Auspex Posted October 10, 2012 Share Posted October 10, 2012 The HEPA standard is to remove 99.97% of all particles greater than 0.3 micrometer. Multi-stage is the way to go; a large area will be needed to handle the volume of air that a dryer blower moves.

rejd Posted October 11, 2012 Share Posted October 11, 2012 Thanks for the info Auspex, that is what I will shoot for then. And yes, that blower moves some serious air.

Terry Dactyll Posted October 11, 2012 Share Posted October 11, 2012 Collecting the dust is the problem... Very often dustbags let the fine particles straight back out....I'd be tempted to pipe it outside if you can....Even flexible trunking may do it... Cheers Steve... And Welcome if your a New Member...
