Oneida Air Systems is your one-stop-shop for all of your dust collection needs! We manufacture and sell a full line of round ductwork fittings built for maximum durability using heavy-gauge galvanized steel. Our ducting is designed to withstand the high suction pressures and constant friction created in dust collection and other material handling applications. Standard ducting components include snap-lock and spiral pipe fittings that must be crimped, coupled, screwed, or welded together.
