+1 (978) 295-7538JP-3504-3MMB Gas Pressure Washer — JP Series 3500 PSI with Mi-T-M OHV Engine
The JP-3504-3MMB produces 3500 PSI at 3.5 GPM — 12,250 cleaning units — from a 420cc Mi-T-M OHV engine paired with an AR crankshaft pump. The JP-3504 is the entry to Mi-T-M's high-output JP Series; at this output level it handles fleet washing, agriculture equipment, and property maintenance work that stalls lighter 3000 PSI units. Buyers choosing between the 3MMB (Mi-T-M OHV), 3MHB (Honda GX390), and 3MKB (Kohler CH440) variants get identical frame, pump, and accessories — the only difference is the engine and its authorized service network.
JP-3504-3MMB Cleaning Output and Engine Comparison
At 12,250 CU the 3504 frame outpaces the JP-3003 (9,000 CU) by 36 percent, enough to meaningfully reduce rinse passes on large surfaces. The Mi-T-M OHV engine suits buyers whose preferred repair shop stocks Mi-T-M parts or who want uniform engine inventory across a multi-unit fleet.
- 3500 PSI at 3.5 GPM (12,250 CU) — removes heavy mud, road film, and oxidized paint from equipment without multiple passes
- 420cc Mi-T-M OHV engine — direct factory parts support; matches fleets already running Mi-T-M power equipment
- AR crankshaft pump, forged brass manifold — crankshaft geometry handles sustained daily operation better than axial designs
- Thermal relief valve and in-line water strainer — protects pump from heat build-up when trigger is held closed and from particulates in supply water
- 50-ft × 3/8-in non-marking hose, 48-in lance — longer lance reduces back strain; 50-ft reach covers most trailer and box truck lengths
- Powder-coated steel frame, 10-in flat-free tires — withstands job-site impact; tires never need inflation mid-shift
JP-3504-3MMB Applications and Environments
Fleet maintenance operations use the JP-3504-3MMB to wash trucks, trailers, and construction equipment where 3000 PSI units leave road film on heavily soiled undercarriages. Agricultural producers wash combines, sprayers, and grain trailers at season end. Property maintenance contractors clean parking decks, loading docks, and building facades. Municipalities apply it to street sweeper washdown and vehicle yard cleaning. Construction firms use it for concrete form cleaning and equipment prep before painting.
