The Super Max ® 12500 PE is a tri-mode propane powered and propane heated pressure washer that offers the same performance and features as the 12300 and 12500 GE, but runs on an 20 HP propane engine. Like the Super Max ® 12500 GE this pressure washer is ideal for applications for which an electrical outlet is not available. Additionally this model is ideal for those that prefer propane to gasoline.
