Start Fast. Spray Hard. Repeat.
Meet the AR45H-E, our electric start gas-powered softwash system built around the elite AR45 diaphragm pump and a Honda GX160-200. It brings the pressure, the volume, and now — the push-button ignition that makes your crew actually want to start their day.
Engineered for roof cleaning, siding washes, and high-volume rinse work, this setup cranks out up to 11.4 GPM at 290 PSI, with smooth gear-driven power and precision control via bolt-on regulator and pressure gauge.
All of it? Sitting on a compact 14" x 20" aluminum skid frame that doesn’t flinch at the back of your rig.
