+1 (978) 295-7538JP-3504-3MHB Gas Pressure Washer — JP Series 3500 PSI, 3.5 GPM with Honda GX390
The Mi-T-M JP Series JP-3504-3MHB is the highest-output model in the JP direct-drive line, producing 3,500 PSI at 3.5 GPM — 12,250 cleaning units — powered by a 389cc Honda GX390 OHV engine and an AR crankshaft pump. At 36% more cleaning units than the JP-3003 (9,000 CU), the JP-3504 handles sustained heavy equipment washing, concrete stripping, and fleet cleaning where lower-output models work too slowly. The Honda GX390 is Honda's commercial heavy-duty single-cylinder, used in compactors, concrete saws, and high-flow pumps.
JP-3504-3MHB High-Output Configuration
The 3.5 GPM flow rate combined with 3,500 PSI is the critical specification for operators who prioritize throughput — more GPM means more water volume rinsing the surface per pass, which accelerates cleaning on large surface areas more than additional PSI alone.
- 3,500 PSI at 3.5 GPM (12,250 CU) — handles fleet washing, concrete stripping, and heavy agricultural equipment at commercial throughput
- 389cc Honda GX390 OHV engine — Honda's commercial heavy-duty single-cylinder with 11.7 ft-lbs torque; adequate for sustained 3.5 GPM pump operation without load drop
- AR crankshaft pump — triplex ceramic plunger pump; rated for high sustained flow rates and extended daily use
- 48-inch lance — longer reach than 36-inch for working at distance on tall equipment and vehicle sides
- 50-foot non-marking hose — covers full vehicle wash bays and equipment rows from one position
- 10-inch flat-free tires, powder-coated steel frame — 142 lbs; two-person loading onto trailers
JP-3504-3MHB Applications and Environments
Fleet maintenance operations washing Class 6–8 trucks and trailers find the 12,250 CU output reduces wash time meaningfully versus 9,000 CU machines. Concrete contractors stripping cured form oil and mineral bond from foundation walls use the 3,500 PSI to cut through residue that 3,000 PSI units work too slowly on. Agricultural cooperatives washing large grain combines and field equipment benefit from the 3.5 GPM flow rate moving mud and crop residue efficiently. County road departments and utility maintenance fleets running regular equipment wash stations find the Honda GX390 straightforward to service in-house.
