A Spiral Duct offers you a cylindrical design with outside ridges. Spiral Ducts are useful for limiting noise and require less space than rectangular ducts.
Double Wall Spiral Ducts
A Double Wall Spiral Duct offers a similar design to our Spiral Ducts, except the dual-wall design offers the purchaser increased noise reduction.
Flat Oval Ducts
Our Flat Oval Ducts feature an elliptical shape and offer a larger surface area than our Spiral Ducts while retaining noise-reduction qualities.
A Rectangular Duct is a traditional style found in many buildings. Rectangular Ducts offer a classic look and also offer good height clearance.
If your needs are more specific, AMW can fabricate a custom duct that meets your exact specifications.
