A lot of suction.

The recommended replacement motor was larger in diameter than my original OEM motor (7.2rdquo vs 5.7rdquo), but ii did fit, with some minor modifications to the screen enclosure that is installed over the motor. The motor works fine, and seems to have the same suction capability and noise level as the original OEM motor.

The central vac assembly is now in place, operating just fine, and my wife is happy.

We do not have any alternate motors listed for your model #. There are several variables to consider when choosing a motor for your unit including height, diameter, amperage. You will want to contact the manufacturer direct for any alternate motors they recommend. We recommend using the original motor in this unit. Thank you.
