The CAB TWIN range comprises 13 sizes of centrifugal twin fans with acoustically-lined cabinets; each consisting of two direct-driven low pressure centrifugal fans which work independently for run and standby plus duty-share function. The low-noise forward-curved fans are fitted with maintenance-free single phase motors. Recirculation of air is prevented by integral back-draught gravity shutters.

Impellers are designed for high efficiency and are manufactured from galvanised steel and balanced to ISO-1940. The fan housings are of heavy gauge galvanised steel sheet.

The cabinets are welded and are lined with 25mm of flame-retardant V0 rated acoustic insulation lining (50mm insulation is available to order). As standard, they are supplied suitable for mounting indoors; however weatherproof units for roof mounting are available on request. The cabinets are provided with 4 corner fixing holes for ease of mounting horizontally, with access either from above or below the unit via the panel secured with screws.

Motors are suitable for continuous operation at up to +40ºC ambient temperature.

The units are fitted with an IP54 rated terminal box positioned on the inlet face of the cabinet.
Wiring to the fans is made to dedicated 3-way terminal blocks (one for each fan). The terminal box is suitable for standard cable gland entries.
