Air-purifying respirators have APFs in the range 5–50 while SARs are in the range 25–2000, and full-facepiece pressure-demand SARs with an auxiliary pressure-demand SCBA have an APF of 10,000. For substances hazardous to the eyes, a respirator equipped with a full facepiece, helmet, or hood is recommended.
Air-purifying respirators range from relatively inexpensive, single-use, disposable face masks, known as filtering facepiece respirators, reusable models with replaceable cartridges called elastomeric respirators, to powered air-purifying respirators (PAPR), which use a pump or fan to constantly move air through a filter and supply purified air ...
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
See: venturi mask air-filtering respirator An air-filtering respirator is a breathing apparatus which removes particulates from the ambient air by passing it through a filter. air-purifying respirator An air-purifying respirator is a respirator which uses a filter, cartridge, or canister to remove specific air contaminants by passing ambient air through the air-purifying component ...
Semi-closed systems have a full boundary with the surrounding atmosphere, and use a controlled source for fresh gas flow. Intake of ambient air is prevented, but excess fresh gas is vented into the surrounding atmosphere. Partial rebreathing of exhaled gas can occur. They are commonly subdivided using the Mapelson classification (see below).
A powered air-purifying respirator (PAPR) is a type of respirator used to safeguard workers against contaminated air. PAPRs consist of a headgear-and-fan assembly that takes ambient air contaminated with one or more type of pollutant or pathogen , actively removes (filters) a sufficient proportion of these hazards, and then delivers the clean ...
