3M? Cool Flow? Valve - 1

3M™ Cool Flow™ Valve Cool comfort starts with cool breathing The proprietary 3M™ Cool Flow™ valve is designed to release your hot, humid exhaled breath quickly, helping to prevent an unpleasant build up of heat inside the facepiece - a significant cause of discomfort to respirator wearers. The Cool Flow valve’s efficiency in keeping breathing cool and comfortable has been demonstrated through testing*: the atmosphere inside a respirator with a Cool Flow valve is on average 7.5°F cooler than the similar product without the valve. This makes Cool Flow valved respirators ideal for long periods of wear, especially where conditions are hot, humid or physically demanding. To learn more and see the Cool Flow valve in action, visit 3M.com/CoolFlow. Thermographic images (above): top: 3M™ Particulate Respirator 8510, N95, unvalved; bottom: 3M™ Particulate Respirator 8511, N95, with the Cool Flow valve. * Testing conducted in a 3M laboratory. Testing protocol, data generation and conclusions were reviewed and approved by an expert from The University of Minnesota. The testing performed by 3M is not a part of the testing and certification conducted by NIOSH.
