Atlas Copco 1630060421 Fan Radial Compressor Spare Parts
Genuine original cooling fan and centrifugal blower components ready for immediate delivery.
Product Overview
The cooling fan and centrifugal blower serve as essential heat removal components in Atlas Copco oil injected screw compressors. These critical parts maintain optimal temperatures for aftercooler, oil cooler, and VSD inverter cooling systems by ensuring adequate airflow through the compressor canopy.
Critical Performance Note
Reduced airflow doesn't trigger immediate alarms but causes gradual temperature increases that reach shutdown thresholds during high ambient conditions or peak loads, potentially causing damage before detection.
Technical Specifications
- Centrifugal blowers generate higher static pressure than axial fans
- Specifically designed for canopy configurations with restricted internal ductwork
- Precision-matched impeller geometry, motor speed, and power ratings
- Optimized for specific cooling circuit pressure drop requirements
Important: Replacement motors with similar power but different speed ratings will not reproduce original airflow performance, even with compatible mounting positions.
Failure Indicators & Maintenance
Fan and blower motor failures typically manifest as intermittent noise or elevated afternoon temperatures before complete failure occurs. Early replacement based on confirmed diagnosis significantly reduces costs compared to secondary damage from in-service impeller or bearing failures.

Frequently Asked Questions
Q: Our compressor shuts down on high temperature in the afternoon but runs normally in the morning. Coolers have been recently cleaned. Where should we look?
Check the fan inlet grille for dust accumulation restricting airflow, verify hot exhaust air is not recirculating back to the canopy inlet due to installation layout, and measure cooling fan motor current against the nameplate rating. A motor drawing below rated current at full voltage is running below design speed. If all three are normal, log discharge temperature against ambient through the day to determine whether the rise tracks ambient linearly or accelerates, which distinguishes a capacity shortfall from a recirculation problem.
Q: The centrifugal blower is making intermittent noise that was not present previously. What should we investigate?
Three developing conditions produce this pattern: impeller imbalance from blade erosion or debris ingestion, motor bearing wear producing noise at specific speeds, and loose impeller attachment causing contact noise at the casing during speed changes. Isolate whether the noise occurs at constant speed, on acceleration, or at load changes to distinguish bearing degradation from impeller issues. Do not continue operating with progressive noise development; bearing failure or impeller separation in service causes cooler and canopy damage that exceeds the cost of a planned replacement.
Q: A locally sourced replacement motor matches the frame size and power rating but has a higher rated speed. Will this work?
No. A higher speed motor on the same impeller draws excess current, risks tripping motor protection, accelerates impeller fatigue, and increases acoustic output above the compressor's rated specification. In balanced multi-cooler canopy designs it can also reduce overall cooling effectiveness by disrupting airflow distribution. Match the original speed specification, not only the frame size and power rating.
