' H = 4,800 Cubic Feet
• 4,800 / 2 minute single air change = 2,400 CFM Air Flow required
• Suggested Fan Size: GPX 1611
