Question 1

Is the 10" thickness the minimum, or can it be trimmed down?

Accepted Answer

When installed as directed--with all components unaltered--the minimum thickness is 9 inches. However, as other have indicated, you can reduce this further by trimming the metal components of the duct. In fact, if you managed to glue/seal the fan housing directly to the plastic vent cap, the whole assembly requires only 5 inches. So there are a lot of options to put this unit in a thinner wall.  If you trim the duct work, just be sure you have means to tape/seal everything once it is in the wall. On the final step, the length of the flexible duct is what enables you to tape/seal all the connections on the exterior side before compressing everything back into the wall.

Question 2

Can this be left on 24 hours/day in a utility closet?

Accepted Answer

Indefinitely, I am not sure, but it does run here in 100 degree+ temps for most of the 24 hour day and has done so for about 4 years. If the temps are not too high it might be like one of those machines that if it runs all the time it will go until the bearings go out after a bunch of years.

Question 3

Is it loud?  Can you have a conversation In front of it?

Accepted Answer

It's not very loud, yes you could have a conversation near it. Had to do a small adjustment to free the fan, due to repacking from a previous customer.

Question 4

Can i buy the outside 8x8 louvered cover separately? the one i have failed after 3 years. the fan still works fine.

Accepted Answer

Yes you can, Lowe's and Home Depot carry them, you might have to modify the mounting holes but yes that should work.
