AirScape 3.1S WHF Whole House Fan
The AirScape 3.1 delivers the same great combination of high power, low noise and robust engineering as the 1.7, but in a higher flow package. 3100 CFM, single speed unit.
Key features include automatic insulated doors and ultra low noise (51.5 dBA at 1m). Three year warranty. The on/off switch is customer supplied but we do include the white aluminum cube-core grille. This unit is not compatible with current remote controls since its single speed.
