Negative pressure versus powered air purifying systems negative pressure respirator face mask

Jan 29, 2017A negative pressure device depends on the operator to breathe through a filter to purify the air. It could be a disposable respirator, a half-mask respirator or a full facemask. The latter two devices could offer protection against particulates, gases, vapors or a combination of these, depending on the filters used.OSHA Respirator Requirements for Selected Chemicals negative pressure respirator face maskHalf-mask* supplied-air respirator operated in pressure-demand or other positive-pressure mode. < or = 100 mg/m 3 Full-facepiece supplied-air respirator operated in pressure-demand or other positive-pressure mode (e.g., Type CE abrasive blasting respirators operated in a continuous-flow mode). > 100 mg/m 3, unknown concentration, or firefightingOSHA Respiratory Protection ProgramNegative-Pressure Airflow Negative-pressure respirators draw air into the facepiece via the negative pressure created by user inhalation. The main disadvantage of negative-pressure respirators is that if any leaks develop in the system (i.e., a crack in the hose or an ill fitting mask or facepiece), the user draws contaminated air into the negative pressure respirator face mask

OSHA Technical Manual (OTM) Section VIII Chapter 2 negative pressure respirator face mask

An important aspect of respirator operation and classification is the air pressure within the facepiece. When the air pressure within the facepiece is negative during inhalation with respect to the ambient air pressure, the respirator is termed a negative-pressure respirator.PAPR vs. CAPR Respirators - What's the Difference?This is the upper limit at which a respirator is expected to provide protection. The positive pressure produced by a PAPR somewhat solves the problem of ineffective face sealing.
