Decades of experience form the basis for the manufacture of high-quality and efficient centrifugal fans by SIEGLE + EPPLE. To ensure energy-optimised plant operation, our fan designs and control strategies are tailored and adapted to each individual application. In addition to our standard range of fans in a wide variety of performance classes, available in both double-flow and single-flow designs, we design and manufacture bespoke special-purpose fans. Depending on the application, these are available to meet increased requirements for running quality up to G 1.0 in accordance with DIN ISO 1940, for high temperatures up to 400 °C, for high chemical exposure in special materials, or in explosion-proof versions in accordance with ATEX guidelines.
