Solid performance, slightly noisy
The build quality is robust and the metal housing feels durable. It moves a lot of air as advertised. The only downside is that it is a bit louder than expected at full speed, but acceptable for an industrial setting.

Great value for dust extraction
I hooked this up to my woodworking cyclone separator, and it works flawlessly. The static pressure is sufficient to pull fine dust through the ducting without clogging. Highly recommend for hobbyist shops.

Good specs, check your voltage
The fan performs exactly as described in the specs. Just make sure you order the correct voltage configuration for your region. I had to swap the wiring for 220V, but the instructions were clear enough.

Perfect for my workshop spray booth
This fan provides excellent suction for my small automotive paint booth. The airflow is consistent, and it handles the fumes much better than my previous axial fan. Installation was straightforward with the provided mounting holes.

Reliable induced draft solution
We use these units for general ventilation in our manufacturing line. They have been running 8 hours a day for three months with zero issues. The motor stays cool even under continuous load.

Exceeded expectations
Fast shipping from Chengdu and well-packaged. The fan is powerful enough to clear smoke from our welding station quickly. Very satisfied with this purchase for the price point.
Q: Does this fan come with a power cord and plug?
A: No, this industrial unit is typically sold without a plug to allow for hardwiring into your specific electrical setup. A junction box is included on the motor housing.
Q: Can this handle hot air up to 80 degrees Celsius?
A: The standard model is designed for ambient temperatures up to 60°C. For continuous operation with air hotter than that, please contact us for a high-temperature bearing variant.
Q: What is the diameter of the inlet and outlet flanges?
A: Both the inlet and outlet flanges have a diameter of 200mm, which is standard for the 2.8A series. You can easily adapt this to square or rectangular ducting with a transition piece.
Q: Do you offer a warranty for international shipments?
A: Yes, all units come with a 12-month manufacturer warranty covering motor defects and structural failures. We provide spare parts support globally.
Q: Is the impeller made of aluminum or steel?
A: The impeller is constructed from high-grade aluminum alloy to reduce rotational mass and improve energy efficiency, while the housing is made of cold-rolled steel.
