Choosing Nozzles

FIXED WING AIRCRAFT

When making decisions about which nozzles to use, several things should be considered:

  • Airspeed, Swath
  • Droplet Spectrum
  • Gallons per Acre

CP-11TT’s are the most versatile nozzles for the full range of airspeeds. In most instances, flat fan tips offer the best drift control and narrowest relative spans. The wide range of tips styles available make both large and small droplet spectra possible. Nozzles are set up with tips meeting the specific needs of each aircraft. Tips are color coded for flow rate and click into place with a detent spring and ball.

CP-06 Swivels, used with CP-11TT flat fan nozzles, make it possible to adjust the nozzle downward into the airstream at 15° increments. These adjustments create the smaller droplet spectrum needed for insecticides and fungicides.

   

CP-07’s and CP-09’s are nozzles with four orifices (0.062, 0.078, 0.125 and 0.172) and three-way deflectors with a straight stream setting and 5° and 30° deflection. These nozzles were designed for aircraft flying at speeds of 130 mph and higher.

CP-03’s, the original aerial nozzles, work well for airspeeds of 120 mph or less depending on the application. At higher airspeeds, these nozzles will produce more driftable fines than CP-11TT’s or CP-07/09’s. They have the same four orifices as the CP07/09’s but the deflector angles are 30°, 55° and 90°.

ROTARY AIRCRAFT

Generally, the challenge with rotorcraft is producing a droplet spectrum small enough to be effective for insecticides and fungicides. While drift control is critical for many applications, producing the droplet spectrum needed is less problematic.

CP-11TT’s, with the wide selection of flat fan tips, offer the most versatility. There are 40° and 110° flat fan tips available. Spray nozzle models which calculate droplet spectrum are available for all tips.

CP-03’s, the original CP° nozzles, work well for rotorcraft. The four orifices and three deflector planes offer many choices depending on the aircraft and product being applied.
