La description

This Class 0 Air Duct is constructed of a special aluminum alloy that prevents corrosion and metal fatigue. The machine fabrication produces a continuous lock seam that permits the duct to be pulled open, compressed, bent and re-bent without developing leakage. This duct will not delaminate or dry rot when heat aged. It can be installed with severe bends and in unlimited lengths while maintaining an unrestricted diameter. The product comes in conveniently boxed 5 foot, *0 foot and *5 foot lengths. It is compressed to nearly 3 times its original length for convenient shipping and handling. Applications SM Aluminum Flexible Ducting can be used in a number of applications including: Heating air Conditioning, Exhausting and Fresh Air Intakes Ideal for use in clothes dryer, bathroom and kitchen exhausts. Features Benefits Totally non-combustible Maximum operating temperature **5ºF Can be bent into any configuration No need for elbows Near zero permeability and leakage Reduces energy loss Will not sag between 6 foot supports Easy installation Performance Data Flame Spread : Zero Smoke Developed : Zero Temperature Range : **0°F to **5°F Maximum Velocity : ***0FPM 3" to *0" Diameter Static Pressure – positive : *2” ***** Static Pressure – negative : *2” ***** *2" to *0" Diameter Static Pressure – positive : 8” ***** Static Pressure – negative : 8” ***** Permeance : Near Zero Max.
