X RANGE
HIGH VOLUME LOW SPEED HVLS FANS
THE GENTLE GIANT OF AIR MOVEMENT
The HVLS High Volume, Low Speed fans are designed to eliminate the build-up of hot stagnant air by maintaining constant air movement.
ENGINEERED TOUGH
Industrial grade components of the highest quality. Anodised extruded blades provide strength while keeping the unit lightweight for increased efficiency.
SILENT OPERATION
The Silverback HVLS uses a gearless drive system, which makes for incredibly quiet running.
ULTRA ENERGY EFFICIENT
Made and tested in our European labs, our Silverback X HVLS Fans are powered with the latest EC brushless motor technology. This enables the unit to equally destratify and distribute air in the most efficient and cost effective manner.
SEVEN MODELS AVAILABLE
With models available in 3, 4, 5, 6 and 7m diameters Silverback X HVLS is adaptable enough for all applications from sports centres to manufacturing facilities.
TWO TIP COLOURS
Coordinate your HVLS fan to suit your space. The hub covers and impeller wingtips are available in your choice of green or black.
SAFELY DESTRATIFY AND COOL
Ventilation built to withstand the toughest environments.

DESTRATIFICATION
& COMFORT
The Silverback X range can save energy costs and increase productivity while respecting the environment!
The X range of high velocity, low speed (HVLS) fans generate a gentle, slow moving airstream that covers a large area even when they are installed in a very high ceiling. They help create a more comfortable indoor space for building occupants while lowering a building’s running costs and reducing its carbon footprint.
The Silverback X range can be controlled with the easy to use Aviator controller or a Building Management System.
SUMMER COMFORT
In summer, an efficient and continuous air circulation provided by a HVLS fan, creates a natural evaporative cooling effect for occupants. It also eliminates hot and cool spots in the building by improving the internal environment, making the air-conditioning system work less and preventing large internal atmospheric losses each time doors and windows are opened.

TOUCH SCREEN MULTI-FUNCTION CONTROLLER
The Aviator touchscreen controller is designed to manage a mini-network of Silverback X high volume, low speed EC fans. This multi-fan control system features a wall mounted 9cm LCD touchscreen display that communicates to each fan individually from a central location. It can alter the fan speed in real time by simply changing up or down the percentage value on the display. Each fan can be individually turned on or off by touching the relevant power button icon.
FAN SELECTION CONTROL
The Aviator can control up to 4 Silverback X HVLS fans from one convenient digital controller.
HVLS COMMUNICATION
The communication between the Silverback X HVLS fans is established by ‘daisy chaining’ the fans together via a discreet RS485 cable.
RUN-ON TIMER
Featuring an adjustable run-on timer for applications that require the fans to continue running for a pre-set period. Particularly suitable for sports centres and working environments where the HVLS fans are required to operate to a set time.
EASY TO USE
The Aviator controller is incredibly user friendly. The easy to read, touchscreen display allows you to operate individual fans with just a tap of your finger.
INSTALLATION
The distance between the lowest part of the Silverback X HVLS fan and the floor must be 2.7m. If necessary, a different length downrod (400m or 1500m) can be supplied on request.
The installation of the Silverback X HVLS fans is quick and simple so you can easily fit out your entire facility. To maintain the efficiency of the fan and comfort of your workers, the fan should not be placed near a supply air outlet or exhausting inlet of other HVAC equipment.
