Flooding nozzles produce coarse droplets with uniform distribution. Ideal for use with hand-held sprayers and application of soil applied herbicide and liquid fertilizers. Large circular orifice means resistant to clogging Less prone to spray drift

Poly-Jet

Wide angled flat flood spray Specifically designed for applications through hand-held sprayers over 1-3 bar Flow rates from 0.6 to 3.79 l/min Available in four different spray angles that give ground coverage of between 50 cm and 2 m at 50 cm boom height Can be used with spray shield to reduce spray drift

Deflect-Tip

Wide angled even spray 80-145° Wide range of nozzle sizes and application rates Ideal for band spray applications of Pre- and post-emergent herbicides Smaller sizes suitable for hand-held sprayers

Hollow cone nozzles produce a high velocity fine spray which swirls around in a cone pattern They give good target coverage and are therefore ideal for use with contact acting agrochemicals such as fungicides and insecticides and for penetrating dense canopies Also suitable for band and knapsack spraying

Hollow Tip 80° Ready assembled 2 piece nozzle Produces fine droplets at pressures from 3-6 bar applying from 8 to 200 l/ha depending on nozzle and forward speed selected

Hollow Cone nozzles Hollow Cone nozzles

These nozzles eliminate the finer droplets that are associated with conventional nozzles so reducing spray drift and allowing spraying in more marginal conditions when drift would be unacceptable with conventional flat fans

Traditionally they have been used for spraying against easier targets such as soil application and larger plants and weeds
