Duct fan VC

centrifugalwith external rotor

VC – Duct fan units Small dimensions. Maximum simplification of ductwork due to linear air discharge. Installed inside ducts. Closed synchronous motor with external rotor – single-phase 230 V / 50 Hz – Class E thermal insulation. IP44 protection – Terminal box IP 55. Built-in temperature probe / Sealed bearing, lubricated for whole service life / Permanent condenser. Can operate on horizontal or vertical axis. Galvanised steel plate body. Centrifugal impeller with backward-curve fan blades, fixed to rotor with dynamic balancing. Possibility of speed control via variation of power voltage (min. voltage for restart: 60 V). Operating temperature limit: 40 °C.
