On request, we produce pressure-tight and pressure surge-tight fans for up to 12 bar system pressure. We will be happy to quote you reference projects. Abstand Advantages: • Widely diverse performance limits • Wide range of operating temperatures from -100 to +300° C • Explosion-proof according to ATEX (zone 1, 2, 21 and 22 according to Directive 94/9 EC) • Housing calculation according to Pressure Vessel Directive (AD 2.000) Abstand Abstand VH2Sa/RU 355 M VH2Sa/RU 315 KG U-HNN/RE 630 R-s Abstand Abstand Multi-stage special fabrication Abstand Certain processes and applications in the pressure range above 30.000 Pa have marginal conditions which make it impossible to use classic compressors. This is where our multi-stage blowers come into play. The welded impellers mean that a wide variety of materials are available for innumerable applications. Abstand Advantages: • Impellers are installed in a shared housing • Our special designs are characterised by their considerable convenience in terms of servicing and maintenance, because the bearings are on the outside. Irrespective of whether the impeller is on a cantilevered mounting or is installed between the bearings. • Gas-tight fans for low-temperature and high-temperature applications. • The components that come into contact with the media can be configured without oil or grease • Possible pressure increase up to 50.000 Pa Abstand Abstand Special construction for hot gas Abstand Our decades of experience in hot gas ventilators enable us to offer pioneering products today in temperature ranges up to 900° C with nominal sizes up to 1.600. Innovative impeller geometries contribute not only to meeting the aerodynamic requirements of industrial furnaces but also the extreme demands in terms of strength, thereby guaranteeing the highest performance. Abstand Advantages: • Widely diverse performance limits • Different cooling systems are possible • Wide operating temperature range up to +900° C Abstand Available impeller types: • backward-curved blades • forward-curved blades • Drum impeller • Axial impeller Abstand All hot-gas fans are available with or without a spiral.
