We've been getting a lot of interest form lab guys who need consistent airflow for drying setups or fume extraction, and what it does is push a solid 520 CFM at 0.3 m³/s volume—enough to clear a small chamber pretty fast, and the 21V 450W motor handles sustained runs without bogging down.
The stepless speed control is actually the key here because you can dial it from a whisper to full blast, and most buyers go with brushless option for longer life in daily use, though the brushed motor is cheaper if you're prototyping and don't mind swapping brushes every six months or so.
It's listed for experiment use, so don't expect it to survive a drop onto concrete—the plastic housing is fine for bench work but won't take abuse like a metal-cased unit, and the axial flow design means it's better at pushing air in a straight line than pulling from tight corners.
We usually have stock on the blue ones with brushed motors, but the brushless version takes about 20 days or so because they're made to order, and MOQ is typically 10 units for the factory wholsale price—confirm lead time if you need RoHS or CE certs on the batch.
One thing you wouldn't think to ask is that the 46*23*23cm box doesn't include a battery or charger, so you'll need a compatiible 21V pack or a separate power supply for bench use, and the no-load speed of 28,000 RPM drops off pretty quickly under load (roughly 15-20% depending on the fan attachment).
The brushed motor is more affordable and works fine for standard use, while the brushless motor gives you longer runtime and higher efficiency — less heat and maintenance. You can choose whichever fits your budget and job demands.
Yes, we fully support customization — you can change the color, add your logo, or adjust the packaging. Just let us know the details when you place the order.
It's certified with RoHS and CE, so it's fully compliant for EU import and sale. We provide the certificate copies with each shipment.
MOQ is usually 100 units for standard specs, but we can negotiate for smaller trial orders. Lead time is around 15-25 working days depending on the customization level.
The stepless trigger lets you adjust the speed smoothly from zero to max, so you can dial in exactly what you need. Yes, it's built for experiment use — just keep it within the 450W rating and it'll run continuously without issues.
Shipping speed was simply spectacular. Sending this item from China to my location in Europe took less than a week, which surpassed all my expectations for international delivery. The packaging itself was secure and robust, showing no signs of damage whatsoever upon arrival. Such careful handling is always a significant plus. Regarding the product quality, it feels solid and well-constructed in hand. The materials used seem durable, and the overall finish is professional. I haven’t had a chance to test its full capabilities yet, but the initial impression based on build is very positive. The seller’s service was also satisfactory. Communication was clear, and they provided a tracking number promptly. Any pre-purchase questions I had were answered in a timely and helpful manner. Overall, this was a smooth transaction from start to finish. The combination of fast logistics, apparent high quality, and good customer support makes for a very positive purchasing experience. I would certainly consider ordering from this supplier again based on this interaction.
