Acoustic Kitchen Extract Fan

Range of in-line cabinet fans, manufactured from galvanised steel sheet with double thickness side panels internally lined with 17 mm thickness of fireproof fibreglass acoustic insulation (M0).

All models incorporate backward curved centrifugal impellers, dynamically balanced and are supplied with circular duct connection flanges and remote terminal box.

~ All the motors are IP55, Class F(1) insulation, with thermal protection (2).
Electrical supply:
~ Single phase 230V-50Hz. 
~ Air stream temperature limits -40ºC to +70ºC.

The extremely low noise level makes these super-silenced boxed fans an exclusive and unequalled series.
SS-BOX fans are suitable for being installed in small exhausting plants, where limited dimensions and easy installation are also required. Other peculiar features are: the possibility of easy removal of motor-impeller assembly for maintenance, the standardized round inlet and outlet flanges and the possibility of speed regulation. They are suitable to convey clean air up to a max temperature of 40°C. They must be installed only in horizontal position.
Note: The connections to the motor are inside the unit and the wires normally exit the fan via the ducting. (Using a grommet).

Centribox CVB 270/270-1/2

Large Acoustic Cabinet fans manufactured from heavy gauge galvanised steel sheet and internally lined with melamine foam flame retardant acoustic insulation (M1).

The specific design of the product enables the casing side panels to be removed and the motor / impeller assembly accessed without having to remove 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.
All models incorporate double inlet single phase direct-drive forward curved centrifugal fan fitted with anti vibration mounts and IP55 remote terminal box. 

Manufactured by S&P and continuing their range of quiet fans, the CAB range of acoustically lined cabinet fans are specifically designed to provide extract ventilation solutions for noise sensitive environments. The range comprises of 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 mounting wiring outlet box to facilitate installation and connection to external controls.
These are slightly more expensive than the Rucks, but have better acoustic properties and build. Recommended..
Air volume performance ranges from 200 up to 3,950 m3/hr.

The UPA range are suitable for many general ventilation applications where the noise level of the ventilation system is of particular importance. Typical applications would include ventilation systems for:
- Commercial offices.
- Restaurants and cafes.
- Libraries and public buildings etc.

The fan casings are manufactured from heavy gauge galvanised sheet steel and internally lined with a dense Melanex (M1 Type) acoustic insulation. All models incorporate inlet and discharge circular duct connection flanges with integrated rubber air seal. The specific design of the products enables a cover to be removed and the motor / impeller assembly accessed without the requirement of removing the fan casing from the ducting. This UPA fan cover is supplied as standard with “quick-fix” fixings to enable fast removal or fitting without tools. All models are also supplied with four mounting feet to facilitate any ceiling, wall or floor mounting installation.
Motor / Impeller
All models incorporate a single phase, 230V 50Hz, direct-drive low pressure forward curved centrifugal fan (with scroll). All motors included in the UPA range are of, “enclosed,” type and are fully speed controlable using voltage regulation.

After much work given on the noise figures for these fans, it seems that they compare favorably with the Ruck fan, being quieter by a few decibels. They are also built a little more sturdily.

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.

Toilet extract ventilation in offices, hospitals, school, retail outlets plus other areas where run and standby operation is required.
