<p>Optrel Swissair Half Mask TH3 PAPR Backpack System
Giving the freedom you need with the Optrel Swissair Halfmask. The mask covers the mouth and nose and supplies them with fresh, clean air continuously. Resistance using this mask is low which prevents fatigue and ensures supported breathing. High tech fabric makes up the majority of the mask and is fitted to the user by the adjustable headband. This fits a wide range of users and reduces the need for time consuming fit testing.&amp;nbsp;
The Y hose carries the clean air from the miniature blower system from the backpack to the users nose and mouth. This is completed through a positive pressure system which protects the user from any contaminated air.&amp;nbsp;

The weight is ergonomically distributed using a shoulder harness to support the super-light filtration system, which weighs a total of 550g width of 48mm allows you to get into the tightest of spaces.&amp;nbsp;
The TH3 filtration unit is innovative and ultra flat to improve portability and allows efficient use.&amp;nbsp;
The blower unit has calibration sensors and has a 14 hour battery life which allows uninterrupted working day.&amp;nbsp;&amp;nbsp;
3 blower settings- can change the settings to fit your breathing needs 100-130 l/Min
This system is independent of helmets and any other equipment and provides the best and most versatile solution to respiratory system. The half mask can be used with a construction/ industrial helmet,&amp;nbsp;weldCap® or without any helmet.

The vegaview2.5 is perfectly combined with the optrel e3000 PAPR respiratory system. With its integrated high-performance particle filter (TH3), welders are adequately protected against smoke, aerosols, and dust
