Divair 1956 #2715

The Divair two hose regulator first appeared in 1954, my model is a bit strange as it doesn’t have the hope page mouth piece but a metal one. The Divair was discontinued around 1957 which makes the quite rare. Very simple upstream one-stage design that is different enough from the Voit Sportsman or a USD StreamAir to avoid any patent infringement problems. No venturi assist, but the air is directed right down the intake horn without much spillage into the rest of the can.
