The Atlas Copco Fan Radial ZT75 (part no. 1630-0604-12) is a genuine cooling fan for the ZT75 oil-free screw compressor, superseding six earlier part numbers (1622364622, 1613948902, 1622393722, 1623254002, 1625595114, 1625837101). At 90 kg, this is one of the larger and higher-value fans we supply, consistent with the cooling demands of a large-frame stationary compressor.

Progressive Failure,Abrupt Shutdown
Why a Failing Fan Often Shows Up as a Sudden Shutdown
Cooling fans typically fail gradually — bearing wear increases friction and noise before the motor eventually seizes or a blade becomes unbalanced — but the compressor ‘s protective response is often abrupt:
a thermal shutdown once cooling capacity drops below what the system needs.If you ‘re seeing intermittent high temperature trips before a full failure,it ‘s worth inspecting the fan for unusual noise,vibration,or reduced airflow rather than waiting for a complete stoppage.
Electrical Draw as an Early Warning
Rising Current Draw Can Signal Troub le Before Failure
If your facility monitors motor current draw,a gradual increase on the fan circuit — without a corresponding change in ambient conditions — often indicates increasing mechanical resistance from bearing wear,well before the fan shows an obvious symptom.This is a more proactive way to catch a failing fan during scheduled maintenance,rather than discovering it during an unplanned shutdown.
Common Questions
How do I know if the fan is failing versus another cooling issue?
Unusual noise,vibration,or a noticeable drop in airflow near the fan are the most direct signs.If the compressor is overheating but the fan sounds and looks normal,the issue may lie elsewhere in the cooling system (e.g.,a blocked cooler or a failing thermostat).
Can I keep running the compressor with a noisy but still-working fan?
Short-term,yes,but the vibration from a failing fan can accelerate wear on surrounding components — we ‘d recommend replacing it at the next planned downtime rather than waiting for full failure.
How do I confirm the correct voltage/phase for my compressor?
Check your compressor ‘s electrical nameplate,or send us a photo of it and we ‘ll confirm the right match.
What payment methods do you accept?
T/T (bank transfer).
