+1 (978) 295-7538CA-4004-1MAH Gas Pressure Washer — CA Aluminum Series 4000 PSI with Honda GX390
The CA-4004-1MAH produces 4000 PSI at 3.5 GPM — 14,000 cleaning units — from a 389cc Honda GX390 OHV engine paired with an AR crankshaft pump on Mi-T-M's 125-lb aluminum frame. ETL listed for US commercial use.
CA-4004-1MAH Maximum Output and Weight Comparison
- 4000 PSI at 3.5 GPM (14,000 CU) — highest standard cleaning output in the CA Aluminum Series; handles coating stripping and dense industrial fouling
- 389cc Honda GX390 OHV engine — Honda commercial engine for sustained 4000 PSI operation; global service network
- AR crankshaft pump, forged brass manifold, thermal relief valve — AR rated for sustained high-pressure commercial use; brass handles mineral deposits; thermal valve protects pump seals
- ETL listed, vibration isolation plate — ETL certification accepted for commercial procurement; vibration dampening extends pump seal life
- 50-ft × 3/8-in hose, 48-in lance, CX-0098 External Bypass available — complete cleaning kit; bypass must be ordered with unit
CA-4004-1MAH Applications and Environments
Paint preparation contractors use the 4000 PSI to strip loose and failing coatings from masonry and concrete before resurfacing. Municipal and transit fleet operations use it for high-throughput vehicle washing where output per shift is constrained by equipment capacity. Construction firms apply it to heavy equipment cleaning and concrete form stripping. The aluminum frame's portability keeps it viable for solo mobile operations despite the high output level.
CA-4004-1MAH 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.
