The Super Max ® 8900C-525 is commercial industrial gasoline powered cold water pressure washer, powered by a 10 HP gasoline engine. The 8900C-525 offers a higher flow rate (5 GPM) and pressure (2500 psi) than the 8900C-322. Two gun operation is available on the 8900C-525, in addition to the same wet sandblasting system available on the 8900C-322. The Super Max ® 8900C-525 gasoline powered cold water pressure washer is ideal for outdoor applications, or those that require the use of a gasoline powered machine over an electric pressure washer, but that require more power than that available on the 8900C-322.
