The Super Max™ 12840 has pressure levels of 2000 psi and flow rates touching 4 GPM. This machine can be trailer mounted for easier operation, but electric powering may hamper large-scale outdoor use. High pressure washers designated for outdoor use should typically be gasoline propane powered. This is convenient when you are operating the machine without access to electric power.
Daimer® does offer high pressure washers that run on gasoline or propane for enhanced mobility, as well. Consider the Super Max™ 12880. This highly powerful machine can reach pressure levels of 3000 psi, flow rates of 5 GPM, and temperature of up to 330°F.
