#5 in Roof mountFull review
A well equipped hybrid roof fan with a long warranty at a mid range price, for medium attics. Buy the 301A, which includes the night adapter for the same price as the 301.

#7 in Roof mountFull review
For a medium attic on a roof that faces away from the sun, where the tilting panel earns its keep. On a south facing roof the 25 W model is better value.
