No correct answers YET, although I will give a hint, Joseph is on the right track.
Although the anaconda might be close too.

It’s an inline fan Possible for removing Radon Gas from the under floor slab . Have never seen one we In Canada are not concerned with Radon. What is my prize.
It should have better support also

I will wait until tomorrow, but no-one has it exact yet. I will say that it is not Radon if that helps.

Booster fan for the bathroom exhaust ventilators.

Joe, you’re not a new guy, but nope. It is a booster fan; however, it is a booster fan for a high efficiency furnace. The run is approximately 50 feet from the basement through the roof penetration; so there is the fan in the unit which is in the basement and then this booster in the attic where it comes through the ceiling which pushes the exhaust through the roof. Not a typical installation here, they normally just put the intake & exhaust together.

What’s done on the intake side?

New to me is this approved.
I expect it gets it supply air from the home .
Would be interested in seeing the manufactures recomendation on this .
I still feel that there should have been some support on the fan .
Do you know voltage is the fan.

Supply air comes from the outside of the basement on a gooseneck shaped pvc pipe, I think 2 1/2", but I don’t remember. That is a standard set up for it, but normally there is a discharge pipe right beside it facing with a gooseneck going up and the intake goes down. This is the first one I have seen where they did not put the exhaust in the same general area as the intake.
Fan is 110 volt wired to a junction about 10 feet away.

This additional vent is not approved by any manufacture that I am aware of. A few of the issues created with the additional fan are:
1)The fan will pull more combustion air through the heat exchanger then designed, this can cause improper combustion, poor operating efficiency.
2)Inducer vented furnaces are equipped with a air draft switch that shuts down the furnace if the venting fails, this additional fan can override this safety device creating a dangerous non AGA approved installation.

John; Sounds good to me, I thought it was an inline booster fan for a dryer. I guess everyone except me noticed improper support. ha. ha.
I was about to comment the pipe is to small and why were PVC reducing couplings were not used instead of a reducing fernco coupling.
Good job. Only if you are correct. ha. ha.
