Mi-T-M CBA-4004-1MCK Aluminum Series Belt Drive Pressure Washer
The Mi-T-M CBA-4004-1MCK is a gasoline belt-drive pressure washer rated at 4,000 PSI and 3.7 GPM, powered by a 429cc Kohler CH440 OHV engine paired with a CAT triplex pump. The aluminum frame with patented vibration isolation plate reduces operator fatigue and protects components from shock loads. An external bypass system and thermal relief valve protect the pump from heat buildup during extended operation. Weight: 156 lbs. 49-state compliant; not for sale in California.

Industrial Cleaning Applications for the CBA Series
The 4,000 PSI / 3.7 GPM rating (14,800 Cleaning Units) is sufficient for fleet washing, concrete surface prep, graffiti removal, and construction equipment washdown. Belt-drive transmission lowers pump RPM relative to engine speed, extending pump life over direct-drive configurations under continuous-duty commercial use. The two-piece belt guard allows service access without full disassembly.
Frame Construction and ETL Certification
The corrosion-resistant aluminum frame is significantly lighter than steel-frame CWC models while maintaining structural rigidity. ETL certified for the US market. Optional CX-0118 skid feet available for stationary installations (must be ordered with unit). Dimensions: 47" × 27.5" × 28.5".
