Helios Fans ITEC 355

The Helios Fans ITEC 355 is designed for reliable twin fan operation with a 100% standby feature to ensure uninterrupted airflow in duct systems. The robust galvanized steel casing provides excellent corrosion resistance, ideal for long-lasting performance in various environments. Maintenance is facilitated by an access panel that can be positioned either on the top or bottom of the unit. Equipped with standard change-over panels and a duty-sharing option, the system balances fan usage and simplifies wiring via a common terminal box. Acoustic lining effectively reduces operational noise and sound breakout for quieter ventilation. Installation is straightforward with standard side mounting rails, while speed adjustments are easily managed using the Helios ACSW EC change-over panel combined with the PA10 potentiometer speed controller, delivering an energy-efficient and user-friendly solution.
