MSA has made the determination to discontinue Pressure-Demand versions of the Ultravue Facepiece, effective immediately. This does not impact Demand versions of the Ultravue or Ultra Twin facepieces. These facepieces will continue to be available for approved Air Purifying Respirator (APR) and Constant Flow Supplied Air Respirator platforms. This decision was made based on the low volume of replacement masks required and the level of support needed to maintain supply chains for components of the pressure-demand products.

A full list of impacted part numbers can be found in the attached notice.
