Canarm’s standard fans follow a tradition of quality in design, materials and construction. All our standard fans are developed to be efficient and economically priced. All variable speed standard fans use an energy efficient variable speed, dual voltage motor and blade combination.
To determine the proper Canarm Fan for your applications, use the following formula.
Number of cubic feet in room / Number of minutes per air change = Required C.F.M. Capacity
A general office, (see chart) which requires an air change every ten minutes, would require the following fan capacity.
If office is 100’ x 40’ x 10’ = 40,000 cubic feet
40,000 cubic feet / 10 minutes per air change = 4000 Required C.F.M.
From this chart, you would select a fan that is rated at 4000 C.F.M. at 1/8” S.P. (Static Pressure)
