FAQ - Multifan (Motor - service/maintenance)

Frequently asked questions

Why do we need a plug on the motor? »»

Due to rain, condensation or wet cleaning water may enter the motor housing. By removing the plug at the lowest end you can get rid of the abundant water quantity. After the motor is wettened, let it run for a couple of hours. Due to the heat all the water is automatically evaporated and removed.

Where do we need to locate the motor plug? »»

To be able to remove the abundant water easily, the plug needs to be at the lowest point during mounting.

Do we need to remove the plug during wet cleaning? »»

It is always better to prevent water entering the motor. Remain the plug in, when cleaning. Vostermans Ventilation advises to remove the plug always after the cleaning. Periodically removing the plug is another option.

MOTOR REBUILD: Can the motor be rewound? »»

The motor can be rebuilt by using the same type wire, class F materials and the same number of windings. However, the rewind process is considered too expensive because of the heavy duty winding used in the Vostermans Ventilation motor. The new motor price is probably lower than the rebuild cost.

MOTOR DRAIN PLUGS: How are the motor drain plugs used? »»

Condensation, rain and wash water needs a way out of the motor. The red plug on the motor cap is a drain plug. The Multifan motor also has a drain hole in the front of the motor (behind the impeller). In a normal vertical fan position, the front hole serves as the drain since it is the lowest point on the motor. If the fan is mounted horizontally to a surface, with the motor at the bottom, the motor cap is the lowest point, so the plug should be removed from the cap for proper drainage. The red plug should then be installed in the front hole position.

MOTOR MOUNTING POSITION: Can the Vostermans Ventilation fan be mounted in either vertical or horizontal position? »»

Yes, due to the balanced design it can be vertical, horizontal, or any angle in between. This is one advantage of using ball bearing support on the rotor instead of lower cost sleeve bearings.
