I have alor of these, so if you are interested i. Buying 10 or more, I will sell them for $110 a piece.  Willing to make deals on 3 or more  as well.   Just message me and I can create a separate post. The VMD-30 is a wall mountable Air dryer unit. It can supply up to 30 l/min of dry air under normal conditions. The VMD-30 is used to supply a dry air source for as many as two VMUS-K3 Ozone Generators. This is ideal if an application using smaller units where expansion is being considered, or for larger units. 3 year factory warranty on this product.
