For maximum air exchange and carbon dioxide replenishment, a shutter fan is ideal. The versatile shutter fan can be used alone (relying on the intake of the automatic vents) or together with a shutter or motorized intake to create cross ventilation. A motorized intake shutter opens more fully and provides an effective seal against outside air when closed. Very easy to set-up, just wire to thermostat or timer.
Features:
- Redwood framing
- Pigtail power cord for the fan or motorized shutter
- 760 cubic feet per minute rating.
