Mira Safety MB-90 PAPR Powered Air Purifying Respirator

The MIRA Safety MB-90 is a detachable powered air-purifying respirator (PAPR) that turns a standard 40 mm NATO-threaded gas mask into a powered, positive-pressure system. Its blower clips to your belt or pack and supplies up to 90 litres per minute of filtered air through a hose to the mask, which makes breathing easier and takes the filter weight off your face. It's based on an Israeli military design and adapted to run on standard AA batteries.

Features

• Compatible with any traditional 40 mm NATO-threaded gas mask, including the MIRA Safety CM-6M and CM-7M
• Filters attach to the blower instead of the mask for improved mobility; it uses two 40 mm CBRN filters
• Positive pressure inside the mask can add a layer of protection around the edges of the seal
• If the batteries run out, the system reverts to standard negative-pressure breathing
• Runs on 8 x AA batteries (also compatible with NiMH and LiSO2) for up to 12 hours
• Impact-resistant polycarbonate housing with a slim profile for confined spaces
• Helps users with limited lung capacity who struggle with negative-pressure masks
