The Helios Fans ITEC 150 is a durable twin fan system engineered for duct-mounted ventilation where reliability and continuous operation are key. Constructed from corrosion-resistant galvanized steel, this unit provides 100% standby fan support with integrated duty-sharing via standard change-over panels. It offers convenient top or bottom access for maintenance, and the acoustically lined casing ensures quiet performance with minimal sound breakout. Wiring is simplified with a shared terminal box, and the fan speed is fully controllable using the Helios ACSW EC panel and PA10 potentiometer. Installation is quick and secure thanks to standard side mounting rails, making the ITEC 150 ideal for commercial and industrial ventilation setups.
