  1. Reduce heat stress and improve air quality with Schaefer's uniquely designed circulation fans. These fans are engineered to produce greater air movement and superior cooling no matter the application. Also known as Horizontal Air Flow (HAF) fans, these fans move air in a coherent horizontal pattern creating a gentle "racetrack" airflow pattern needed in greenhouses to maximize heat distribution and humidity control by mixing the air, from ceiling to floor. Deep guard design for unmatched performance, low noise levels and safety without sacrificing airflow. Matching high-quality motors and blades for maximum efficiency. Powder-coated steel guards and bracket for increased durability and corrosion resistance. Comes with 5 ft 120 V power cord wired. 8" Fan. Learn More

As a general rule we recommend 200 CFM worth of airflow per 1000 watts of HID lights at a minimum. Don't know what CFM (cubic feet per minute) inline fan you need to exhaust your HPS or MH light? Read our guide on how to find the right CFM fan for your indoor grow room.
