The W-20SSHC Solvent Spray-All is a low volume "high concentrate" spray applicator that will produce strong dilution ratios for applying solvents, including D-limonene. Weaker dilution ratios are controlled with metering tips. This stainless steel venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend a high concentration of chemical concentrate into the water stream to create a strong solution. This accurately diluted solution is then projected through the discharge hose and fan nozzle as a uniform spray on to a variety of surfaces. With a flow rate under 1 gallon per minute, this unit can spray virtually any sized area or object slowly and completely with very little run-off.
