SYSTEM 5625 FLEXIBLE AIR DUCTS

Anco system 5625 flexible air duct is a very versatile air duct product capable of performing in a multitude of low to high-pressure residential or commercial HVAC applications. System 5625 is well suited for main trunk lines, supply and return lines, connecting lines, as well as runs to diffusers and room registers. As class 1 air ducts, there are no associated limitations for installed length unless limited by a code body.

System 5625 flexible air duct is constructed around Anco's "ULTRA 10" core. The core is wrapped with a thick blanket of thermally certified energy saving insulation. A protective seamless vapor barrier of 2 ply metalized polyester / polyester reinforced with scrim yarn then covers the core and the insulation. This provides you with a class 1 air duct material with certified thermal R-values.

Sizes include: 3", 4", 5", 6", 7", 8", 9", 10", 12", 14", 16", 18" and 20" diameters and lengths are 25'. System 5625 is available with fittings attached with UL 181-B tape and is packaged in either corrugated boxes or poly bags.

Code Approvals: This product meets or exceeds the requirements of most federal, state, and local codes including UL 181; NFPA 90A/90B; HUD/FHA Std 515; Standard Mechanical Code; National Mechanical Code; Uniform Mechanical Code; Florida Energy code; the Cities of Chicago and Yew York, etc. just to name a few. We recommend you always check with your local authorities when in question.

Vapor Barrier: Very durable, puncture resistant metalized polyester/polyester vapor barrier reinforced with scrim yarn that provides improved protection against UV light. The metalized vapor barrier is designed to match aesthetically with FSK board materials.
