ERV

Centrifugal fans for industrial drying systems and other applications

Bellmouth calibrated as a measuring element for volume flow rate measurements. The characteristic curves have a steep, stable progression with a wide design range and high efficiency progression. On average, the total acoustic power level of the centrifugal plug-in fans is 5 dB lower than the value of the dual-inlet casing fans with comparable flow cross-sections

  • 19 sizes
  • Impeller’s nominal Ø 200 to 1,600 mm
  • Volume flow rate V max. 140,000 m3/h
  • Stat. differential pressure ps max. 3,150 Pa
  • Peak efficiency of 76%
  • Due to a high delivery coefficient, the fan can be used in a highly efficient manner across a large volume flow rate bandwidth
  • Impeller also suitable for installation in dryers up to a conveying temperature of +250°C
  • In connection with installation frame (motor outside of flow)
