What is the ideal pressure range for flat-fan nozzles?

• A. 10-20 psi
• B. 30-60 psi
• C. 70-90 psi
• D. 100-120 psi

Answer: (B)

Pressure controls how big the droplets are and how the spray fan behaves. Flat-fan nozzles are designed to deliver a broad, even pattern, so operating at a moderate pressure helps maintain a stable, uniform spray and medium droplet size. This gives good coverage on turf and ornamentals without wasting product or causing excessive drift. If pressure is too low, the pattern can be narrow and coverage gaps appear. If pressure is too high, droplets become finer, drift risk increases, and the spray pattern can become less predictable, reducing effective coverage. Therefore, a middle-range pressure is preferred, and you should always follow the nozzle and product label to pick the exact pressure for your nozzle size, spray volume, and travel speed.
