15. LIFETIME AND DISPOSAL
15.2. Decommissioning and disposal
When disassembling, parts under voltage are exposed, which can lead to electric shock when touched.
Before dismantling, disconnect the fan from all poles of the mains and secure against being switched
on again!
Parts and components of the device that have reached their lifetime, e.g. due to wear, corrosion, mechanical stress,
fatigue and/or all other, not directly recognizable effects, must be disposed of professionally and properly after disas-
sembly in accordance with national and international laws and regulations. The same applies to excipients in use such
as oils and fats or other substances. The conscious or unconscious reuse of used components such as e.g. impellers,
rolling bearings, motors. etc. can lead to a risk to persons, the environment as well as machinery and equipment. The
applicable local operating regulations must be observed and applied.
15.1. Product life
15.3. Spare parts (motor + impeller)
Only original spare parts may be used.
The repair may only be carried out by personnel trained and authorized.
The motors are equipped with maintenance-free, permanently lubricated ball bearings. Under normal operating condi-
tions, the expected lifetime is about 30,000 operating hours.
The information given here depends strongly on the respective field of application as well as the environmental condi-
tions. We recommend replacing these fans after reaching about 30,000 operating hours or 5 years.
