Powered air-purifying respirator (PAPR)
Bio-Medical Devices International
For respiratory protection against airborne particulates
Approved by US National Institute for Occupational Safety and Hazard (NIOSH), and Occupational Safety and Health Administration (OSHA)
MAXAIR® Controlled Air Purifying Respirator (CAPR®) system is advanced respiratory protection equipment approved by the US National Institute for Occupational Safety and Hazard (NIOSH) for protection against aerosolised and airborne particulates.
Developed by Bio-Medical Devices International, the equipment has become the respirator of choice for various healthcare organisations amid the 2019-n-CoV coronavirus outbreak for standard protection of the healthcare professionals as per CDC guidelines against COVID-19 during the coronavirus treatment.
The personal protective equipment (PPE) has also seen approval by the US Occupational Safety and Health Administration (OSHA).
MAXAIR CAPR system design and features
MAXAIR CAPR is a compact, light-weight, computerised, no-hose powered air-purifying respirator (PAPR), whose highly-integrated design avoids the need for large air tubes and heavy belt-mounted blower units present in conventional PAPR.
The system contains four primary components, a helmet with power cord, battery, belt and charger. Various components, fan, filter, airflow system and motor, are also integrated. The filter cartridge is housed in the helmet, while the filter cover cap (FCC) is securely placed over it. Headband adjustments are positioned for secured wearing.
Airflow switch on the helmet adjusts and operates airflow. Disposable lens cuff (DLC) is placed around the face by fixing it to three attachment points on the helmet. DLC is a full-face cover with a high assigned protection factor (25).
The LED indicator of the helmet alerts the user for the equipment maintenance in real-time, and a lithium-ion battery clips onto the battery belt, adjusted around the waist. The system comes with two battery options.
The 2000-36 battery offers a run time of eight to ten hours, while the 2000-30 battery ensures the system to operate for a maximum of 20 hours. Helmet power cord is connected to the battery by cord connector.
Shroud and hood configurations with an assigned protection factor (APF) 1000 allow full head and neck coverage.
MAXAIR CAPR respirator technology
Equipment filters large and small particulates with high efficiency, with many penetrating particle sizes (MPPS) of 0.04μm to 0.06μm.
Filtration particle size encompasses dust, bacteria such as Mycobacterium tuberculosis, anthrax and Staphylococcus aureus, as well as viruses such as coronavirus, HIV, hepatitis and cytomegalovirus. It combines electrostatic and mechanical filtration technologies to deliver higher filtration efficiency.
Functioning of MAXAIR CAPR system
The user pulls the air inside the equipment through the filter, which gets distributed around the face gently. Positive pressure is maintained in the helmet, which facilitates easy breathing without heat, moisture and carbon-dioxide build-up and lens fogging.
The system prevents the inhalation of contaminated air and requires no fit testing as the negative pressure respirators. It also eliminates facial pressure points.
A blower controlled by micro-computer facilitates the adjustment of airflow at the desired level by the user according to their activity level.
Benefits of MAXAIR CAPR
No-hose MAXAIR respirator eliminates the chance of snagging, optimising ease and freedom of movement due to the absence of bulky blower units. System configuration can be conveniently changed into a cuff, shroud or hood.
The system simplifies de-contamination and avoids the need for following rigorous cleaning procedures. The non-claustrophobic device ensures accurate fit during real-time working conditions to ensure overall comfort and non-interference to healthcare professionals during activities.
New versions of hoods, 2271PB-07 Single and 2272PB-07 Double, provide extra protection under the ASTM F1671 standard test method for protection against blood-borne pathogens.
The configuration allows a full and clear field view for unobstructed communication with patients.
