Product details

Aco box SM500 FAN

Variable direction discharge, backward curved centrifugal fan. High efficiency IE2 external rotors motor and IE3 for induction rotor motors. Highest quality Electric motors with thermal protection will guarantee the long life and trouble free operation due to its construction and air cool system. Free running High density HD backward curved Impeller is made of aluminium and dynamically balanced according to G6.3 two plane. Acoustic panels are easily removable which make it easy to install in any direction as well as easy to clean and maintain. Speed controllable 0 to 100% only by High efficiency variable frequency drive, pre-programmed and fully protecting the fan against any sort of harm. Low sound level due to the 25mm thick acoustic panels, to absorb the noise to the highest level. Casing and all corners are made of corrosion resistance aluminium for longer life. Aco-silent fans can be used as extract and supply unit. .
