with dust (e.g. if it has been running without inlet air filter) it can cleaned by
vacuum cleaner or low pressure compressed air.
Heater Bank:
The PTC heater bank is maintenance free however, if it becomes blocked
with dust (e.g. if it has been running without inlet air filter) it can cleaned by
vacuum cleaner or low pressure compressed air.
Desiccant Rotor Drive:
The desiccant rotor is driven by a geared
motor via a toothed belt. The rotation
speed is approximately 20RPM. It can be
seen turning during operation through
the air outlet duct,
Over-Heat Protector:
