CATALOGUE

The fans of the PR-L series fi nd their main application in commercial and industrial plants of air-conditioning, ventilation, heating and filtering; they can be used as well in industrial processing (baker ovens, spray booths, boilers, silos, cooling systems, etc.). PRL fans can convey clean or slightly dusty air and smoke with max. temperature from minimum temperature of -20°C to a max. temperature of 80°C in 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 very high capacities and low pressure.

Upon request:

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