Continuous product development may give rise to specification changes without notice.
Cleaning
• Remove dust by carefully vacuum cleaning using a soft brush.
• In the event of stubborn and heavy-duty dirt, the rotor can be sprayed with a
mild, alkaline detergent.
• Compressed air at low pressure (max. 6 bar) can be used for blowing the
surfaces clean. To avoid damage, the nozzle should not be held any closer
to the rotor than 5–10 mm.
A hygroscopic rotor variant can absorb particles which in some cases give off
odours. To prevent odours arising, exercise run the hygroscopic rotor using the
integrated control function. If an odour persists, we recommend cleaning the ro-
tor with a mild, alkaline detergent.
For cleaning it is recommended that the purge sector is fully open and the rota-
tional speed is 8 RPM. This assists with the sucking through of the detergent.
Post-rinsing is not normally required.
Lubrication
The bearings and drive motor are permanently lubricated and do not require ad-
ditional lubrication.
