NONINSULATED AIR DUCT

V-100-UL \ V-100-S-UL

Description
Designed for use as a noninsulated supply/return air duct in return plenum ceilings or other areas with demanding fire safety requirements. This product is UL Listed as a Class 0 Air Duct in accordance with NFPA 90a & 90b. V-100-UL\ V-100-S-UL is noninsulated, high pressure, flexible aluminum, "Metalflex®", air duct. Factory installed universal male/female collars insure uniform, air tight connections. Our design allows for better stretching and bending characteristics. This helps eliminate flattening on the outside radius of a bend thus preventing restricted air flow. Metalflex® will not droop between 6' supports.
