Serie CTC - NFR - NFL

The fans of the CTC - NFR - NFL series are medium-pressure centrifugal fans with backward-curved blades (CTC) or backward flat blades (NFR-NFL), available in both single and double inlet versions, specifically designed to convey clean or slightly dusty air with flow rates up to 1,000,000 m³/h and pressure up to 8,000 Pa. These fans find their main application in pneumatic transport, air barriers, liquid agitators, and glass cooling or tempering. What distinguishes the CTC series is the ability to mount two different types of impellers, standard or self-cleaning, depending on the amount of dust present in the fluid, within a single housing, thus achieving the highest levels of standardization and functionality. One of the main features of these series is the robust welded construction made with thick sheets, suitably reinforced to ensure minimal noise and the absence of vibrations and pulsations.

The CTC - NFR - NFL series fans are built in 16 sizes with impellers ranging from 315 mm to 2250 mm in diameter. From size 1600 onwards, the fans are supplied with the casing divided into two or more parts for transport. The impellers are statically and dynamically balanced with electronic equipment in accordance with ISO N.1940 standards grade G=2.5.
