What is G factor?

When looking at washer extractors, the G Factor is one of the more important items you should compare. RPM is a figure that is usually compared, but this is only relevant if compared also to the diameter of the drum. G Factor is calculated by the following formula:

G = (5.6 X RPM² X D)/1,000,000

The following example is a washing machine with a drum diameter of 70cm and RPM of 1,080

(5.6 X 1080² X 70)/1,000,000 = 457 G Factor

The higher the G factor the higher the moisture removal. This is important as it means less time in the dryer which means energy savings.
