The RespAir welding helmet with built in respirator comes complete with the following features and options
This welding helmet respirator type protects against particulates but not against toxic gases or vapors. Filtering facepieces rated at N-95 provide a minimum efficiency of 95 percent for particulates free of oil.
These filters are available in three classes: N, R, and P, and three efficiencies: 95, 99, and 100. Any R or P filters can be used for any particulates, including those in oily environments.
A clean welding respirator is a healthy respirator. Welding helmet respirators which are not properly maintained loose up to 50% of their effectiveness. There are many ways to clean your respirator including disinfectant strips. However an automated process called the RespAir has been proven to be 99.9% effective and safe.
The reusable half-mask welding helmet has an inhalation valve to keep the filter dry and allows you to perform a positive pressure seal check. A stainless steel mesh cover on some welding versions protects you from heat, sparks, and slag.
This welding respirator type is designed to protect against specific gases, vapors, and particulates when their concentration levels exceed the PEL or TLV, but is below the concentration level that requires a full-facepiece air-purifying respirator.
This welding helmet respirator provides eye, face, and respiratory protection in non-IDLH environments. Many full-facepiece welding respirators are designed with a flip-up welding lens; some also have a flip-up welder's shield that covers the respirator's complete lens and releases to provide even wider range of vision.
It enables filters and cartridges in air-purifying respirators to be placed outside the heated plume of welding gases, vapors, and particulates. Extension tubes enable you to place the filter elements in a pack on your back instead of on your facepiece.
These welding helmets are available with either a half or full facepiece that connects to a source of breathable air with an air supply hose.
Self-contained breathing apparatus (SCBA) or a pressure-demand air-line respirator (PDAR) with emergency escape cylinder is required in IDLH areas.
