+1 (978) 295-7538CA-4004-1MAM Gas Pressure Washer — CA Aluminum Series 4000 PSI with Mi-T-M OHV Engine
The CA-4004-1MAM produces 4000 PSI at 3.5 GPM — 14,000 cleaning units — from a 420cc Mi-T-M OHV engine paired with an AR crankshaft pump on Mi-T-M's 125-lb aluminum frame. It is one of four engine options on the CA-4004 standard frame. Buyers managing fleets of Mi-T-M washers benefit from standardizing on this engine across units at multiple output levels.
CA-4004-1MAM Single-Source Service and Output
The 420cc Mi-T-M OHV is Mi-T-M's highest-displacement OHV engine, providing the torque needed for sustained 4000 PSI / 3.5 GPM operation at the AR pump.
- AR crankshaft pump, forged brass manifold, thermal relief valve — AR rated for sustained 4000 PSI commercial use; brass handles mineral-rich water; thermal valve prevents heat damage during idle
- 50-ft × 3/8-in hose, 48-in lance, CX-0098 External Bypass available — complete kit; bypass must be ordered with unit
