One of the biggest problems during work with a respirator is the heat buildup inside. The warm air, exhaled by the user, can stay inside the respirator and contribute to fatigue. The 3M Aura 9332+Gen3 Respirators are equipped with two unique features that help to reduce the temperature inside the respirator.
Inhalation is the cooler part of the cycle; 3M’s Advanced Electret (Filter) Media (AEM) allows easy inhalation of the cooler external air through the respirator. As the wearer inhales, the air is pulled through the respirator and the surface temperature decreases.
The valve’s plastic cover retains some of the heat due to the composition of the material. As the wearer exhales the respirator is filled with warm, moist air. Exhalation; 3M’s Cool Flow™ Comfort Valve opens 37% easier than the original Cool Flow™ valve, allowing 36% more air, together with its natural heat, to be expelled more rapidly. As the hot exhaled air exits through the valve, the rest of the respirator remains cooler and more comfortable.
Thermographic imaging enables us to see the cooling effect of the valve on the surface of the product. The colors in the thermal images show the change in surface temperature during inhalation and exhalation.
updated, modern and stylish design with clear cover lets you see new technology in action Opens more easily and stays open longer than the original Cool Flow Valve, allowing more hot air out to reduce heat buildup and increase comfort Helps to minimize the risk of eyewear fogging from heat exiting through the media
