The CA-4004-1MAV produces 4000 PSI at 3.5 GPM — 14,000 cleaning units — from a 408cc Briggs and Stratton Vanguard OHV engine paired with an AR crankshaft pump on Mi-T-M's 125-lb aluminum frame. It is one of four engine variants on the CA-4004 standard frame alongside Honda GX390 (1MAH), Kohler CH440 (1MAK), and Mi-T-M OHV (1MAM). The Vanguard is the choice for operations already running Briggs and Stratton Vanguard engines in generators, turf equipment, or other commercial machinery — consolidating parts and service across a Vanguard-engine fleet.
The 408cc Vanguard OHV uses a cast-iron cylinder sleeve, overhead valve configuration, and pressure-lubricated main bearings — construction features consistent with Vanguard's commercial-duty engine line. At 14,000 CU the CA-4004 handles dense industrial fouling, coating stripping, and large-fleet washing that the CA-3504 (12,250 CU) addresses less efficiently. The 125-lb aluminum frame is approximately 17 lbs lighter than the steel-frame JP-4004 at the same CU output.
Facilities and contractors operating Vanguard-powered generators, line stripers, or commercial turf equipment add the CA-4004-1MAV to unify their engine platform: one parts supplier, one oil specification, and shared technician knowledge across all Vanguard-powered equipment. Industrial cleaning operations use the 14,000 CU output for machinery with accumulated heavy fouling from oils, cutting fluids, and process residues. Fleet operators washing heavy commercial vehicles benefit from the 4000 PSI effectiveness on dense road contamination. The aluminum frame keeps the unit at 125 lbs — manageable for solo operators moving between cleaning stations at large facilities.
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.
