PAPR (powered air-purifying respirator) systems for painting and spraying provide clean, breathable air to workers where paint fumes and aerosol spray is present, including automotive painting and material preparation. Covers keep units clean of paint spray. PAPRs have a battery-powered blower that passes ambient air through a filter into the facepiece. Some systems also use a cartridge to filter vapors and gases. PAPRs allow workers to move freely and unrestricted because the filter and power source are worn on the body.
