CA-3504-1MAH Gas Pressure Washer — CA Aluminum Series 3500 PSI with Honda GX390

The CA-3504-1MAH produces 3500 PSI at 3.5 GPM — 12,250 cleaning units — from a 389cc Honda GX390 OHV engine paired with an AR crankshaft pump on Mi-T-M's aluminum frame. At 125 lbs it is substantially lighter than equivalent steel-frame units at this output level, which typically weigh 140–160 lbs. The step from the CA-3003 series (9,000 CU) to the CA-3504 (12,250 CU) is a 36% increase in cleaning power — the difference between washing moderately fouled equipment surfaces and removing heavy mud, caked road film, and grease from the same surfaces in the same time. ETL listed for US commercial use.

CA-3504-1MAH Output and Engine Selection

The CA-3504 frame is offered in three standard engine variants — Honda GX390 (1MAH), Kohler CH440 (1MAK), and Mi-T-M OHV (1MAM) — all producing the same 3500 PSI / 3.5 GPM from the same 125-lb aluminum frame. The Honda GX390 is the choice for buyers with Honda dealer relationships or who operate in regions with strong Honda service network coverage. A separate 4.0 GPM high-flow variant (1MGH) is also available on the CA-3504 frame with a different pump.

  • 3500 PSI at 3.5 GPM (12,250 CU) — 36% more cleaning power than the CA-3003; handles heavy equipment fouling and road film in fewer passes
  • 389cc Honda GX390 OHV engine — Honda's commercial-duty single-cylinder; global dealer network for parts and service
  • AR crankshaft pump, forged brass manifold, thermal relief valve — AR rated for sustained commercial-duty 3500 PSI; brass handles mineral-rich water; thermal valve protects pump during trigger-closed idle
  • 125-lb corrosion-resistant aluminum frame, vibration isolation plate — 15–35 lbs lighter than steel-frame equivalents; aluminum resists rust in outdoor storage
  • 13-in flat-free tires, ETL listed — larger than the 10-in tires on lower-output CA models; flat-free tires handle rough terrain; ETL listing accepted for commercial procurement
  • 50-ft × 3/8-in hose, 48-in lance — 48-in lance extends reach for elevated surfaces and large equipment; CX-0098 External Bypass available to protect pump from heat build-up

CA-3504-1MAH Applications and Environments

Fleet operators upgrading from the CA-3003 use the CA-3504-1MAH where 9,000 CU is insufficient for their heaviest cleaning loads — tanker truck washing, agricultural equipment with caked mud and silage, and concrete form cleaning. Construction contractors apply the 12,250 CU output to equipment preparation between job sites. Property restoration companies use it for building facade cleaning before coating. Industrial facilities apply it to production equipment washdown involving process residues that lighter units cannot clear in one pass. Municipal vehicle yards use it for heavy fleet cleaning where throughput per shift matters.

Frequently Asked Questions

How much more cleaning power does the CA-3504-1MAH have compared to the CA-3003?
The CA-3504-1MAH produces 3500 × 3.5 = 12,250 CU. The CA-3003 produces 3000 × 3.0 = 9,000 CU. That is a 36% increase in cleaning units — enough to handle heavy mud, caked road film, and industrial residue that requires multiple passes from the CA-3003.
What are the three engine options on the CA-3504 frame?
The CA-3504 standard configuration is available with: Honda GX390 (CA-3504-1MAH), Kohler CH440 (CA-3504-1MAK), and Mi-T-M OHV (CA-3504-1MAM). All produce 3500 PSI / 3.5 GPM (12,250 CU) from the same 125-lb aluminum frame. A separate high-flow variant (CA-3504-1MGH) with 4.0 GPM and a General pump is also available.
Why does the CA-3504 use 13-in tires instead of the 10-in tires on lower-output CA models?
The larger 13-in flat-free tires provide more ground clearance and rolling stability when moving a heavier unit (125 lbs vs. 73–105 lbs for lower CA models) across rough job-site terrain. The increased diameter also reduces rolling resistance on gravel and uneven surfaces.
What bypass accessory is recommended for the CA-3504-1MAH?
Mi-T-M offers the CX-0098 External Bypass System for the CA-3504 frame (distinct from CX-0097 used on CA-2403/2703 and CX-0099 used on CA-3003). The CX-0098 must be ordered with the unit and allows increased water flow through the AR pump during trigger-closed idle periods, preventing heat build-up and protecting pump seals.
Can the CA-3504-1MAH be sold in California?
No. The Honda GX390 on the CA-3504-1MAH is a 49-state engine that does not meet California CARB small engine emissions standards. It cannot be sold or registered in California.
How does the CA-3504-1MAH weight compare to a steel-frame unit at the same output?
The CA-3504-1MAH weighs 125 lbs. Comparable steel-frame pressure washers at 3500 PSI / 3.5 GPM typically weigh 140–160 lbs. The aluminum frame saves 15–35 lbs. For contractors who load and unload multiple times daily, this reduction matters particularly for solo operators without lift assistance.
