The Can-Filter Max-Fan 6" 334 CFM is a solid, dependable choice for small to mid-sized grow rooms that require steady airflow to keep plants healthy. Energy efficient with a mixed-flow design, it delivers 334 CFM of ventilation but uses less power and makes less noise than traditional inline fans. It’s perfect for 3x3ft to 4x4ft tents or smaller grow rooms where managing heat, humidity, and fresh air exchange is needed to prevent mold, pests, and stress. If you’re looking for a fan with a bit more output, the Max-Fan Pro Series 6" 420 CFM steps things up with more airflow and additional features. For growers who need a little more power, the Max-Fan 8" 667 CFM delivers without a huge jump in size.
