Centrifugal in-line fans – InlineVent
– In principle, the units are maintenance-free, there are no user maintenance provisions.
Nevertheless, all necessary maintenance work must be carried out by qualified electricians!
– Excessive deposits of dirt, dust, grease, etc. on the impeller, motor, protection guard and, above all, between the
housing and the impeller, are not permitted, as these can lead to an unbalance in the impeller, overheating of the
motor or the blocking of the impeller. In such cases, the unit must be cleaned
– In cases of longer periods of standstill, maintenance must be carried out when the unit is restarted.
– In case of standstill or storage for more than 2 years, the motors must be replaced.
The following must be checked:
• Secure attachment of the fan to the subsurface / system, replace in case of doubt
• Remove contaminant deposits
• Mechanical damage, disconnect unit, replace damaged parts
• Tight fit of screw connections, do not loosen screws in the process!
• Casing quality (cracks, brittleness of the plastic)
• Free movement of the impeller, impeller does not move freely, see Fault causes 8.2
Wear protective gloves when checking unhindered running of impeller!
• Bearing noises
• Vibrations – see Fault causes 8.2
• Current consumption according to type plate – see Fault causes 8.2
8.1

Cleaning

An insulation/installation fault may result in electric shock!
Before cleaning, isolate the fan from the mains power supply and protect against being switching on again!
The unexpected rotating impeller can crush fingers.
Before cleaning, isolate the fan from the mains power supply and protect against being switching on again!
– Clean casing and impeller with a damp cloth
– The motor must not come into contact with water!
– Do not use aggressive cleaning agents that could damage the paintwork!
– High pressure cleaners or water jets are not permitted!

Fault causes

Fault Causes
Fan does not start – No voltage
– Impeller blocked
– Motor blocked
Fan does not turn – Mains voltage failure
(no longer turns)
– Thermal contact (TK) has triggered Automatic restart after cooling. Check transport
– Fuse has tripped
– Impeller blocked or
Fuse has tripped – Shorted coil in motor
– Supply line or connection
– Connected incorrectly
Vibrations – Contamination
– Attachment-related resonance
Abnormal noises – Grinding impeller
– Bearing damage
– Mechanical damage
Fan no longer perfor- – Insufficient air delivery
ming (speed)
– Incorrect voltage
– Bearing damage
– Contamination
– Insufficient backflow

Standstill and disposal

WARNING
When dismantling, live parts can be exposed, which can result in electric shock if touched. Before dismant-
ling, isolate the unit from the mains power supply and protect against being switching on again!
Parts and components of the fan, whose service life has expired, e.g. due to wear and tear, corrosion, mechanical load,
fatigue and/or other effects that cannot be directly discerned, must be disposed of expertly and properly after disas-
sembly in accordance with the national and international laws and regulations. The same also applies to auxiliary mate-
rials in use. Such as oils and greases or other substances. The intended and unintended further use of worn parts, e.g.
impellers, rolling bearings, filters, etc. can result in danger to persons, the environment as well as machines and
systems. The corresponding operator guidelines applicable on-site must be observed and used.
