## Questions & Answers

**Q: Is my fan defective? For such a small fan it is extremely loud.**
A: Use light weight clipper oil on the moter behind fan blades, also use tape to hold to pieces together after twisting back together. I own three need to add oil to all. All have been running non stop for over 6 months.

**Q: Can you attach a variable speed controller to this**
A: You can, however, with just 200 CFM of air movement you may want to just keep it on full. The motor will make more humming noise if you use a speed controller to decrease speed.  I found it makes less noise on full than it does if you decrease the speed which increases motor hum noise considerably.

**Q: If i use this fan as my exhaust fan for my 3ft×3ft×6ft grow tent, and use the cheaper less powerful 100cfm as an inline fan would that suffice?**
A: Hey man i dont know where you live? But im in new england and heat is usaully temporary problem for a few months. But the 4 in didnt cut it i ended up buying the 6 inch kit with carbon filter and still have the 4 inch. This year is brutal and glad i switched in april. Honestly i would get the 6 or even the 8 with adjustable speed. I struggled to justify the costs myself but its gonna save money down the line and You  will have room for lose of efficency with bends and dirty blades. But hey everyone journey is different. Its just cheaper to go bigger then at the minimum CFM or btu or any hvac project. It wont work as hard and run hard at 100% power

**Q: Does this have a brushless motor? Need to minimize spark chances internally.**
A: Yes it has a brushless motor
