A great value-for-money extractor for home workshop use. It has a larger motor for extra capacity and with a computer-balanced impeller measuring 300mm, it is generally suitable for extraction of two machines at any one time.
It is generally recommended for large-volume extraction (like planing or heavy-duty routing) to block off one of the inlets for maximum suction through one path.
||2 x 4in or 1 x 5in

PLEASE NOTE - the extractor is shown fitted with the optional Pleated Filter Cartridge (PFC). It normally comes with a needle felt bag as shown in the last image of the gallery.
It Starts With Air Flow
There are two measurements of extractor efficiency – air flow which we measure in in cubic feet/minute (CFM) and the other lesser known measurement is static pressure that we measure in inches of water (in/H2O).
Most woodworkers buy on CFM, but this is only a measurement of the extractor flow when no hose is attached and at the head of the extractor – not a common real-world measure. On the other hand, static pressure measures the resistance once hose has been attached.
This will of course vary depending on the hose size so we list all static pressure measurements with the most common size 4in hose for consistency of comparison. As hose size increases static pressure will decrease and vice versa for smaller hose.
So make sure when you compare extractors that you get the static pressure rating as well as the CFM to ensure that you are getting a machine that will work as well as the Sherwood range.
