Can Fan Inline Fans & Carbon Filters for Grow Room Ventilation
Can Fan has been manufacturing inline fans and ventilation products for grow room applications for nearly 30 years. Their range covers every stage of grow room air management — high-efficiency inline fans to move air through your ventilation system, carbon filters to neutralize odors from exhaust air, and the supporting components to connect and control them.
Can Fan Inline Fan Lines: Max-Fan, Q-Max & Max-Pro
Can Fan inline fans are designed for continuous operation in grow room ventilation systems. The Can Fan Max-Fan Series provides high airflow output at standard efficiency — a reliable workhorse for standard grow room exhaust and intake setups. The Q-Max Series offers a quieter operating profile through optimized fan blade geometry, suitable for noise-sensitive locations. The Max-Pro Series is Can Fan’s top-tier model — higher efficiency, more powerful output, lower noise, and three-speed control for variable airflow management. All Can Fan inline fans pair with compatible carbon filters for odor control in exhaust applications, and with fan speed controllers for variable operation. For accurate ventilation sizing, use our Ventilation & Carbon Filter Sizing Calculator to determine required CFM based on your room volume, ducting configuration, and carbon filter pressure drop.
Can Fan Carbon Filters
Can Fan carbon exhaust filters are packed with activated Australian RC412 carbon — one of the highest-surface-area carbon types available for odor neutralization. Filters are available in standard diameters (4 inch through 12 inch) to match inline fan sizes. Pairing a carbon filter with your Can Fan inline fan on the exhaust side of your ventilation system neutralizes odors before exhaust air exits the grow space. Intake filters keep contaminants, insects, and dust from entering through air intake ports — an underused but valuable addition to any sealed grow room intake system.
Ventilation Components: Ducting, Flanges & Speed Controllers
Hydrobuilder stocks Can Fan replacement pre-filters (to extend carbon filter service life), flexible ducting in standard diameters, duct couplers, flanges, and fan speed controllers including the Can-Trol and Vari-Voltage models. Fan speed controllers allow airflow rate adjustment based on room conditions — reducing fan speed during lights-off periods to maintain appropriate nighttime temperature and humidity without over-ventilating the space.
