free-standingcommercialindoor

Twin Centrifugal Box Fan • 7 standard sizes from 125mm to 500mm • Air volume flow rates up to 1.740 m3/s • Static pressures up to 730 Pa • Suitable for operating temperatures up to +60°C • Redesigned casing to improve airflow and reduce specific fan powers • Auto Changeover Panel Included • Acoustically lined internally to reduce breakout noise levels • Low Specific Fan Powers • Configurable with optional spigot type • Available in EC Twinflow STDL fans are suitable for external mounting. The range incorporates advanced backward curved impellers. Features and Benefits Easy Installation All models are designed for direct connection to standard diameter flexible or rigid circular ducting with long spigots. Easy Commissioning Integrated commissioning control allows single speed selection and also limits maximum speed if used with an external potentiometer. Efficient Performance High efficiency low tonal noise backward curved centrifugal impellers are directly driven by an EC external rotor motor, provide low specific fan powers and stepless speed control without tonal noise generation. Controllability EC motors provide precise speed control via potentiometer or BMS. Reduced fan speeds can provide significant cost-savings through lower energy consumption in both mechanical energy of motors and also on the conditioning of replacement air. Warranty Each STDL has a 12 month warranty.
