138 AC OUSTIC C ABINET FAN S CAB Series, Forward Curved Centrifugal Fans A F E B C ØD De s cript io n Applicat io ns The CAB range of acoustically lined cabinet fans are specifically designed to provide extract ventilation solutions for noise sensitive environments. The range comprise s o f six nominal sizes. All models incorporate single phase, 230V 50Hz, direct-drive low pressure centrifugal fans available in two (2) or four (4) pole speeds. All models are supplied with a remote moun- ting wiring outlet box to facilitate installation and connec t ion to external contr ols. Air volume pe rf ormance ranges fr om 200 up to 3,950 m 3 /hr. T he CAB range are suitable for many general ventilation applications where the noise level of the ventilation system is of particular importance . Typical applications would include venti lation s ystems for : – Commercial off ices. – Restaur ant s and cafes. – Libraries and pub lic buil dings etc. Construction Dimensions (mm) Casing The fan ca sings are manufactured fr om he avy gauge galvanised sheet steel and internally lined with a dense Melanex (M1 Type) acoustic insulation. All models incorporate inlet and discharge circular duct connection fl anges wit h integrated rubber air seal. The specific design of the produc t s enables a cover to be removed and the motor / impeller assembly accessed without the requirement of removing the fan casing from the ducting. T his CAB fan cover is s upplied as standard wit h “ quick-fix” fixings to enable fast r emoval or fit ti ng w ithout tools. All mod els are also supplied with four mounting feet to facilitate any ceiling, wall or floor mounting installation. Motor / Impeller Al l models incorpor at e a s ingl e p hase, 230V 50Hz, direct-drive low pressure forward cur- ved centrifugal fan (with scroll). All motors included in the CAB range are of, “enclosed,” type and are fully speed controlable using voltage regulation. To obtain the Sound Power Level Spectrum, subtract the corresponding correction factor shown below from the value given in the Technical Charac teristics table ( value s in Hz).
