How to select the right axial fan
Axial fans are the flat, high-flow fans used on the cooler and on the canopy of smaller machines. Two model families are stocked: YSWF for 380 V three-phase and YYWF for 220 V single-phase, in impeller sizes from 200 to 630 mm.
- Air flow — roughly 830 m³/h on the 200 mm size up to about 13,000 m³/h on the 630 mm size.
- Speed — the -2- models run at about 2300–2600 rpm, the -4- models at about 1350–1400 rpm, the -6- models at about 900 rpm.
- Noise — 45–78 dB(A); the 6-pole versions are the quiet ones and are what you fit when the machine stands in a working area.
- Certification — CE on the whole range, with the net weight listed per model.
Installation and maintenance
- Axial fans are sensitive to obstruction: keep at least one impeller diameter of free space in front of the guard, otherwise the flow collapses and the noise rises.
- Mount with the airflow arrow pointing the way the machine was designed. On a cooler the fan normally pulls air through the core and out of the canopy.
- Use the supplied mounting holes, not self-tapping screws into the shroud — a distorted ring rubs the blade tips.
- For single-phase models, check the capacitor value against the table; a wrong capacitor overheats the winding.
Axial fan FAQ
What is the difference between the YSWF and the YYWF models?
YSWF is the 380 V three-phase version and YYWF is the 220 V single-phase version with a capacitor. Same impeller, different motor.
My fan is noisy after a service. What changed?
Usually the fan was refitted with a distorted shroud or too little clearance, or a 6-pole fan was replaced with a 4-pole one. Compare the model number on the old fan with the new one before blaming the bearing.
Can I fit a larger axial fan to get more cooling?
Only if the opening in the canopy is enlarged to match. A larger fan behind a small opening moves less air than the original and makes more noise.
