Mi-T-M CBA-4004-1MAH Aluminum Belt Drive Pressure Washer – 4000 PSI, 3.4 GPM, Honda
Mi-T-M CBA-4004-1MAH — Belt-Drive 4000 PSI with Honda GX390 and AR Pump
The CBA-4004-1MAH delivers 4,000 PSI through a belt-driven AR pump powered by a 389cc Honda GX390 OHV engine — stepping up pressure from the 3,500 PSI CBA-3504 range while keeping the same aluminum frame and 165-lb weight. Belt drive runs the pump at reduced RPM for cooler, longer-lasting operation at this higher pressure rating.
CBA-4004-1MAH Engine, AR Pump, and Belt Drive System
- 389cc Honda GX390 OHV engine — commercial cast-iron bore; Pressure Relief Start; Mi-T-M adjustable unloader.
- AR pump at 4,000 PSI / 3.4 GPM — AR triplex pump delivers 13,600 CU cleaning output; forged brass manifold withstands sustained high-pressure cycling.
- Belt-drive transmission — runs pump below engine RPM; generates less heat than direct-drive at equivalent pressure, extending seal life.
- Thermal relief valve and clear-sleeve water filter — heat protection; filter inspectable without tools during mid-shift checks.
- Aluminum frame with vibration isolation plate, 13-inch flat-free tires — lighter than steel-frame 4,000 PSI units; tires handle debris-covered job sites.
Heavy-Duty Cleaning Applications at 4000 PSI
At 4,000 PSI, the CBA-4004-1MAH handles tasks that lower-pressure machines cannot complete in a single pass: industrial graffiti removal from concrete and masonry, removing rubber tire marks from parking structures, stripping peeling paint from metal equipment and steel structures, and cleaning caked-on concrete residue from form work. Construction site cleaning contractors use 4,000 PSI belt-drive machines for daily equipment wash-down where volume of work requires a pump that holds up through multi-hour continuous operation. ETL certified; 49-state — not for California; optional CX-0082 external bypass must be ordered with unit.
