The high volume of air moved means this unit is capable of extracting from up to three machines simultaneously or through a longer hose system than smaller machines. Hose systems can include branches off to different dust producing machines around the workshop. The maximum recommended hose length between extractor and collection point is 10 metres. There is no limit to the total length of hose used in the network but any unused branches must be capped off or closed using a gate when not in use.

The standard cloth filtration bag is replaced with a cartridge filter to increase the filtration performance down to a super fine, 1 micron particle size. The extra deep pleats in the filter material, increase the surface area of the filter so that there is no loss in air flow compared to the original cloth filter.

This allows the extractor to be used for operations which produce very fine dust such as sanding and cutting MDF. The particle size of fine woodworking dust is generally between 2 and 3 microns. Research shows 99% of wood dust, produced by machining softwood, hardwood or MDF, is within that range. The extractor can still be used with all the normal workshop machines which produce dust and chips, such as: bandsaws, table saws, planers, thicknessers and spindle moulders.

To ensure a long life without any deterioration in performance the filter includes an internal cleaning device. Gently rotating the handles after each use, moves the internal paddles which clean the inside of the filter and prevent clogging.

Supplied with a steel fan, 3 way inlet, six castors, NVR switch, quick release metal straps on all bags, 1.6m power cable (No plug).

A 415v, 3 phase electric supply is required for this machine. We recommend fitting a 16amp plug.

Hose is not supplied as standard, our 100mm diameter transparent hose is recommended, sold by the metre.
