Flat Oval Spiral Pipe & Fittings for Commercial or Industrial Ductwork. Flat oval single wall duct and fittings from Sheet Metal Connectors, Inc. are one part of our complete line of HVAC products. Flat oval duct has been designed for restricted space conditions that cannot accept round spiral duct.

A double-walled insulated Flat-oval Spiral Duct consists of an external pressure tight metal shell, a 12.5 / 25 / 50mm thick of fiberglass / mineral wool / puf Insulation and Internal plain protective metal liner for thermal insulation or perforated metal inner liner for acoustic Insulation.

A specialised kind of ducting used in HVAC (Heating, Ventilation, and Air Conditioning) systems is spiral seam flat oval duct. The flattened oval design of flat oval ducts, in contrast to standard circular ducts, enables them to fit into smaller locations while still providing effective airflow.

Specifically designed to insulate rigid or semi-rigid round ducts, it is an excellent method for reducing heat or cool loss and condensation build-up. The sleeve is made of a thick fiberglass insulation blanket enclosed in a strong, fiberglass-reinforced silver metalized outer jacket.

Saddle mounted spiral duct diffusers. Aluminum finish. Single deflection. Includes saddle curved to fit duct radius and air scoop.

Flat oval duct provides a more efficient alternative to rectangular duct in applications where space is restricted. McGill AirFlow manufactures flat oval duct with the same techniques used to make round duct.

With 40 years of experience in manufacturing HVAC ductwork solutions, SAFID offers a superior line of quality ducts including round, oval, rectangular, flexible and double wall ducts and fittings.

HVAC diffusers install onto the ends of ducts and help spread conditioned air throughout a room. Some diffusers feature vents that create smooth airflow that travels along walls and ceilings before mixing with the interior air.
