Spray nozzle tip

Airless Tip orifices are elliptical in shape. The term "equivalent orifice diameter" refers to a circular orifice diameter which will provide the same flow rates as the elliptical orifice. The equivalent orifice diameter does not indicate the actual orifice dimensions. The flow rates of Delavan Airless Tips are given in US GPM based on water at the pressures shown. Capacities would vary to some degree on other liquids. The pattern width dimension is the nominal pattern width of each Airless Tip when tested on a coating material of 20 seconds - #4 Zahn cup viscosity at 1500 PSI at a distance of 12" from the Tip.
