Understanding Pressure Washer PSI, GPM, and CU

What makes all of the best industrial pressure washers in Kansas City different from one another? The PSI and GPM. If you’re shopping around for Kansas City industrial cleaning equipment, these are two acronyms you’ll find on the tags of every pressure washer. PSI and GPM are very important features to understand before making your decision. Continue reading to learn more about understanding pressure washer PSI, GPM, and CU and what they mean when it comes to cleaning ability.

Understanding Pressure Washer PSI, GPM, and CU

What is PSI?

The PSI (Pounds per Square Inch) refers to how much water intensity a pressure washer can produce. Why is it important? The PSI is essentially the stripping force that is applied to the surface. For example, if you are using the best cleaning equipment rental in Kansas City from DSG to remove a thick layer of dirt on your farm machinery, the PSI is what is going to scrape it off.

 

What is GPM?

While PSI refers to the pressure, GPM (Gallons per Minute) refers to the rate of water that comes out from the pressure unit every minute. You can think of GPM as the rinsing power. The higher the GPM, the faster you can clean.

 

Numbers to Look For

Now that you know what PSI and GPM mean, it’s time to discuss what numbers to look for. When you are looking for the best industrial cleaning equipment in Kansas City, it’s essential to understand that the higher the PSI, the more damaging it can be to surfaces. The most effective PSI rate typically ranges from about 2,000 to 3,000. An effective GPM range for pressure washers is 2.2 to 10.

 

What is CU?

The cleaning unit (CU) is the spec you receive when you multiply PSI and GPM. Doing so will give you a decent idea of the cleaning power of a pressure washer. However, it’s important to understand that the CU isn’t the only thing you should pay attention to.

For example, if one Kansas City cleaning equipment rental has a PSI of 3,000 and a 2.0 GPM, the CU would be 6,000. On the other hand, if another pressure washer has a PSI of 2,000 and a GPM of 3.0, the CU would be 6,000 as well. However, the second pressure washer would have a better rinsing power, while the first has a higher stripping power.
