When shopping for new automotive components, it never fails that we are bombarded with tricky sounding terms and acronyms. Many times, we are casually familiar with these acronyms and we may know what they stand for, but don\u2019t actually know what it does. Take CFM for example. Most people can correctly state that CFM stands for Cubic Feet per Minute and it is a measurement of airflow. But, what does it really mean to car enthusiasts?<\/span><\/p>\n

It is not uncommon to hear salesmen quote CFM numbers when explaining cooling fans. From time to time, you may also hear one representative explain how company X\u2019s CFM numbers are not as accurate as company Y\u2019s. So we approached the specialists at\u00a0<\/span>SPAL USA<\/a>\u00a0<\/span>to explain CFM to us.<\/span><\/p>\n

\u201c<\/span>One of the most common questions we hear from customers is \u2018What is the CFM rating?\u2019 of a particular fan,\u201d said Thom Balistrieri, director of aftermarket sales for SPAL USA. \u201cThis is a tricky question, as it\u2019s very important to understand how CFM ratings are determined as well as how much CFM an application actually requires.\u201d<\/span><\/p>\n

\"\"<\/a><\/p>\n

According to Balistrieri, CFM ratings should be looked at subjectively because there is not an accepted standalone method of measure when it comes to determining CFM ratings.<\/span><\/p>\n

\u201cThink of it like wheel horsepower. Different dynamometers [dynos] will give different wheel horsepower ratings,\u201d Balistrieri explained. \u201cSometimes, there is a \u2018correction factor\u2019 from one dyno manufacturer to another. This is the same situation, where measuring on a machine with different certifications could give different data.\u201d<\/span><\/p>\n

<\/span><\/strong><\/h4>\n

Tabular Data<\/span><\/strong><\/h4>\n

SPAL uses a broader spectrum of CFM data for consumers to understand a fan\u2019s ratings. \u201cWe provide tabular airflow data to our customers,\u201d Balistrieri added. \u201cThis tabular data allows our customers to see how the fans perform across the entire static-pressure range.\u00a0\u00a0<\/span><\/span>This is critical information when selecting the correct fan for the job, and often, the most misunderstood aspect of fan selection,\u201d he said.\u00a0\u00a0<\/span><\/span>\u201cWhen customers don\u2019t consider the static pressure drop of the radiator, it\u2019s easy to get a fan that is underpowered for the task.\u201d\u00a0<\/span><\/p>\n

\"\"<\/a><\/p>\n


<\/span><\/p>\n

Balistrieri\u2019s advice is to not get misled by trying to standardize and compare all the different methods of CFM measurement in the industry. He says there is an easier approach. \u201cOne way to determine if CFM ratings make sense is to look at the current draw of the fan.\u201d<\/span><\/p>\n

This approach states the current draw (in amps) is proportional to overall fan performance. \u201cMotor-current draw is directly related to motor torque and the amount of pressure the fan can generate to overcome the restriction of the radiator,\u201d he said. To put it even more simply: Increased amperage typically equates to increased airflow.<\/span><\/p>\n

\u201cWe have a fan to solve nearly any circumstance you can imagine,\u201d added Balistrieri. We actually put together an article about fan selection, and you can\u00a0<\/span>find that information by clicking here<\/a>. According to Balistrieri,\u00a0 \u201cjust call (800) 345-0327 to talk to an experienced technician and determine which SPAL fan is best for you.\u201d Or visit them online at\u00a0<\/span>www.spalusa.com<\/a>.<\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"
