Helios round duct fans offer versatile system solutions for a wide range of requirements, with a broad choice of models and coordinated accessories. The range includes the particularly slim SlimVent series, silenced versions in the AcousticLine series and the highly adaptable MultiVent. All series are also available with EC technology for efficient, demand-based operation.
Ventilation of small to medium-sized rooms with extremely small dimensions and installation in any position. MultiVent is available in AC and energy-saving EC version.
Linear flow pattern and impressive performance characteristics with simple installation. Extremely quiet operation and optionally available with energy-saving EC technology.
Explosion-proof InlineVent round duct fans comply with directive 2014/34/EU (ATEX) and they are suitable for conveying smaller volume flows in rooms with explosive atmospheres.
Barely higher than the duct diameter for compact installation in any position – also in silenced version. Longer duct sections are not a restriction due to the high pressure rates.
Silenced centrifugal round duct fans with high volume output and pressure performance for extract air and intake air systems. Also available as SilentBox EC for high energy efficiency.
Multifunctional unit for conveying medium to high volume flows against high resistances in ventilation systems. Variable adaptation to structural conditions is possible.
Particularly suitable for conveying contaminated, humid and hot air up to max. 120 °C. Also available with EC technology.
Centrifugal fan for conveying dirty, greasy, hot and humid air against high resistances. Also ideal as an extract air fan for extraction hoods in commercial kitchens.
Centrifugal fan for conveying explosive gas, vapour and air mixtures. The motor-impeller unit is retractable and the motor is located outside of the air flow.
