Product HighlightsSpiral pipe has a smooth interior resulting in low friction and less dust collection ands it's easier to install through and around structural framing. It is available in 10' lengths, reducing the number of connections required which means low air leakage and less pressure drop so the unit can run more efficiently. The strength of spiral pipe allows for the use of lighter gauges. Larger sizes are corrugated for added strength and rigidity.
