Round, Oval & Double-Wall Duct

• PAR, Inc. manufactures four-ply spiral lockseam and welded longitudinal seam ductwork.
• Both are manufactured in round and flat oval (for restricted space applications) configurations in single-wall, lined or double-wall.

The unique attributes of Spiral duct (whether round or oval) can reduce installation costs:

• Easier to install through and around structural framing.
• Longer spans reduce installation operations and the number of connections and hangers required.
• Connections are made quickly and are easier to seal.

Spiral duct reduces upfront and operating costs:

• Low air leakage, optimal airflow characteristics, and less pressure drop allow smaller and more efficient air moving equipment.
• Inherently stronger, allowing the use of lighter gauge, less costly metals.
• Efficiently manufactured from strip steel to any diameter.
• Spiral duct's smooth interior traps less dust and is easier to clean.

Spiral duct is available in many materials to meet a broad range of applications:

• Galvanized
• Electro-galvanized (Paintlock)
• Poly-vinyl coated steel
• Aluminum 3003
• Stainless 304 or 316
• Black Iron
