Systemair Prio® 250EC Inline Duct Fan

Application The prio Air series is designed for installation in ducts. Extremely efficient, prio Air fans are perfect for a wide assortment of powerful, quiet air-moving applications. Design Compact size, low noise, very high efficiency and air tight casing. Aerodynamically optimized impellers and guide vanes with integrated external rotor motors. Includes a mounting bracket. Special composite material is corrosion-proof and light weight. Speed control The prio Air EC fan motor's speed is controlled via a 0-10Vdc signal. The motor provides a +10V reference that can be used by a remotely-mounted potentiometer (such as MTP 10). The motor can also be controlled by an externally-provided 0-10Vdc signal that can come from any device or a Building Management System (BMS). The fan's motor also provides operational speed (tachometer pulse) output that can be used to verify fan operation. These control features allow the prio Air EC to be integrated into and play an active role in smart HVAC systems in buildings. M...
