Product Description

The John Bean 785 Tree Spray Gun (5253228) is a must have for tree care professionals who need to achieve maximum spray height from their tree sprayer.

Equipped with a long stainless steel barrel, the John Bean 785 FMC Spray Gun provides accuracy when spraying shrubs, plants, and tall trees. At the end of the barrel is a spray nozzle that can adjust from a fine round mist to a straight stream. The fine mist is suitable for close, tight spraying, while the solid stream is great for reaching tall or distant targets. With the John Bean 785 Tree Spray Gun, you'll be able to achieve a maximum flow of 48 GPM and a maximum pressure of 800 PSI, while being able to spray up to 10' high.

This high-pressure spray gun uses a straightening vain before the fluid exits the nozzle. As the fluid passes through the hose and exits the nozzle, the fluid will roll. This rolling action enables the spray pattern to break up earlier than a straight flow would.

Optimal performance of this John Bean FMC Tree Spray Gun depends on the pump capacity, pump pressure, correct nozzle selection, and feed hose diameter and length.
