I bought it for a vacuum chuck of a small lathe. I could use it as a filter without problems. Below difficulties When moving the hose, it often happens that the joint for filter replacement on the main unit comes off. It broke at half a year because of the load on the joint. It seems that the whole is made of plastic and there is not much rigidity. I think that it would be better to take out a little more money and buy the same Pisco's VFR 20. This is a firm making.
