{"Image DocumentName": "PARTICULATE MATTER - THE ROLE OF INSULATIONS", "Image ImageDescription": "External duct insulations should not contribute to dust levels in the occupied space. Internal duct insulations are designed to be non-contributors when properly installed. FG duct liners are tested at 2.5 times rated velocity, including an elbow without vanes, to assure that they can withstand air velocity abuse. numerous studies have shown fiber levels to be at background levels.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
