Prices & Options
The Helios VARD 355÷4÷2 is a high-performance in-line mixed-flow fan engineered for high-pressure ducted ventilation systems. The cylindrical housing is made from pre-galvanised sheet steel, featuring rolled flanges at both ends and flange holes conforming to DIN 24155 specifications. Guide vanes are integrated into the casing to optimise airflow and performance.
The fan uses a mixed-flow impeller with eight spatially curved blades manufactured from galvanized steel. It is dynamically balanced to class G 6.3 in accordance with VDI 20060 and DIN ISO 1940, ensuring smooth and vibration-free operation.
Powered by a totally enclosed 3‑phase squirrel cage motor with Dahlander windings, the unit supports two-speed operation through pole switching. The motor is maintenance-free and fitted with sealed-for-life, low-noise ball bearings, making this fan ideal for variable-speed, high-pressure ventilation needs in industrial and commercial environments.
