Swiss Air PAPR


optrel's swiss air TH3 PAPR system is slim, ergonomic, and light as a feather. The core element of the respiratory system is a ventilated half mask that completely covers the mouth and nose area and constantly supplies it with purified air (according to TH3 standard). Breathing space is created in the mouth and nose area to support the user in breathing and eliminates tiring breathing resistance. In this way, the user is permanently in an "overpressure air system" which permanently protects his airways against contaminated air. The half mask, made of high-tech fabric, is designed so that it can be adapted to the individual due to a freely adjustable headband. This concept eliminates the need for time-consuming fit tests that are common with conventional half masks.


Clean air is supplied through the Y-hose by a miniaturized blower system, which is comfortably carried by the wearing unit on the back. The filter unit is 45 mm narrow and weighs just 550 g. The intelligent control unit completes the system. It can also be used with a construction/industrial helmet, weldCap or without a helmet at all.
