WHAT’S THE DIFFERENCE BETWEEN BRUSHED AND BRUSHLESS MOTORS?
Brushless blower motors have a higher capacity to move air than brushed motors however do so with less static pressure. Static pressure can be thought of as suction and is measured in inches of water column (wc.). Thus a low suction unit will pull water perhaps 2 inches up a pipe and no more and thus would have a static pressure of 2″wc. High power brushless motors have a maximum measurement of 44″wc.
