Aftermarket

Our service capability encompasses all centrifugal 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 has a heritage of over 100 years of fan design and production.
Davidson/Sirocco – the forward bladed 'Sirocco' centrifugal fan was invented in 1898 by Samuel Davidson.
