RadonAway 23005-1 GP501 Radon Mitigation Fan, 3"

What is the cfm on a GP201 fan?

our levels were 4-8 and just installed the GP501. How long would you think it normally takes the levels to go down - 1 day - 1 week? thanks.

is this product listed by UL ?

Is this a complete package? do i need to buy any other parts to install? it's a new home and the builder i have a 3" venting pipe and an outlet.
