111 Windmill Road, Sunbury-on-Thames, Middlesex TW16 7EF,Other, United Kingdom



Airscrew Limited (member of Airtechnology Group) specialises in supplying equipment for rolling stock applications in the railway industry. Products include fans, saloon and cab heating and ventilation, electrical equipment cooling systems and engine cooling systems.

Established for over 30 years, this highly experienced engineering team draws on knowledge that has been gained from the company’s aerospace and defence projects to develop equipment of unrivalled performance and quality.

Products range from off the shelf component fans, to bespoke design components and completely integrated systems. All products combine existing, proven components with bespoke design and new technologies. Airscrew Limited is able to offer shorter development timescales and reduced cost and risk whilst offering optimum performance for minimum mass and space. From a single component to a fully integrated system, Airscrew Limited will deliver the ideal solution.

Specialist fans

Airscrew Limited is the world’s leading manufacturer of specialist fans offering every form of fan configuration including axial, mixed and centrifugal and cross flow.

Tube Axial fans provide high flow and medium pressure ideal for equipment cooling and general ventilation. Where a higher pressure is required, Airscrew has developed Vane Axial fans with a very high aerodynamic efficiency that have been used in place of centrifugal fans.

Centrifugal designs provide high pressure with minimum airflow. Traditionally supplied in a scroll casing, Airscrew has pioneered the concept of Open Running Centrifugal fans with the associated saving of space and weight.

Mixed flow fans offer high flow and high pressure. Applications include engine cooling with hydraulic or mechanical drive. Applications for Airscrew Limited Fans include:

  • Locomotive traction motor cooling
  • Brake resistor cooling
  • Equipment case cooling
  • Dust scavenge
  • Saloon ventilation
  • Engine cooling

Integrated fans

In some applications space and weight constrictions are so severe that conventional ‘stand-alone’ fans are not feasible. Working closely with the customer, Airscrew Limited offers tailored fans that fully integrate with the application eliminating the need for fan casings and brackets. Applications for Airscrew Limited Integrated Fans include

Electrical equipment cooling systems

With the increasing application of electronic equipment the requirement for cooling systems is becoming more common. Airscrew Limited offers its customers a full systems integration capability delivering complete solutions to any cooling application.

Any application referred to the scrutiny and attention of the Airscrew Limited engineering department will be assured of an optimised and innovative solution guaranteed to meet every aspect of the specification. With our engineers involved from initial concept right through the design Airscrew Limited deliver maximum reliability and performance together with the best acquisition, operation and maintenance costs. Applications for Airscrew Limited Equipment Cooling systems include Converter cooling and transformer cooling.

Engine cooling systems

Today’s power pack designers face an ever-increasing demand. In addition to the engine radiators charge coolers, transmission and hydraulic oil coolers compete for space in the engine bay. In response Airscrew Limited offer a complete range of products from fan impellers to complete packaged systems.

Airscrew’s experience allows us to design the most effective cooling group managing the total air side system. Optimisation of both oil and water/glycol systems is achieved using a combination of multiple fans and variable speed fan motors and pumps to accurately match-varying cooling loads without oversizing the system. This together with the option to use heat exchangers matched to Airscrew’s unique range of mixed flow fans permits the design of extremely compact cooling systems. Whether it is a single fan or a fully integrated system Airscrew Limited will deliver the ideal engine cooling solution.

Docklands Light Railway Capacity Upgrade

Since opening in 1987, the Docklands Light Railway (DLR) has been central to the regeneration of east London. Now its significance is far greater than originally envisaged.

West Coast Main Line

The modernisation of the 399-mile (641.6km) rail route between London and Glasgow and its key divergences to Birmingham, Liverpool and Manchester, was the largest rail project to date in the UK.

Channel Tunnel Rail Link (CTRL)

Full UK Government approval was granted in 1996 for the two sections of the 69-mile (108km) high-speed Channel Tunnel Ra

Gatwick Express

Gatwick Express, the first dedicated city centre to airport rail link in the UK, has undergone a major service transformation with the introduction of a fleet of brand new trains at the end of 2000. However, February 2006 saw the UK Government announce its likely demise because it is using up valuable line capacity.

London Underground Jubilee Line

Construction of the extension of London Underground's Jubilee Line from Green Park, through south London and Docklands to Stratford, proved a troublesome project.

Arlanda Express High Speed Rail Link operated by A-Train AB, Sweden

24 November 1999 saw the inauguration of the new, dedicated high-speed rail link between Stockholm Central railway station and the city's main airport, at Arlanda. The airport is at a competitive disadvantage over other major city air terminals, as it is 42km (26 miles) from the city centre.

Oslo Airport (Gardermoen) Rail Link

Through a combination of overcrowding, a lack of expansion options and no rail links, all in the context of forecasted long-term rising demand, the Norwegian government decided to replace Oslo Fornebu as the capital's principal airport.

Kuala Lumpur

Light Rail came to Kuala Lumpur in 1998 with the creation of the first section of an automatic mass transit system, runn
