Prices & Options
The Helios VARW 225/4 Ex is a high-performance in-line mixed-flow fan designed for high-pressure applications in potentially explosive environments. The cylindrical casing is made from pre-galvanised sheet steel and features rolled flanges on both ends, with mounting dimensions and hole patterns conforming to DIN 24155 standards. Internal guide vanes are incorporated to optimise airflow efficiency.
The fan utilises a mixed-flow impeller with eight spatially curved blades constructed from impact-resistant polymer. The impeller is dynamically balanced to class G 6.3 as defined by VDI 2060 and DIN ISO 1940, ensuring stable and vibration-free operation.
A totally enclosed single-phase condenser motor powers the fan. It is maintenance-free and includes low-noise, sealed-for-life ball bearings. The entire unit is built to explosion-proof standards in accordance with ATEX regulations, making it suitable for use in environments with flammable gases or dust.
