ESAB Origa Air is not the same quality or as eloquent a design as the Adflo but is less than half the price. Seems perfectly OK for home/hobby use. It does what it says on the tin. Nivag
My current set up is a esab eyetech II with a adflo unit.
the air diffuser was taken from a earlier eye tech II,and the two units are joined using a modified 3m dustmaster hose.
