Our exhaust fans are ideal for cooling and providing fresh air inside a greenhouse, shop, or garage. They include a rustproof aluminum shutter frame with built-in interlocking louvers to reduce heat loss during cold months. These exhaust fans also come equipped with completely enclosed variable speed direct drive motors which can be adjusted from 100% to ~35% of CFM if one of our optional fan speed controls is added. This allows you to reduce fan speed during cold months minimizing cold air shock to plants. Fans only run at maximum speed without a speed control. Simply add intake shutters and any of our automated controls, and you will have all you need to equip your greenhouse or shop with a durable fully automated ventilation system.
