SCM Sundström SR 500 / SR 570 Powered Air Purifying Respirator Kit - H06-6621
The SR 500 Fan Unit is a belt-mounted Powered Air-Purifying Respirator (PAPR) that connects to the SR 570 Face Shield. When used together, the SR 500 and 570 protect against particulates like saw dust and silica dust, as well as harmful odors and gasses (when used with the applicable chemical cartridges).
The SR 500 PAPR system functions as an alternative to Air Purifying Respirators (APR). The powered battery pack provides automatic air flow control, keeping the user safe. The same control is used for starting, stopping, and selecting an operating status for user convenience. The SR 500 can operate at two levels: normal (6.2 CFM) and boosted (7.9 CFM).
The SR 570 is a robust shield with a flip-up visor that provides comfortable and safe respiratory and eye protection. Well-balanced and lightweight, the head hardness offers several adjustment options for the best fit. The SR 570 features an air flow deflector for more comfort, as well as an exhalation valve that reduces the carbon dioxide content in the shield.
Two HE particle filters are included in this kit. These filters provide protection against all types of particulate pollutants and should be used with SR 221 pre-filters. As mentioned above, the particle filter can also easily be combined with Chemical Cartridges in order to provide protection also against gases and vapors, e.g. during spray painting.
