Acoustic Cabinet Fans - CVB Series

CVB Series

Features

The Centribox CVB range of acoustic cased fans are specifically designed to provide ventilation solutions for noise sensitive environments and incorporate direct-drive low pressure centrifugal fans. Typical installations would include commercial offices, restaurants and cafes, libraries and public buildings etc.

Construction
The fan casings are manufactured from heavy gauge galvanised sheet steel and internally lined with with a dense “nonflammable” Melinex (M1 Type) acoustic insulation. All models are supplied, as standard, with circular duct connection flanges on the discharge and inlet panels. A variety of different connectors are available.
The product is designed to enable the casing side panels to be removed for access to the motor/impeller assembly without removing the the fan case from the ducting.
All models are supplied with four mounting feet and an industrial grade cable entry gland (located on discharge panel side) to facilitate installation and wiring.
All models incorporate double inlet direct-drive low pressure centrifugal fans (with scroll) with galvanised steel forward curved impellers. All fan assemblies are fitted to the casing discharge panel using a rigid support frame with two anti-vibration mountings.

Motors
All motors are factory matched and directly mounted to the scrolled fan casing using a rigid support frame. The complete motor, impeller and fan scroll assembly is then dynamically balanced to ISO 1940 standards.
The CVB range is available in Single Phase, 230V 50Hz, with four and six pole speed motors, supplied with capacitor and Thermal Overload Protection (internal automatic operation for all single phase models).
