  1. Filter Mesh vs Micron

    Filter media is sometimes rated in U.S mesh and also in microns which makes life confusing for us all. It really comes down to where the filter media is made and which unit of measure the manufacturer chooses. 

    U.S mesh gauge standard is the number of openings per linear inch using standard wire diameters. Wire mesh measures the number of wires (or threads) per linear inch, not the size of the holes between them. As the number of wires per inch goes up, the size of the holes (in microns) goes down. 

    This chart below is a rough conversion between U.S Mesh and Microns as there is no simple formula to convert between microns and mesh because it can not account for the wire diameter.

  4. How does an electrostatic spray gun work?

    Electrostatic spray painting was first patented in the Harold Ransburg in the late 1940s after which he formed the company "Ransburg Electrostatic Equipment". 

    Electrostatic spray painting guns have an electrode located after the nozzle which charges the paint particles as they atomize, the charged paint particles will naturally attract to a grounded object when sprayed.

    Electrostatic spray painting increases transfer efficiency because charged paint particles will attract to the natural earth of the object being sprayed, in many cases the paint will actually wrap around the object reducing overspray, paint consumption and overspray.
