Fans of PQ-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 dusty (not abrasive) air and smoke, with max. temperature of 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-high pressures.
