The National Personal Protective Technology Laboratory (NPPTL) requires repairs to its only 7000 psi breathing air compressor, which is currently broken and essential for respirator approval and audit testing. The contract's purpose is to repair the NIOSH-owned Bauer compressor (model VTC-7K/20) and return it to full operation. The scope is limited to the parts and labor needed for this repair. Performance of services will take place at the NIOSH Pittsburgh campus, specifically in Building 40. No budget amounts or submission timelines are specified in the description.
