PAPR is a battery-operated respirator that purifies incoming air before a person breathes it in. It includes a battery pack, a motorized fan, filters, and a face mask or hood. PAPRs are used in industrial and commercial settings, by first responders and healthcare professionals to protect the wearer from inhaling harmful substances in the air.
An air purifying respirator (PAPR) is a battery-operated respirator that purifies incoming air before a person breathes it in. A fan blows the air through the filters contained in the cartridges. The clean air then flows into a mask, hood, or facepiece that covers the person’s nose and mouth. PAPRs are used in industrial and commercial settings and by first responders and healthcare professionals. Although the word “respirator” is already part of the PAPR acronym, the device is often referred to as a PAPR respirator.
A typical PAPR includes a battery pack, a motorized fan, filters encased in round cartridges, and a face mask or hood. The battery pack powers the fan. Blow incoming air through filter cartridges to remove contaminants. The purified air then enters the user’s breathing zone through a mask, hood or face mask.
The components of a PAPR can be configured in several ways. The battery pack, fan and filter cartridges can be combined into one unit which can be worn on a belt around the waist or as a backpack. A breathing tube feeds purified air to a face mask. This configuration is commonly used by rescuers.
In some configurations, the battery pack is a separate unit that can be worn on a belt. In this case, the blower and filter cartridges are incorporated into a facepiece or hood. A full facepiece covers the entire face. A half facepiece covers the nose and mouth, but not the eyes. The facepieces must fit tightly to the skin to prevent contaminated air from entering.
The purpose of an air purifying respirator is to protect the wearer from inhaling harmful substances in the air. Different types of respirators do this in different ways. An air-supplied respirator, also known as an air-supplied respirator, pumps uncontaminated air from outside the hazardous environment or from air cylinders carried by the respirator wearer. A PAPR cleans contaminated air by filtering it. Filter cartridges are custom designed for specific air contaminants.
A common PAPR filter captures and holds solid particles. This includes large particles, such as dust, and microscopic particles called particulate matter. Airborne particles are especially dangerous, because they can be breathed deeply into the lungs. Smoke from anything that burns contains particulate matter and can contain larger particles, such as ash.
In healthcare, filters are used that remove bacteria and viruses. Commercial and industrial occupations can include exposure to dust, fibers, molds, spray paints, and various types of chemical vapors. Rescuers typically use filters designed to remove smoke or specific chemical, biological, radiological, and nuclear contaminants.
