+1 (978) 295-7538CA-4004-1MCH Gas Pressure Washer — CA Aluminum Series 4000 PSI, 4.0 GPM with CAT Pump
The CA-4004-1MCH produces 4000 PSI at 4.0 GPM — 16,000 cleaning units — from a 389cc Honda GX390 OHV engine paired with a CAT crankshaft pump on Mi-T-M's 128-lb aluminum frame. The integrated external bypass system is standard on the CAT pump configuration, providing continuous pump protection without requiring a separately ordered accessory. ETL listed for US commercial use.
CA-4004-1MCH CAT Pump and High-Flow Configuration
CAT pumps are a recognized commercial-duty brand in the pressure washer industry, specified for sustained high-flow applications.
- 389cc Honda GX390 OHV engine — Honda commercial engine providing torque for 4.0 GPM at 4000 PSI sustained load
- CAT crankshaft pump with integrated external bypass — CAT pump rated for sustained high-flow commercial use; external bypass included, not a separate accessory
- ETL listed, vibration isolation plate — ETL certification for commercial procurement; vibration dampening reduces pump seal wear
- 50-ft × 3/8-in hose, 48-in lance — complete cleaning kit for large vehicle and building surfaces
CA-4004-1MCH Applications and Environments
The CA-4004-1MCH's 4.0 GPM flow makes it particularly effective for large flat surface applications: parking lot and airport apron cleaning, warehouse floor washing, and large building facade cleaning where faster area coverage per pass reduces total cleaning time. Fleet operations washing high-surface-area vehicles — buses, tankers, large flatbeds — use the 16,000 CU output to maintain throughput. Property restoration contractors use the 4000 PSI output for coating prep on wide masonry surfaces. The ETL listing makes it acceptable for facility-approval procurement processes where independently certified equipment is required.
CA-4004-1MCH GPM, PSI, and Nozzle Configuration
Rated at 4.0 GPM at 4000 PSI (16,000 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. Integrated external bypass system. Cold water only. 49-state engine — not for sale in California.
