Horizontal Air Flow (HAF) Fans<br />

Calculating HAF Fan Requirements<br />

Versa-Kool HAF Fans<br />

Theses patented fans are very quiet,<br />

highly efficient and durable!<br />

Features:<br />

• Fan guard spacing is larger than<br />

traditional basket fans and<br />

provides more air movement<br />

• Heavy-duty, totally enclosed,<br />

maintenance free and energy<br />

efficient motors<br />

• Noise levels are low<br />

• Tapered vinyl coated fan guard<br />

• Heavy-duty aluminum blades<br />

• Standard cord length of 5’ ( 8’ or<br />

10’ is also available as special order.) Please specify at time of order<br />

Typical fan placement for<br />

free standing greenhouse<br />

Fan selection is based upon 2.5 to 3 cu ft/minute (CFM) of<br />

greenhouse floor area. Example: length x width x 2.5 or 3 = total<br />

CFM required. Next divide the total CFM required, by the CFM<br />

performance. This equals the approximate number of fans required.<br />
