psi. The paint flow is controlled by a flow regulator set at 20 psi and back pressure regulator set at about 18 psi so that the diaphragm pump runs at 3-4 sec per cycle. The fluid flows through air-operated fluid regulators to a maximum of three spray guns. We find that the fluid flow will alter during spraying at the low flow rates. We are debating changing the fluid hose from the regulator to the gun from a 4-mm bore to 2-mm bore, the theory being that we will require more pressure for the same flow rate. The paint in question is medium solids content, approximately 40 percent, and viscosity of 78 sec using a DIN cup. K.F. A. Following your theory of stabilizing fow rate by decreasing the hose size and increasing pressure may work. However, there may be other problems such as a faulty fuid pump, faulty regulators and out-of-adjustment gages. Differences in viscosity could also account for the fow rates. You should also consider checking the viscosity of each can of paint before adding it to your system Rather than trying to solve this problem yourselves, however, your equipment salesman or service representative should be in your plant trying to solve it for you. When you bought the equipment you also paid for technical service, so I recommend calling the equipment supplier for help. n Clean Competitive Filter Dirty Paint Pockets Which filter would you change next? If you chose the dirty one on the bottom, don���t feel bad, �� because you probably haven���t experienced the Paint Pockets difference. Fact is, the clean, ���straight-from-the-box��� filter on the top will need to be changed much sooner than the dirty Paint Pockets�� filter on the bottom. �� Even after heavy loading, this Paint Pockets filter still has at least twice as much effective filtering life as the clean filter on the top. (By the way, these are actual photos without any fancy retouching.) A better way to calculate filter cost Savvy sprayers know that you have to measure filter life by the number of parts sprayed���not by the square foot. That���s �� where Paint Pockets exclusive, patented Diamond Pocket TM Technology delivers a clear advantage.
