The Helios VARD 315/4 is a high-pressure pipe fan designed for efficient air movement in ducted ventilation systems. Its cylindrical housing is made from galvanized sheet steel and includes flanges on both ends, following the DIN 24155 hole pattern for secure and standard installation. A built-in guide wheel helps optimize airflow and system performance.
The fan features a semi-axial impeller with eight spatially curved blades made of durable thermoplastic, offering reliable and energy-efficient operation. The unit is directly driven, providing consistent performance and reduced maintenance for high-pressure ventilation tasks.
