NOZZLES FOR MOST ANY HYDROSEEDER
Nozzles are sized in three ways. One is the size of the body such as a 1″ nozzle or an 1 1/4″ nozzle. As an example the body size of a 1″ nozzle will be 1″ in diameter with 1″ male threads to screw into the gun. The second way is the angle of the spray which will usually vary from 80 degrees to zero degrees and the third way is the flow rate which is basically the size of the opening in the nozzle.
Our nozzles will work or can be adapted to work with most any hydroseeder. Typically as far as the size of the nozzle body we usually go we usually go one quarter inch smaller than the inside diameter of the hose or smaller. In other words with a hose with an inside diameter of 1 1/4″ we will typically supply 1 inch nozzles or smaller. With a hose with an inside diameter of 1 1/2″ we will typically go with a 1 1/4″ nozzle or smaller.
NOZZLE SPRAY PATTERN
Nozzles for hydro seeding typically come in a range of spray widths. Typically they are available with spray widths that vary from 80 degrees to zero degrees.
FOR GENERAL HYDRO SEEDING
60 to 80 degree flat fan nozzles.
Typically the main nozzles used for hydro seeding will be a wide flat fan spray that ranges somewhere between 60 and 80 degrees. These nozzles make it easy to spray quickly and evenly. Generally you can trim pretty easily with these nozzles by just reducing the flow by partially closing the gun valve.
20 to 50 degree flat fan nozzles
These narrower spray nozzles will spray further than the wider nozzles. These are great nozzles for hillsides or when extra distance is required. Some people do like these as a general hydro seeding nozzle and they are also excellent for trimming.
Zero degree and fire hose nozzles
These nozzles basically spray a straight stream. The give the most reach of any hydro seeding nozzle and are great for tall hillsides and when you need to reach further than you can reach with a fan nozzle. It is slightly more difficult to get an even application but with a little practice moving the spray back and forth will allow you to apply the material fairly evenly.
