Fluid Handling/Dispensers Q&A

  •   Sometimes I get a slight variation in my deposit size. What could be the cause of this?

    There could be several causes, depending on what type of fluid you are dispensing. If you are dispensing a particle-filled material, you could potentially get some partial clogging in the dispensing tip, causing the variations. One of the most common factors to look for is your plant air supply. If you have fluctuations in the air line going into the dispenser, you will most certainly get variations in your deposit size. Make sure you have an in-line filter regulator between your plant air and the dispenser. If you do have plant air fluctuations, you should set the filter regulator approximately 5–10 psi lower than your lowest plant air fluctuation point.
