The Max-Fan Pro Series 10" 1052 CFM is perfect for growers running medium to large scale grows that need consistent, reliable, controllable air exchange. Its high-efficiency mixed-flow impeller, sturdy German-engineered motor, and fiberglass composite housing delivers powerful 1052 CFM performance — running quiet and cool even under pressure. With a built-in 3-speed controller, you can dial in the perfect amount of airflow for your grow room’s unique climate needs — whether you’re venting a high-heat flowering space or maintaining fresh air in a sealed environment. If you’re looking for a more simple option, the Max-Fan 10" 1019 CFM offers similar power without all the bells and whistles. For growers that require whisper-quiet ventilation for discreet setups, the Q-Max 10" 1019 CFM adds acoustic insulation for ultra-quiet operation.
