A compact 1 ft × 1 ft intake + exhaust fan set — the residential-scale version of our shutter-mounted fans. Sized for high tunnels, hoop houses, Quonsets, and backyard greenhouses, the matched pair pulls fresh air in one end wall and pushes hot, stale air out the other to keep temperature and humidity in check. Ships as a set of two (one intake, one exhaust) with gravity shutters.
