Following on from a number of posts and comments I asked Charnwood whether a finer filter could be fitted, from their own range, to this extractor.
This is the reply I received from Charnwood which may be helpful to some of you.
There are no upgrades available for the W690.
The standard bag on the W691 is a cloth bag around 10 microns. You can upgrade to a 2 micron needle felt bag £44.00 You can also upgrade to a 0.5 micron cartridge filter £159.00
Our 2 micron filter is suitable for somebody mainly using timber and occasionaly MDF. If you are using either MDF continously or collecting from a sander then the cartridge filter is the ultimate step. Only professional users generaly buy the cartridge filter to use with one of our Trade rated machines, however it will also fit the DIY models.
