+1 (978) 295-7538CA-3504-1MGH Gas Pressure Washer — CA Aluminum Series 3500 PSI, 4.0 GPM High-Flow
The CA-3504-1MGH produces 3500 PSI at 4.0 GPM — 14,000 cleaning units — from a 389cc Honda GX390 OHV engine on Mi-T-M's 125-lb aluminum frame. The 1MGH is the high-flow variant of the CA-3504 frame: where the standard CA-3504-1MAH produces 3.5 GPM with an AR pump (12,250 CU), the 1MGH adds 0.5 GPM with a General pump, increasing cleaning output to 14,000 CU — matching the JP-4004-3MHB output but in a lighter aluminum chassis. ETL listed for US commercial use.
CA-3504-1MGH High-Flow Output and General Pump
The General pump is a commercial-grade crankshaft pump that supports higher flow rates than the standard AR configuration on the CA-3504-1MAH/K/M variants. The 4.0 GPM rating at 3500 PSI means 14,000 CU — the same cleaning output as the CA-4004-1MAH at 4000 PSI / 3.5 GPM, but delivered through higher flow rather than higher pressure. Higher GPM is advantageous for large flat surface areas where flow coverage per pass is more important than concentrated pressure.
- 3500 PSI at 4.0 GPM (14,000 CU) — same cleaning output as the steel-frame JP-4004 but in a 125-lb aluminum chassis; 14% more output than the CA-3504-1MAH at 3.5 GPM
- 389cc Honda GX390 OHV engine — Honda commercial-duty engine; GX390's 389cc displacement supports 4.0 GPM at sustained 3500 PSI load
- General crankshaft pump, integrated external bypass system — General pump rated for sustained high-flow commercial use; external bypass built-in to protect from heat build-up during trigger-closed idle
- 125-lb corrosion-resistant aluminum frame, 13-in flat-free tires — same lightweight chassis as other CA-3504 variants; large tires handle rough terrain
- ETL listed, vibration isolation plate — ETL certification for commercial procurement; vibration dampening extends pump seal life
- 50-ft × 3/8-in hose, 48-in lance — complete kit for large surface and elevated cleaning applications
CA-3504-1MGH Applications and Environments
The CA-3504-1MGH's 4.0 GPM flow rate makes it particularly effective for large flat surface cleaning — parking lots, warehouse floors, aircraft aprons, and large building facades — where high flow covers more surface per pass than high pressure alone. Fleet operators washing large-surface vehicles (box trucks, flatbeds, buses) benefit from the increased rinse rate. Property restoration contractors apply it to wide masonry surfaces before coating. Industrial facilities use it for large-footprint equipment pads where faster rinse cycles reduce downtime. The aluminum frame's 125-lb weight remains manageable for solo operators despite the higher-output pump configuration.
