Mi-T-M CA-4004-1MGH Aluminum Gasoline Pressure Washer – 4000 PSI, 4.0 GPM, 125 lbs
Mi-T-M CA-4004-1MGH — Aluminum-Frame Direct Drive at 4000 PSI, 4.0 GPM
The CA-4004-1MGH puts 4,000 PSI and 4.0 GPM through a General pump driven directly by a 389cc Honda GX390 OHV engine. The aluminum frame cuts 30–40 lbs. versus steel-chassis competitors at the same output class, while the patented vibration isolation plate keeps pumps and fasteners tight through full-shift operation.
CA-4004-1MGH Engine, Pump, and Frame System
- 389cc Honda GX390 OHV engine — industrial-grade cast-iron bore, 270-hour oil-change interval, electric or recoil start.
- General pump with Mi-T-M Pressure Relief Start — pressure drops to near-zero before the starter engages, eliminating kickback and reducing pull cord wear.
- External bypass system and thermal relief valve — recirculates water when trigger is released, preventing heat buildup that destroys pump seals.
- Forged brass manifold and clear-sleeve water filter — corrosion-proof manifold handles 4,000 PSI continuous; filter is inspectable without tools.
- Corrosion-resistant aluminum frame with patented vibration isolation plate — 125-lb unit rolls on 13-inch flat-free tires across gravel, asphalt, and mud.
Commercial and Industrial Cleaning Applications
Cleaning contractors use the CA-4004-1MGH on concrete, masonry, and painted metal where 4,000 PSI cuts through years of oil, carbon, and biological buildup in a single pass. Fleet maintenance operations rely on the Honda GX390's proven service interval to run the unit across an eight-vehicle wash cycle without mid-job maintenance stops. Construction cleanup crews favor the aluminum frame's weight advantage when loading and unloading from work trucks multiple times a day. Agricultural operations wash harvested equipment and livestock facilities where the 4.0 GPM flow rate reduces total water time per structure. ETL certified for the US market; 49-state engine — not for sale in California without CARB-compliant substitution, consult factory.
