A new speed-controllable fan, designed for applications where space is at a premium, is being added to the SlimLine range of fans from Air Control Industries.
Developed originally for use in vending machines, but since proven for control cabinets and similar applications, the new VBL9/9 fan produces a maximum flow rate of 560 cfm and a static pressure of 3.1 in SWG. It is available in 230V and 115V versions so can be designed-in for equipment that is intended either for home or export markets. In addition, it has a demountable inlet plate that facilitates integration of the fan into customer-made inlet arrangements.
Like other products in the ACI SlimLine range, the VBL9/9 features a precision, gravity-die-cast impeller scroll that results in a slim profile, which allows flush mounting of the fan on the inlet or outlet by means of tapped holes. The scroll impeller is also light in weight and quieter than conventional sheet metal fabrications.
Common features across the SlimLine range include an external rotor motor built into the fan, plus fully integrated bearings. In addition, the design of the assembly helps to shorten the fan, permits precision balancing and achieves efficient cooling by virtue of the fact that the fan is located directly in the centre of the air stream generated - which also enhances the unit's longevity.
As well as simple voltage-regulation speed control, the SlimLine range can also be supplied with an optional DC control board for connection to either PLC or PWM controllers.
