Cool comfort 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 This makes Cool Flow valved respirators ideal for long periods of wear, especially where conditions are hot, humid To learn more and see the Cool Flow valve in action, 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.

Cool comfort starts with cool breathing The proprietary 3M Cool Flow Valve TM TM Expel Unique proprietary design • seals during inhalation • asily opens during e exhalation Aerodynamically designed valve cover • irects airflow away from your d eyes and face to help reduce eyewear fogging Putting the hot air about respirators to the test 3M develops respirators with your comfort in mind. But it doesn’t stop there. The test, developed internally by 3M, is performed using a breathing machine. Until now the only way for wearers or specifiers to determine how hot a respirator feels on the face (one...

Cool comfort stans with cool breathing The 3M " Cool Flow " valve is only available on 3M respirators 3M has a wide range of NI0SH 42 CFR 84 approved filtering facepiece respirators, both unvalved and valved. To see a filmed demonstration of the 3M Cool Flow valve, visit: www.3M.com/CoolFlow. All 3M Filtering Facepleces are NI0SH approved respirators. Before using, you must determine the following: 1. The types of contaminants for which the respirator Is being selected and exposure time. 2. The concentration level of the contamlnant(s). Do not use for particle concentrations that exceed 10 times...
