+1 (978) 295-7538CA-4004-1MAK Gas Pressure Washer — CA Aluminum Series 4000 PSI with Kohler CH440
The CA-4004-1MAK produces 4000 PSI at 3.5 GPM — 14,000 cleaning units — from a 429cc Kohler CH440 OHV engine paired with an AR crankshaft pump on Mi-T-M's 125-lb aluminum frame.
CA-4004-1MAK Engine Selection and Output
Its cast-iron cylinder liner and full-pressure lubrication system are the same construction features used in Kohler commercial engines rated for high-hour industrial applications.
- 4000 PSI at 3.5 GPM (14,000 CU) — maximum standard output in the CA Aluminum Series; handles coating stripping, dense industrial fouling, and large-fleet washing
- AR crankshaft pump, forged brass manifold, thermal relief valve — AR rated for sustained commercial 4000 PSI; brass resists mineral scaling; thermal valve protects during idle
- 50-ft × 3/8-in hose, 48-in lance, CX-0098 External Bypass available — complete kit; bypass ordered separately and installed at point of sale
CA-4004-1MAK Applications and Environments
Operations with Kohler-powered floor sweepers, compressors, or aerial work platforms add the CA-4004-1MAK to unify their engine inventory: one parts supplier, one oil specification, one service technician across equipment categories. Fleet operations washing tanker trucks, buses, and heavy-duty trailers rely on the 4000 PSI output for efficient removal of road salt, diesel exhaust deposits, and oil contamination. Construction firms apply it to concrete surface preparation and equipment cleaning before redeployment.
CA-4004-1MAK GPM, PSI, and Nozzle Configuration
Rated at 3.5 GPM at 4000 PSI (14,000 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. Cold water only. 49-state engine — not for sale in California.
