Review: Failed after 5 months - Seller has a 2 year warranty , poof seller is gone from desertcart, so is the warranty. desertcart sorry you are out of luck.
Review: Very nice, quality, made to last - 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.

## 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.
