Smoke Fans

Our SmokeVent has been
specifically developed for
emergency smoke extract

We are a major supplier of axial flow fans for smoke ventilation. Our standard range can operate as part of the main extract system, or as fans for emergency clearance in hazardous fire, smoke and fume conditions.

Unique Design

Our high efficiency adjustable pitch aerofoil impellers have been developed in line with the latest ErP legislation to deliver outstanding efficiency capabilities for overall lower running costs.

Quality Assured

Every smoke fan we manufacture is tested individually in our on-site test bay to ensure its electrical loading and vibrations are in normal operating limits before undergoing visual inspection and tip-clearance checks in our dedicated Quality Assurance Department.

Cost Effective

Our highly efficient impellers provide an economic way of moving high volumes of air at low to medium pressures in standard operation. Improved impeller geometry including increased blade chord and twist provides 7% higher efficiency reducing overall energy consumption.

Safety and Control

A mechanical smoke extract system that is independent from external conditions allows emergency control of the situation by the fire services. The removal of smoke assists the safety of the occupants in the event of a fire.



All casing parts are heavy gauge mild steel sheet, roll formed and welded, then hot dip galvanised to BS EN ISO 1461 after fabrication to provide a long lasting and robust construction. Flanges are roll formed as part of the casing. Motors and axial impeller are mounted within the length of the unit casing.


Motors are totally enclosed metric type to IP55, with sealed for life bearings below 160 frame. Standard industrial paint finish and class H insulation to EN 60034-5, suitable for use at normal continuous duty and a once only use under smoke operation at 200°C, 300°C and 400°C for 2 hours. Flying leads are brought out via a temperature resistant conduit system, to an external IP55 terminal box for customer cabling interface.


Adjustable pitch aerofoil impellers are provided with blades made from high quality aluminium (LM6) natural finish. Impellers are factory set at an angle to exact customer requirement. The hubs are manufactured from die cast aluminium alloy (LM6 or LM24). Assembled impellers are dynamically balanced to ISO 14694.

Quality Management

Units are certified to EN12101-3 and LPCB third party certified. Units are designed and manufactured with procedures as defined in BS EN ISO 9001. Units are tested to ISO 5801:2007 (airside performance) and BS 848 Part 2:1985 (sound performance).
