The Plantalytix AIR VK EC 250 is a heavy-duty inline fan designed for large-scale grow operations that need precision ventilation over extended ducting. With a 250mm duct diameter and a high-efficiency EC motor, it gives you full speed control through 0–10V or PWM signal — meaning it’s easy to dial in exact airflow for any stage of plant growth. Equipped with a mixed-flow impeller and aerodynamic design, it helps maintain high static pressure performance, making it ideal for use with long duct systems, carbon filters, and silencers. Its impact-resistant, noise-reducing plastic housing is durable and discreet, while its sealed ball bearings ensure an extended lifespan life with minimal maintenance. This is a top-tier choice for experienced growers managing heat, humidity, and odor in high-output setups. For medium-sized setups, the AIR VK EC 200 is a scaled-down option. For smaller grows with EC control, check out the AIR TT PRO EC 150.
