HOW TO CHOOSE A FAN

Ceiling fan choice and layout is based on ceiling height and the floor area of the building. As the height of the ceiling increases, larger and more powerful fans are required
to achieve destratification.

The floor air coverage of a fan will be greater the higher the ceiling of the building. This is because of the natural cone shape of the air pattern produced by the fan. *HPWP models
have increased floor area coverage because of more powerful motors.

Canarm provides two types of fans:

• The traditional ceiling fan, low cost, good performance, great for dry locations.
• The HPWP high performance, water resistant models - great for more demanding applications with high moisture or greater air velocity requirements. Use the chart
  to help choose the correct fan size/type and quantity to suit your requirements.

Example:

What size and how many fans would be required for a building that is 100 feet wide x 200 feet long and has aceiling height of 16 feet? A typical layout for a building is illustrated.

• By using the chart, we see that a ceiling height of 16 feet requires a CP56 (56" fan).
• Floor Area of the building = 100 feet wide x 200 feet long - 20,000 square feet.
• From the chart, we know that the Fan Floor Area. Coverage of the CP56 model is 1100 square feet at a 16 foot ceiling height.
• Therefore, the number of fans required = Floor Area of building / Fan Floor Area Coverage 20,000 square feet / 1100 square feet = 18 fans.

NOTE: An additional fan should be used about 10 feet in front of each shipping door to act as an air curtain and reduce heating bills in the winter.
