Mi-T-M CA-4004-1MAM Aluminum Pressure Washer – 4000 PSI, 3.5 GPM, OHV engine

CA-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. The Mi-T-M OHV variant consolidates engine and pump service under Mi-T-M's authorized dealer network — a single contact for all warranty claims, parts, and scheduled maintenance. Buyers managing fleets of Mi-T-M washers benefit from standardizing on this engine across units at multiple output levels. ETL listed for US commercial use.

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. At 14,000 CU the CA-4004 handles applications where the CA-3504 (12,250 CU) still requires additional passes — dense oil residue on concrete, heavily fouled vehicle undersides, and industrial equipment with process chemical buildup. The 125-lb aluminum frame weighs approximately 17 lbs less than the steel-frame JP-4004 at the same CU output.

• 4000 PSI at 3.5 GPM (14,000 CU) — maximum standard output in the CA Aluminum Series; handles dense fouling and coating stripping that overtaxes the CA-3504
• 420cc Mi-T-M OHV engine — Mi-T-M's highest displacement OHV; engine and AR pump both under Mi-T-M dealer warranty for single-source service
• 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
• 125-lb corrosion-resistant aluminum frame, 13-in flat-free tires — lighter than steel-frame JP-4004 at the same CU output; rust-resistant outdoor storage
• ETL listed, vibration isolation plate — ETL certification for commercial procurement; vibration dampening extends pump seal service intervals
• 50-ft × 3/8-in hose, 48-in lance, CX-0098 External Bypass available — complete kit; bypass must be ordered with unit

CA-4004-1MAM Applications and Environments

Mi-T-M fleet operators who standardize their entire pressure washer inventory on Mi-T-M engines use the CA-4004-1MAM as their highest-output portable unit: parts, oil, and service all flow through the same dealer contact regardless of which unit needs attention. Industrial cleaning contractors apply the 14,000 CU output to production equipment with accumulated process chemical, oil, and particulate fouling. Fleet maintenance operations use it for heavy commercial vehicle washing where 12,250 CU units leave residue on undercarriages and heavily contaminated surfaces. Construction firms use it for concrete surface preparation, equipment cleaning, and form stripping at the highest output the aluminum chassis offers.
