HOW TO CALCULATE THE NUMBER OF BUCKET FANS YOU NEED

To enjoy the full benefit of destratification the accepted rule of thumb is to "turn the air" between one and two times an hour.

For ceiling heights 15 ft - 20 ft use the Bucket Fan 420

For ceiling heights 20 ft - 25 ft use the Bucket Fan 1055

For ceiling heights 25 ft and over use the Bucket Fan 1460

To determine how many Bucket Fans are needed use this formula:

1) L x W x H = V (Height x Width x Length = Air Volume in Building)

For Example

A building that has the following dimensions:

125 ft long, 75 ft wide, and 20 ft high.

1) 125 x 75 x 20 = 187,500 cu. ft

2) 187,500/1055/60 = 2.96 fans
V / CFM of the Bucket Fan / 60 (converts CFM to CFH) = Number of Fans

3) V / CFM / 60 = Number of Fans

Always round up to the next number. In this example 4 Bucket Fans would be needed.
