INSULATED FLEXIBLE METAL AIR DUCT

V-200-UL \ V-200-S-UL

Description
Insulated, high pressure, Metalflex® aluminum air duct. Designed to connect truck duct to air distribution terminals wher fire safety is extremely important. Sections are 8' long and compressed (V-200-UL) to 32" for better storage and handling or "S" straight, non-compressed sections (V-200-S-UL). Both versions utilize V-100-UL \ V-100-S-UL as the inner core. Factory insulated to standard code specifications and covered by a tough gray polyethylene vapor barrier. Each end has a factory installed universal male/female collar. Our superior design helps eliminate flattening on the outside radius of a bend thus preventing restricted air flow.
