The ProFan Axial Inline Fan 150mm is the powerhouse of GardenHighPro’s vent fan lineup — designed for larger grow rooms and commercial setups that demand strong, reliable airflow. With its impressive max airflow of up to 330CFM, this fan regulates temperature and humidity to help create the ideal environment for thriving cannabis plants. With a quiet operation of around 44dBA, it reduces excess noise, while its energy-efficient motor consumes just 45kw per hour — perfectly balancing performance and operating cost. Its durable, corrosion-resistant housing ensures it runs strong grow after grow, making it a long-lasting investment for serious growers.
