Review: Works well, does what it's supposed to. - I bought my unit for ventilating a basement. After about 2 months of continuous use, it stopped working for seemingly no reason. It was past desertcart's return period, so I contacted Turbro's support. They sent me a new unit the very next day! I'm back up and running no problem. this thing can move a TON of air. And while it's not super quiet at the max speed, it's very reasonable. I keep it at a relatively slow speed, so it's pretty dang quiet for me. As long as this replacement unit holds up, I'll keep this as a 5 star review. If the new one dies like the old one did, I will likely update it.
Review: Very pleased - Very pleased. Have installed a handful of these, and everyone is happy. Very quiet. An above-standard system.

## Questions & Answers

**Q: How far can the air be pushed  from one room to another**
A: It’s 195 CFM. depends on the duct work.   Go bigger and get the speed control. It’s a good quality fan.

**Q: How far for the fan unit can the speed control be mounted?**
A: Hi thank you for your inquiry. This speed control comes with a 16 ft cable, and it could be mounted away from the fan not more than 16 ft.  
Should you have any further question, please kindly contact us by support@turbro.com.

**Q: Can this dc power motor be adapted to be driven from a dc power source?**
A: This unit operates at 110vac input.  What DC voltage did you have in mind. I think that this motor operates at a higher voltage that would not make DC practical.

**Q: Is the fan reversible?**
A: No. The unit is single direction.

### ⭐⭐⭐⭐⭐ Very pleased
*by T***B on March 22, 2026*

Very pleased. Have installed a handful of these, and everyone is happy. Very quiet. An above-standard system.

### ⭐⭐⭐⭐⭐ Very nice, quality, made to last
*by J***E on July 31, 2021*

Really powerful little fan. It’s made of sturdy metal and feels like it’s made to last. The settings run 1-100 and it’s very sensitive/responsive when turning up or down. When on full blast it can get loud but that’s because it outputs air like a jet engine. You can probably find cheaper fans that are similar size but this one is probably the best quality you’re going to find.
