Prices & Options
The Helios VARW 450/4 is a high-pressure in-line pipe fan designed for efficient air handling in ducted ventilation systems. Its cylindrical housing is made from galvanized sheet steel, featuring flanges on both ends that comply with DIN 24155 hole pattern specifications. An integrated guide wheel enhances airflow direction and overall system performance.
This model uses a semi-axial impeller with eight spatially curved blades crafted from durable thermoplastic. The impeller is dynamically balanced to class G 6.3 according to VDI 2060 and DIN ISO 1940 standards, ensuring smooth, vibration-free operation.
The fan is powered by a single-phase AC capacitor motor in a closed, maintenance-free design. It includes thermal contacts embedded in the winding for protection, and features sealed, low-noise ball bearings with long-term lubrication. The motor supports speed control via voltage reduction and is not reversible, making it well-suited for fixed-direction, high-demand ventilation systems.
