Exposed Duct—
Product Line

McGill AirFlow supplies a complete line of round, flat oval, and rectangular duct and fittings. With our standard product line and custom fabrication capabilities, we can help you meet your design requirements. Because most exposed duct systems are painted, our standard duct material is paintable galvanized steel. Special duct materials are also available, including stainless steel and aluminum. We can provide samples to show you exactly what you will be getting.

For exposed applications, round or flat oval UNI-RIB® spiral duct is the most visually appealing. When the spiral seams are aligned, it gives the appearance of a continuous length of duct. Our UNI-SEAM™ ribbed elbows match the appearance of ribbed spiral duct. We can add to the continuous look by reducing the number of duct joints. One way is to fabricate long sections of duct: 20 feet or more for round spiral duct. Another way is to supply manifolds with built-in taps instead of using separate fittings. We can design the manifolds so that all spiral seams line up when installed.

Duct connectors, hangers, and reinforcements are a necessary part of any duct system, and we can work with you to develop special designs that minimize their use or make them as inconspicuous as possible. Insulation is often needed for thermal and acoustical control, but it does not have to detract from your visual design. Our single-wall, insulated and ACOUSTI-k27® double-wall, insulated duct have the same external appearance as standard spiral duct.
