FLEXIBLE AIR DUCT SYSTEMS Insulated and Non-insulated

MOD. PP

Is fabricated with a galvanized spring steel helix wire, encapsulated in a continuous double layer of resistant polipropilhene film. It is air-tight and wil not balloon or colapse.

I.D. Sizes: 3" through 6" in 1" increments, 8" through 20"in 2" increments.

Working Pressure: +10 in.wg.Max.

.......................

MOD. AL

Is fabricated with a lightweight aluminum alloy, resists corrosion an metal fatigue. Helical convultions gives high resistance to crushing and damage. Will not absorb moisture, noxious fumes or odors. Self supporting-will not sag or bunch up in bends. Low cost system for A/A supply or returns ducts. Enginereed for use in low pressure and high pressure systems.

I.D. Sizes: 3" through 6" in 1" increments, 8" through 20" in 2" increments

Working Pressure: +16 in.wg.Max.

MOD. DA

Is fabricated with a galvanized spring steel helix wire encapsulated in a continuous double layer of Foild Scrim Kraft (FSK).

I.D. Sizes: 3" through 6" in 1"increments, 8" through 20"in 2"increments.

Working Pressure: +16" in. wg. Max.
