I have an old 3M Airmate 3 system (yellow hardhat). It's getting harder to find parts, in particular replacement visors and beard seals for the helmet. I have several blower units and filters are available so I would like to replace the helmet only. I figure I can adapt my hose to a new headpiece. Any recommendations for a helmet substitute, or a source for parts? I know I will have to bite the bullet and get a new system eventually but would like to put it off.
