MSHA approved Flexible Lay Flat Ducting systems are ideal for positive pressure applications. Seams and grommets are welded to be airtight, providing low airflow resistance.

Increased clearance at the back or pillar for travel ways.- Increased air volume by maximizing available space for duct.- Reduced drift size to accommodate ventilation and equipment.- Reduced waste tonnage for new development drifting.- Variety of size combinations, lengths and designs.-Woven Polyester/Nylon fabric with both sides PVC coated.- Low friction loss.- MSHA approved.-Flame resistance according to ASTM E-162 flame spread index less than 25 and EMR.
