UK’s No. 1 Commercial Fan

The Lo-Carbon T-Series Fan range utilises a low energy DC motor, developed to improve performance, lower running costs and maintain T-Series’ rugged reliability.

Roof Fitting Kit

Designing ventilation systems with the unit mounted in a skylight or a flat roof is easy. With a low profile cowl, the Lo-Carbon T-Series Roof model is suitable for installation in horizontal, angled (max pitch 30deg) and vertical glass and for fixing plates in roofs. For vertical windows or walls in exposed areas and single and double glazing including most types of glass up to 32mm thick. Greater thicknesses can be accommodated using extended fixing rod sets. Both sizes of Vent-Axia roof plate assemblies can be fitted easily into flat roofs.

Instantaneous Shutter

With energy saving in mind, Lo-Carbon T-Series models are supplied complete with an integral, instantaneous, automatic louvre shutter concealed behind the interior grille. It will operate on both intake and extract and at any angle of mounting. The shutter is electronically controlled by an actuator with a damped action giving quiet operation during instant opening and closing. When the fan is used with a Lo-Carbon T-Series controller, the shutter can be set open with the fan motor switched off to provide natural ventilation without the security risk of an open window.

Top Socket

A connector Top Socket is standard on all T-Series fans. Allowing fast and trouble-free mains connection.


Motor purpose-designed. Suitable for running at any angle. Quiet running, enclosed. Suitable for operation in ambient temperatures from -40°C to +50°C. Fitted with self resetting Standard Thermal Overload Protection (S.T.O.P.). Supply voltage 220-240V/1/50Hz

Flat roof

LoWatt T-Series roof models may be installed through solid roofs using a roof plate assembly and, if required, an eggcrate grille or louvred grille in the ceiling below. Alternatively, if ventilation is from a suspended ceiling, single spigots and flexible ducting may be used to connect the unit and extract grille.

Corrugated roof

LoWatt T-Series roof models are suitable for fixing through corrugated sloped and vertical cladding using a suitable soaker flange. A suitable sealing compound should be used between the plate and the exterior unit seal.

Pitched roof

LoWatt T-Series roof models may be installed in fixing plates with zinc or lead weathering apron (provided by others), fitted directly to a tiled or slated roof to provide a water-tight installation. A suitable sealing compound should be used between the weathering apron and the exterior.
