ACI's Slimline range of fans is available with either single or double inlet curved centrifugal blades. They are an ultra compact design based upon an ‘inside out' design that permits dimensions to be kept to an absolute minimum.
The QB EC Range of centrifugal fans are equipped with EC-technology that uses integral electronic control to ensure that the motor always runs at optimal load. EC fans are favoured for their economical use of energy and simplified control. The fans are driven by energy-saving motors with electronic control for optimal operating efficiency.
