9.  91 Percent of all fire/smoke and smoke dampers installed in the United States are 24” x 24” or installed in the United States are 24” x 24” or smaller based on historical averages. 24” x 24” is smaller based on historical averages. 24” x 24” is the maximum UL approved size for a FR or SR the maximum UL approved size for a FR or SR Series Damper.

10. The Annual Operating Cost (AOC) of any device installed in a duct system can be calculated using the industry accepted formula below: AOC = ($ / kwh)(cfm)(TFDP)(0.746 kw / hp) (hrs) (6350)(Nf)(Nm) Where, $ / kwh = Average Electrical Energy Cost = 0.10 cfm = Airflow Through Fitting in Cubic Feet per Minute = 2000 TFPD = Total Fitting Pressure Drop (Pressure Drop Saving in this Example) = 0.375 Nf = Fan Efficiency = 0.7 Nm = Motor Efficiency = 0.9 hrs = 8,760.  The formula for AOC is a generally accepted formula in the industry.  The values inserted into the formula were selected based on typical design parameters. air balance inc.

11. Using a 12” x 12” damper as an example, and taking the pressure drop information from the comparison chart and using $.10 cost per kilowatt hour the annual cost savings for the FR/SR compared to the traditional damper is calculated as follows: AOC = (0.1)(cfm)(in. wg)(0.746)(876) = $0.163 / cfm / in. wg (6350)(0.7)(0.9) Annual Operating Cost Savings = (0.163)(2000)(0.375) = $122.55 air balance inc.

12. And the very best part is that these savings are free! The FR/SR is the same cost as a traditional Fire/Smoke damper The AOC formula assumes building operation 24/7 which is unlikely in todays business climate, so lets assume that the average facility operates at 50 % of that.  The cost savings per damper would be: $ 61.28  Using the average order size of 78 dampers per commercial facility, the annual cost savings using the FR is: $ 4779.84  Given a thirty year life, the total savings over the life of the building is: $ 143,395.20 air balance inc.
