Like most organizations, MSA faces an increasingly dynamic business environment — including global supply chain constraints — even as we continue to work to meet customers’ needs for premium-quality personal protection equipment. We have concluded that we will not be able to offer our Abrasi-Blast Respirators with Advantage 4000 Facepiece (model reference 4300 S/H) for the foreseeable future.

As an alternative, consider our Abrasi-Blast Respirators with Ultravue^® Facepiece. This series features three inlet pressure ranges: 10–15 psi, 35–40 psi, and the Duo-Flo^® option. 

Here are the impacted part numbers (inclusive of any special materials associated with these items):

• Complete assemblies: 10089177, 10089210, 10116961, and 10116962 
• Facepiece assemblies: 10065323, 10089110, 10089112, 10089150, 10089152, 10089154, and 10089160 

We apologize for any inconvenience this change may cause your business. If you have any questions, please do not hesitate to contact our local sales or customer service representatives.
