5.1 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.
DANGER
Risk of injury from rotating fan.
→ Only clean when not in motion. Interrupt the power supply,
secure against renewed switch-on. Secure against start-up,
prevent air flow.
;
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.
;
The preferred method of cleaning is dry cleaning, e.g. using
compressed air.
;
Do not use aggressive cleaning agents!
;
Before cleaning, run the fan for an hour at min. 80% speed.
;
Check the tightness of the cable glands.
;
As is standard procedure for barn cleaning, the dried-on dirt first has to
be loosened by soaking. If the fans are not treated by the stationary
soaking installation in the barn, they have to be manually soaked
separately using a hosepipe or knapsack sprayer for example.
Instructions for cleaning
Fig. 5: Cleaning of the fan with a high-pressure cleaner.
;
Maximum water pressure 80 bar
;
Minimum clearance between water outlet and fan 40 cm
;
The water jet must be aimed perpendicularly to the blades.
;
If possible, only aim the water jet at the rotating parts.
;
Do not aim the water jet directly at the condensation drainage hole (if
applicable).
;
When cleaning the electronics housing, do not aim the water jet
directly at the terminal box cover or cable glands.
;
If there is a condensation drainage hole in the rotor, make sure this is
not blocked by dirt.
;
Completely remove any cleaning agents used.
;
If severe corrosion is visible on load-bearing or rotating parts, switch
off the device immediately and replace it.
;
Repair of load-bearing or rotating parts is not permitted!
;
Operate the fan for 2 hours at maximum speed so that any water that
has ingressed can evaporate.
;
If cleaning does not eliminate vibrations, the fan may need to be
rebalanced. To have it rebalanced, contact ebm-papst.
;
The fan is equipped with maintenance-free ball bearings. The lifetime
lubrication of the ball bearings is designed for a service life of 40,000
hours.
;
If bearing replacement is necessary after that period, contact ebm-
papst.
;
Adapt the maintenance intervals to the actual level of dust exposure.
