Extraction unit is quieter, more efficient and cheaper

The extractor fan for HSF machines has now been redesigned for improved suction and less clogging of the filter bag. The new design and the incorporation of sound deadening panels has also significantly reduced noise levels, and a direct comparison with the previous model reveals a drop in noise of as much as 10dB!  A final improvement is the simple modular construction that means the fan can be packed into a smaller, lighter case reducing the cost of transport.
