• Volute casing in die cast aluminium, protected against atmospheric agent by epoxy paint. Support feet are integral part of the casing.
• Single inlet, open blade, radial impeller in die cast aluminium.
• Execution 5 (with impeller directly coupled to flanged motor).
• Fixed orientation RD 270°.
• Asynchronous three-phase or single-phase motors according to international standards IEC 600034, IEC 60072, EMC 2004/108/CE, LVD 2006/95/CE, CE marked, IP 55, class F, suitable to S1 service (continuous working at constant load).

The centrifugal fans of the F series are designed to convey clean and not-abrasive dusty air and smoke (even with limited presence of chippings and fibers), up to a maximum temperature of 80°C. They are suitable for all the industrial applications where small air volumes and high pressures are required. The series consists of 4 models. The motor is directly fitted to the radial impeller. The noise level is very low due to thickness of the die cast impeller and volute casing.
