5.1 Vibration testing

Checking of fan for mechanical vibration based on ISO 14694.

Recommendation: Every 6 months. Max. vibration severity is 3.5 mm/

s, measured at the motor fastening diameter on the motor support plate in

the direction of the motor axis of rotation and perpendicular to this.

Fig. 1: Example illustrating vibration measurement. The arrangement of

the sensors depends on the device concerned and the installation

situation.

5.2 Cleaning

To ensure a long service life, check the fans regularly for proper

operation and soiling. The frequency of checking is to be adapted

accordingly depending on the degree of soiling.

; Dirt deposits on the motor housing can cause overheating of the motor.

; Soiling of the impeller can cause vibration that will shorten the service

life of the fan.

; Severe vibration can destroy the fan.

; In such cases, switch off the fan immediately and clean it.
