Maintenance

Danger! The replacement of turbines or electrical components may only
be carried out through authorized specialist personnel or by the TBH
Service! Units with continuous-rotor motors are maintenance-free.
TBH extraction and filter systems are offered with four different motor concepts.
•
Brush-type motors (only BF 9)
•
EC brushless turbines
•
EC brushless blowers
•
IEC ATEX motor (only DT series)
The brush-type turbine is used wherever a cost-efficient solution is required and the daily
operating time of the system is rather short.
Brushless turbines are the most common motors. They provide maintenance-free continuous
operation and high vacuum at reasonable costs.
EC brushless blowers provide high air capacity at low energy consumption and low noise
emissions.
10.1

Maintenance of Motors

For filter units with brush-type motor, it must be replaced after approx. 600-1000 operating
hours (the maximum operating hours that can be achieved vary depending on the
application). This is shown by the automatic shut-off of the turbine. A message is not shown
on the display.
All other TBH engine concepts are 100% maintenance-free.

Cleaning the Unit

Caution! For cleaning of the unit, appropriate protective equipment must
be worn to avoid contamination with substances that may be hazardous
to health.
•
Before cleaning, the unit must always be switched off and the mains plug removed.
•
The unit's housing is coated with a resistant varnish. A damp cloth and a household
cleaning agent are sufficient for cleaning.
•
Do not use solvents!
Units of the CR series or standard systems in stainless steel can also be cleaned with
disinfectant and alcohol in accordance with the specified cleaning instructions.
•
Pay attention that cleaning water does not enter into the electrical parts and the
ventilation slots.
•
When loosening filter modules to clean the system, make sure that the seals are
not damaged and that the seals fit properly when the system is put back into
operation.
•
Dry everything well with a cloth.
