Hydraulic Tube Bending – A Simplified Guide
Efficiency and precision in industrial tube bending are paramount for achieving…
Read BlogCFM, or cubic feet per minute, is used to measure the rate at which air is moving. Horsepower (HP) is used to measure the power of the blower in a dust collection unit. This ratio of CFM versus horsepower is important, since the goal is to get the ideal CFM with the lowest horsepower to save on energy costs.
In dust collection, you must also factor in static pressure (SP). Static pressure is the resistance to flow measured in inches of water (wc). To move a given amount of CFM, the fan requires a certain amount of horsepower to move the air at a given static pressure.
For example, say you know that you need 6,000 cfm at 6″ of static pressure for a CNC molder machine. Due to the loss of friction through ductwork and the dust collection system, you add another 4″ of static pressure, making a total of 10″ of static pressure. Based on that, you need to move 6,000 cfm at 10”.
Using the diagram below, you can determine what horsepower the most efficient blower needs to be to get your ideal CFM. Apply this information as you browse our selection of Industrial Dust Collectors to find the right fit for your needs.
After reading this performance curve, a size 15 HP blower is going to get you 5,900 cfm at 10” SP. You know that you are maxing out the motor so there is no wasted energy. Contact us today for more information.
