The JP-4004-3MHB is the highest-output model in Mi-T-M's JP Series, producing 4000 PSI at 3.5 GPM — 14,000 cleaning units — from a 389cc Honda GX390 OHV engine paired with an AR crankshaft pump. At 14,000 CU it delivers 56 percent more cleaning power than a standard 3000 PSI / 3.0 GPM unit and is ETL listed for US use. Buyers comparing the 3MHB (Honda GX390) variant against lesser JP models should note this is the only JP-4004 configuration; at 4000 PSI the AR pump requires the GX390's displacement to maintain rated flow under sustained load.
At 14,000 CU the JP-4004-3MHB handles jobs that exceed the capacity of 3500 PSI units — stripping loose paint from concrete block, washing enclosed trailers that carry livestock or agricultural product residue, and cleaning large building facades in fewer passes. The Honda GX390 is factory-recommended for commercial equipment at this output level and is the engine choice for buyers with established Honda dealer service relationships.
Industrial cleaning contractors use the JP-4004-3MHB where 3500 PSI units leave contaminant behind — paint prep on concrete and masonry, washing heavily fouled livestock trailers, and cleaning chemical plant exteriors. Fleet operations that service tanker trucks and bulk carriers benefit from the 14,000 CU output when stripping road film from large surface areas in a single shift. Property restoration companies use it on building facades before coating application. Municipalities apply it to graffiti removal from concrete and masonry where lower-output washers require chemical pre-treatment to compensate.
Rated at 3.5 GPM at 4000 PSI (14,000 cleaning units) at rated flow. Includes quick-connect nozzles in 0°, 15°, and 25° patterns; 50-ft × 3/8-in non-marking high-pressure hose; 48-in lance with insulated trigger gun. Cold water only. 49-state engine — not for sale in California.
