Running your extractor all day, every day? With the same motor input as the FM-300, this unit will flow 30% more air – meaning you can run two machines generating a large volume of waste with ease.
This is done by a computer-model enhanced impeller design along with a more efficient motor mating to increase the capacity. Perfect for school, industrial or a demanding home user. Comes on castors to be moved around easily.

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.
Please note that due to the shipping weight of this machine that a tailgate drop fee of $80.00 may need to be charged. Please see our Freight & Returns for more information.
