Mi-T-M CBA-3504-1MAH — Belt-Drive 3500 PSI with Honda GX390 and AR Pump

The CBA-3504-1MAH couples a 389cc Honda GX390 OHV engine to an AR pump via a belt drive — a transmission method that runs the pump 30–40% slower than engine RPM, reducing pump heat and extending seal life versus direct-drive configurations. The aluminum frame keeps the unit at 165 lbs., and the patented vibration isolation plate absorbs drivetrain harmonics across full-shift operation.

CBA-3504-1MAH Belt Drive System and Pump Features

  • Belt-drive transmission — decouples pump from engine RPM, running pump at lower speed to reduce heat, noise, and wear versus direct-drive at equivalent pressure.
  • 389cc Honda GX390 OHV engine — commercial-duty cast-iron bore; Pressure Relief Start prevents kickback on 3,500 PSI systems.
  • AR pump with forged brass manifold — AR (Annovi Reverberi) is an Italian pump brand used across commercial and industrial cleaning equipment globally.
  • Thermal relief valve and clear-sleeve water filter — thermal relief discharges heat before pump seal damage; filter inspects without tools.
  • 13-inch flat-free tires and corrosion-resistant aluminum frame — 165-lb unit moves easily on job sites without puncture risk.

Job Site Use Cases for Belt-Drive Pressure Washers

Belt-drive pressure washers are preferred for extended-duration cleaning where pump longevity matters more than upfront cost. Painting contractors running 6–8 hour preparation cycles favor belt-drive units because pump seals last two to three times longer at lower RPM. Industrial maintenance teams cleaning large equipment fleets use belt-drive machines because lower operating temperature reduces glycol and detergent breakdown in the water stream. Fleet wash operations with 100+ units per shift get more service-life-per-dollar from belt-drive configurations than from direct-drive alternatives. ETL certified; 49-state engine — not for sale in California without factory CARB-compliant substitution.

Frequently Asked Questions

What is the difference between a belt-drive and a direct-drive pressure washer?
A belt-drive couples the engine to the pump through a belt and pulley, running the pump at 30–40% of engine RPM. Lower pump speed means less heat, reduced vibration, and longer pump seal life. Direct-drive attaches the pump directly to the engine shaft, running at full engine RPM — simpler but generates more heat during extended operation.
What PSI and GPM does the CBA-3504-1MAH deliver?
The CBA-3504-1MAH produces 3,500 PSI at 3.7 GPM (gallons per minute), giving it a cleaning units rating of 12,950 — sufficient for heavy commercial and light industrial surface preparation and cleaning.
What engine and pump does the CBA-3504-1MAH use?
The engine is a 389cc Honda GX390 OHV with a cast-iron bore sleeve. The pump is an AR (Annovi Reverberi) triplex pump paired with a forged brass manifold and Mi-T-M adjustable-pressure unloader.
Is the CBA-3504-1MAH available for sale in California?
No. The Honda GX390 in this configuration is a 49-state engine that does not meet California's CARB emissions requirements. Contact the factory for a CARB-compliant alternative before purchasing for California use.
What does the Mi-T-M Pressure Relief Start do?
Pressure Relief Start reduces system pressure to near-zero before the starter engages, so the engine pulls over freely without fighting a pressurized pump. This is particularly important on belt-drive units where the pump engages immediately at engine start.
What accessories are included with the CBA-3504-1MAH?
Includes four quick-connect nozzles (0°, 15°, 25°, 40°), a 50-ft non-marking hose, a 48-inch lance, and an insulated trigger gun. Optional CX-0082 external bypass system is available but must be ordered at time of purchase and cannot be added later.
Does the CBA-3504-1MAH have pump overheating protection?
Yes. The AR pump includes a thermal relief valve that automatically discharges water when pump temperature exceeds safe operating limits, preventing seal and packing damage during extended unloaded operation.
