The first products A.P.I. manufactured were circuit accessories, but for long time most of products in API catalogue such as valves and cylinders were manufactured elsewhere. This state of things had a brake in year 1999 when the decision of manufacturing our own product range was taken: property started investing in a qualified R&D and a modern manufacturing unit. In the year 2007, another manufacturing unit was established and it also works in different fields not only with pneumatics.
