bradleyheathhays Posted September 24, 2023 Report Share Posted September 24, 2023 2 questions Is there an alternative to the Whiteside UDC9112 Ultimate Trim Combination Bit? found here and What's this brand/model of full face respirators I see in some woodworking videos please? Might find them on turners. I've seen models with what I think are two fan vent holes on the top and I think it works by forcing filtered air into the mask. I'd imagine they're not cheap.

gee-dub Posted September 24, 2023 Report Share Posted September 24, 2023 Just search for "compression bit for router" or the like. The bit is called a compression bit. The right search term sometimes eludes me too ;-) Positive pressure PPE sounds like what you are after. Again, several makers. Pick your quality level / price point. Trend Air Shield and Axminster Evolution seem popular. Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted September 25, 2023 Report Share Posted September 25, 2023 Full face, forced air respirators are popular with welders. Maybe shop through welding supply houses. Quote Link to comment Share on other sites More sharing options...
