The 3M Versaflo Powered Air Range is a state-of-the-art positive pressure respiratory system - the powered air unit pulls the outside air through the filters and supplies clean filtered air up to your chosen head top. Each unit offers very high protection levels and comfort when compared to negative pressure half masks and full face masks and is a great solution for those with facial hair.
For particulates and mist protection have a look first at the TR-300 system. If you need protection from particulates, gases and vapors check out the TR-600 and finally if you are working in potentially explosive environments such as petrochemical industries or grain silos you will need to consider the TR-800 (approved to Zone 0).

The unit provides the very latest in Powered Air Purifying Respiratory technology, combining decades of innovation from JSP in the fields of respiratory, head, eye and face protection.
