This high-pressure, 5-gallon capacity sprayer from Solo reaches a controlled operating pressure of up to 435 PSI, even at extreme heights. Thanks to its push-pull piston pump, the powerful Honda mini 4-stroke engine delivers a minimum flow rate of 0.5 gal./min. at 435 PSI. A drain connector at the bottom of the tank enables liquids to be drained completely. This sprayer is equipped with high-quality dual flat fan jet nozzles and stainless steel nozzle screens and has a heavy-duty shutoff valve with pressure gauge.
