Uses and Features
The AH series centrifugal fans are backward-curved blade fans with ten blades. The fans are manufactured in a fully welded industrial structure, EXTRA HEAVY DUTY. The fan has high efficiency and is mainly used in situations requiring medium to high pressure and where the air stream contains low to medium concentrations of dust and particles, such as: suction from extraction and filtration systems, suction from air supply systems with especially long duct runs, suction from machines, and so on.
Thanks to the high efficiency of the fan and its construction, significant cost savings in operational and maintenance expenses are possible.
