+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. ETL listed for US commercial use.
CA-3504-1MGH High-Flow Output and General Pump
- 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
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.
