The fans of the PS-L series find their main application in industrial plants of conditioning, ventilation, heating and filtering; they can also be used as part of manufacturing process (wood industry, chemical industry, mills, mines, foundries, etc.). They can convey very dusty (not abrasive) airand smoke, with temperature from -20°C to 80°C in the standard configuration and up to 300°C with specials constructions.

The series foresees direct drive version (execution 4) and belt drive version (execution 1, 9 and 12). Suitable for high capacity, medium pressures.

Upon request:

  • High temperature version suitable for conveying hot gases, Max 150°C (PS-L/AT EX4)
  • High temperature version suitable for conveying hot gases, Max 300°C (PS-L/AT EX1,12)
  • Corrosion resistant version, manufactured with casing, inlet side and impeller in stainless steel AISI304 (PS-L/INOX)
  • PSL-ATEX according to Directives 94/9/CE and 2014/34/UE
