yes there is a return air system inside the 2" pvc. I have the insulation, just haven't gotten to installing that nor the blower. it is 100% co2...would it be recommended to switch to 75 nitrogen 25 co2 mix with basically domestic ales and lagers? the beer line is cold right now (I keep the heat at 55 in the house and the basement is 45--Western Massachusetts is like 34 outside) so I'm not really losing anything even in the first pour, as long as pressure is about 25 psi.
