Above. And beyond.
There simply is no better PCA layflat ducting available on the market today. RAMPTECH® Premium PCA layflat ducting from Sage Parts features the finest engineering, assuring the highest level of performance for the most demanding positive pressure applications.
Heat-sealed (welded) design, high resistance to external abrasion and ultra durable overall construction combine with flexibility to deliver everything you want in a top quality PCA layflat ducting product that meets UL94VTM-O standards. But that's not all. Unique spiral construction enables the addition of a military-spec scuff strip that protects the entire duct - reducing fatigue and resulting in incredibly long service life. Other vital advantages include an extended inner liner and elastic seals at connection points to minimize air loss, as well as excellent UV stabilization, and mold and mildew inhibitors.
The Outer Layer
The outer shell is comprised of VentaTex® 20XHDMW 3-ply, 20 ounce/ square yard (678 g/m2) high strength PVC fabric and black wearstrip that meets military specifications. To improve abrasion resistance, nine millimeters of high density molecular weight PVC is added to the external wear surface. The custom laminate is produced by compressing high strength, multidenier, uni-directional Ripstop polyester yarns between PVC films. Finished material thickness is 0.029 inches (0.737 mm).
The Insulation Layer
The middle layer consists of stitch-bonded polyester insulation similar to the high performance material found in cold weather clothing and camping
The Inner Layer
The inner sleeve is made of VentaTex® 11-1812 high strength material, and 11 ounce/square yard (373 g/m2), 3-ply PVC fabric VentaTex® 11-1812 is specially designed to eliminate delamination commonly found in other inner liners. It is constructed by compressing high tenacity, high density polyester yarn between PVC films. Finished material thickness is 0.017 inches (0.432 mm).
