#1 Q:   Does the unit remove radon gas from basement area.
A:   Its a ventilation fan so it will dilute/replace any contaminated air (radon or other contaminants) with outdoor air. If you have radon in you house you should consider a dedicated sub-slab system to extract the radon before it gets into the house.

#2 Q:   Will this unit take care of a 1500 square. Ft. Damp basement Thanks
A:   Tjernlund does not rate it for a specific basement size since there are so many variables in terms of the moisture levels, exchanged air humidity and temperature, etc. Typically 1 is installed per typical home basement.

#5 Q:   how do the fans reverse? can one fan be run exhausting basement air while the other is pushing fresh air into basement?
A:   The fans pull out and are installed facing the other way...You can indeed have them running both ways at the same time. Makes it nice for areas where there is only one hole.
