Waddle fan
Waddle fans, sometimes incorrectly spelled Waddell, were large centrifugal fans, used to ventilate coal mines. They were distinguished by both their extremely large size and by the fan having an integral shroud and so being able to be mounted in the open air. == Waddle Engineering and Fan Company == They were built by the Waddle Engineering and Fan Company Limited, in Llanelli, Carmarthenshire. Their archives are now held by Carmarthenshire Archives〔〔 and the Richard Burton Archives at Swansea University. The fans were most common in their local area of South Wales, but they were also widely used in other mining areas in England.〔 Waddle Engineering were in business from 1830 to 1970. Their distinctive fan always worked at relatively slow speed and so was most suitable for steam engine drive. As high speed fans driven by electric motors became more common, Waddle failed to make this transition.
