Recommended nozzles
Intermediate flow rates may be obtained by choosing the noz-
zle with a nominal flow rate slightly higher than that actually
required.
Complete range of nozzles:
?
Bergonzo tipo B5 60°:
250 - 275 - 300 - 325 - 350 - 375
- 400 - 425. We normally recommend 60° angles of pul-
verisation.

Fluidics tipo N2 50°:
250 - 275 - 300 - 330 - 360 - 400 -
450. We normally recommend 50° angles of pulverisa-
tion.
