Helios AMW 315/4

Medium-pressure duct fan with a cylindrical duct casing and flanges on both sides, directly driven. The cylindrical duct is made of galvanized steel sheet and features a formed flange on both sides as well as a hole pattern according to DIN 24155 Sheet 3, with an integrated guide vane. The axial impeller is made of plastic and has 14 spatially curved blades. It operates vibration-free thanks to dynamic balancing according to quality level G 6.3 VDI 2060 and DIN ISO 1940. The fan is equipped with a single-phase AC capacitor motor that has a closed design and maintenance-free operation, with thermal contacts integrated into the winding. The speed can be adjusted by voltage reduction, and it features sealed, low-noise ball bearings with long-term lubrication, making it non-reversible.
