s nd | has anyone tried the pre-orifice tips? Saw them spraying at a meeting in moorhead mn couple weeks ago. Very even medium pattern with little drifting and more consistent across the whole pattern. I can't use ai tips in some of my spraying, as I need more coverage than they provide, but they have their place. They say they are a bit harder to clean in the field, so carry a few spare. Can of air was recommended. I was really impressed with how it looked and could take the place of both the flat fan and the ai tip.
Drift-Reduction Nozzles
Pre-Orifice Nozzles. A pre-orifice nozzle reduces the internal operating pressure in the nozzle, producing a larger spray droplet than a standard flat-fan nozzle at the same operating pressure. The pre-orifice design contains a metering orifice (pre-orifice) that restricts the amount of liquid entering the nozzle. This is what drops the pressure within the nozzle.
Pre-orifice nozzles are available in 80° and 110° discharge angles with a general pressure range from 30 to 60 psi. The nozzle has a narrower pressure-operating range, as compared with a conventional extended-range flat-fan tip. Pressure should not drop below 30 psi, due to the internal pressure drop in the nozzle, or exceed 60 psi, as considerable driftable fines may be produced. The optimum pressure for this nozzle is 40 psi. Pre-orifice nozzles can reduce drift by 50% over extended-range flat-fan nozzles, but they are more difficult to clean due to the metering orifice. Several manufacturers make nozzles using
