Howden has been at the forefront of axial fan technology since the beginning of its development

We continue to lead the world in raising energy efficiency, improving reliability and reducing lifetime costs for our customers. We design and manufacture bespoke fans for power and mining to standardized fans supporting ventilation in transport tunnels and air provision in light industrial settings.

Benefits of Howden Axial Fans

  • Wide product range gives us the ability to match every duty condition with the optimal performance level using either single or two-stage configurations
  • High efficiency designs to minimise operational costs
  • Specialist application knowledge supporting material selection and engineering design for reliable long-term continuous use
  • Alternative fan technologies ensuring the best available technology is offered
 

Axial Fans Animation

Howden’s axial fan technology serves a wide variety of applications and industries. See a short animation showing the main components and airflow through our Variax fan.

Alphair Jetstream

The Alphair fans are heavy-duty axial fans designed specifically for main mine ventilation. These robust adjustable-pitch fans can be installed vertically or horizontally to supply critical air or remove stale air and gases. A comprehensive flow of up to 1 million CFM (1.7m m3/h) can be achieved while meeting the high standards in efficient operation and low maintenance through reliable service.

Jetstream AX

Howden’s Jetstream AX fans are specifically designed to give the highest fan output at low power consumption, providing high efficiencies of up to 85% across a broad operating range. They are ideally suited to provide auxiliary or secondary ventilation within underground mines fans although can also be deployed for main air supply.

Their modular design gives commonality of parts and flexibility on the arrangement, components, number of stages, thereby allowing customization if needed.

Variax/PF

Variable pitch axial fans combining the highest efficiency levels available today with an exceptionally flexible, customer focused design. The Variax and PF fans are proven across a wide range of applications within mining, power, metals and wind tunnels.

The fans are fully custom-made design to order specification and offer a wide range of configurations and performance envelopes to match each application.

VA series

The VA series of industrial axial fans are designed for continuous operation and are highly dependable. They are used within applications such as ventilation, aeration and drying, extraction, cooling and air conditioning. The range is highly flexible to specific customer requirements with Howden engineers able to provide design adjustments and offer different configurations. ATEX-classification is available on request.

VA series

UMAF

The UMAF range is ideal for applications requiring air or extraction of air/gases in flows of up to 400 m3/s. These fans are extensively used with tunnel ventilation/smoke extraction, Industrial process for combustion air, and in higher-pressure Direct Air (carbon) Capture systems

Fans can operate uni-directional or fully reversible. Flow control is enabled by blade adjustment either at standstill or during operation depending on model selected and also achieved using a Variable Speed Drive (VSD)

In the case of tunnel ventilation, they are tested to operate at 200ºC/1h or up to 400ºC/2h.

UMAF

AP/Q Jet Fans

Jet fans are typically used in tunnel ventilation systems using the longitudinal technique with single or bi-directional traffic. The AP/Q range can operate with flows of up to 50 m3/s with thrust of up to 3360N

Fans can operate uni-directional or fully reversible (uni-directional may also operate in reverse with a lower thrust). Flow control is achieved using a Variable Speed Drive (VSD).

Wide range of standard sizes, all incorporating rotors that are dynamically balanced to eliminate vibration and noise. Fans can be fitted with silencers for outstandingly quiet operation and are tested to operate at 200ºC/1h or up to 400ºC/2h

Aftermarket

Our service capability encompasses all axial fans from own brands to those of other manufacturers.

For own fan brands we offer a complete range of aftermarket solutions from OEM spare parts, analysis and troubleshooting and general maintenance, to fully engineered upgrades and retrofits for operational performance and life extension.

Our brands include those currently available as new equipment such as Howden and Alphair, but also those acquired over the course of our 160 years of history such as:

  • Buffalo Forge – originating in 1878 and acquired by Howden in 1993. Buffalo Forge fans are used across a wide range of industrial and commercial applications. Buffalo Forge fans were central to the development of modern HVAC systems, and continue to heat and cool some of the most iconic buildings in North America and around the world. Howden retains a base in Buffalo, NY as part of our North American business.
  • Turbowerke Meisen – now operating as part of Howden Germany. Turbowerke was acquired in 1991, but has a heritage of over 100 years of fan design and production.
  • Nordisk - supplied the world’s first variable pitch axial flow fan in the power generation industry in 1951. Part of Howden since 1993, today their fan technology remains part of our axial fan range.
