Additional Accessories

High Pressure Strainer 
The high pressure strainer is mounted between the pump and the reel. It is easily cleaned by means of a flush valve mounted on the bottom of the strainer body. The strainer eliminates the need for repeated cleaning of your gun nozzle by removing contaminants before they reach the spray gun.


Hose Roller Guides
Roller guides can be easily added to the sprayer to assist in pay-out and rewinding of hose. Hose roller guides help keep the hose off the side of the vehicle.

Modular Tanks
An inexpensive way to increase capacity and/or provide for a second spray solution. Available in 35-,50-,100-, 150-, 200- and 300-gallon capacities. The modular tanks come complete with suction and agitation lines, 3-way ball valves, hose and clamps.
