The CFM potential of a blower is determined by the horsepower capacity of the motor and the size of the blower’s fan. The blower fan assemblies are factory designed and tested, and then they are given a CFM rating – meaning they are rated for how many cubic feet (one foot x one foo...
Calculate the flow area. For ducts, this is the width multiplied by the height. For pipes it is the height of the pipe multiplied by the width of the pipe. The flow area is noted as feet squared. Divide the rate of flow by the area of flow. The result should be recorded as feet ...

A backward inclined fanis used predominantly in the exhaust of a paint booth or spray application because it is engineered to handle the paint overspray in the air and it can handle greater static pressure. How do I calculate cfm? This practical math formula goes a long way when you're con...
Calculate the CFM (cubic feet per minute) venting requirement for your greenhouse. Purchase the required size exhaust fan and shutter size. Mount the exhaust fan on one side of the greenhouse and the shutter on the opposite side of the greenhouse. Refer to the installation instructions of each...
better, the entry should be “”tight” or maybe semi-tight.” Better would be to use an actual blower door number. For example,if your code requires 3 ACH50, enter that into the calculation. If you’re going for Passive House certification, enter 0.6 ACH50 or 0.05 cfm50/sf of ...
Travel-sized steamers are compact, hand-held versions of these machines, in which a small water tank is connected directly to the steam blower, without a hose or rod. The time it takes for a steamer to remove wrinkles -- and how well it does the job -- depends on a variety of ...
For the purposes of this article, assume there are no leaks in the R-410A system. If a system is leaking it must be repaired before recharging. Inspect the coils, blower wheels and the blower motor speed to insure they are operating properly. Using the temperature rise method (CFM = KW...
