Oval Duct is an economical option when space constrains prevent the use of round duct. Oval duct still offers favorable pressure loss coefficients compared to rectangular duct. Its uniform appearance makes it a better choice than rectangular duct for exposed applications. L&L fabricates single wall and double wall oval duct. For sizes, please refer to our duct sizes table below. For special requests and larger minor axis we offer long seam oval duct.
