The diagram below outlines the basic operation of vacuum motors used by Mytee. 


A vacuum motor has vacuum chambers (or stages). Each stage is a fan in a sealed compartment.

You can usually tell how many stages a vacuum has by counting the number of chambers.

Chambers make up the bottom portion of the vacuum motor and resemble layers of a cake. The

more stages a vacuum has, the more powerful the suction.

The fans in the chambers produce suction on the intake side of the vacuum, and then exhaust on

the outlet side. The fan will either exhaust through the side vents (peripheral) or through a horn on

the side of the motor (tangential).

The suction side of the vacuum is used to produce suction for extraction. On janitorial units, the

exhaust is usually just routed out of the bottom or the rear of the machine. On automotive units, the

exhaust can be used for drying.

IMPORTANT: To avoid damage to the vacuum motor, DO NOT dry vacuum with your extractor. Dry

vacuuming may cause debris to be sucked into the vacuum motor chamber and the vacuum motor

will need to be replaced.
