CA-4004-1MCM Gas Pressure Washer — CA Aluminum Series 4000 PSI, 4.0 GPM with Mi-T-M OHV

The CA-4004-1MCM produces 4000 PSI at 4.0 GPM — 16,000 cleaning units — from a 420cc Mi-T-M OHV engine paired with a CAT crankshaft pump on Mi-T-M's 128-lb aluminum frame. It is the Mi-T-M OHV variant of the high-flow CA-4004 configuration; the Honda GX390 variant is the CA-4004-1MCH. The 1MCM suits buyers who prefer the single-brand service advantage of the Mi-T-M OHV engine — with both engine and pump potentially serviceable through Mi-T-M's authorized dealer network — in the highest-output configuration the CA Aluminum Series offers at 16,000 CU.

CA-4004-1MCM High-Flow Configuration and Single-Brand Support

At 16,000 CU the CA-4004-1MCM is the highest-output unit in the CA Aluminum Series. The CAT pump supports the 4.0 GPM flow rate with an integrated external bypass system, protecting the pump from heat build-up during trigger-closed idle without requiring a separately ordered accessory. The 420cc Mi-T-M OHV engine provides the displacement needed to sustain 4.0 GPM at 4000 PSI under continuous commercial operation.

  • 4000 PSI at 4.0 GPM (16,000 CU) — highest CU output in the CA Aluminum Series; 14% more than the CA-4004-1MAM at 3.5 GPM
  • 420cc Mi-T-M OHV engine — Mi-T-M's highest-displacement OHV; engine and pump supported by Mi-T-M dealer network for single-source service
  • CAT crankshaft pump with integrated external bypass — CAT rated for sustained high-flow commercial use; external bypass included as standard equipment
  • 128-lb corrosion-resistant aluminum frame, 13-in flat-free tires — 3 lbs more than AR pump variants; lighter than steel-frame alternatives at this CU level
  • Vibration isolation plate, 50-ft hose, 48-in lance — vibration dampening extends pump seal life; 48-in lance handles elevated and large-equipment surfaces
  • Integrated external bypass — no separate accessory needed — protects CAT pump from heat at sustained 4000 PSI; standard on all 1MCM configurations

CA-4004-1MCM Applications and Environments

Mi-T-M fleet operators who want unified service for both engine and pump at the highest available portable output choose the CA-4004-1MCM. Industrial cleaning operations use the 16,000 CU output for large-footprint equipment pads, production floors, and machinery with accumulated heavy contamination from oils, process chemicals, and particulates. Fleet operations washing high-surface-area vehicles use the 4.0 GPM flow rate to reduce per-vehicle wash time compared to 3.5 GPM configurations. Construction companies apply it to large concrete form arrays and equipment staging areas. Property restoration firms use it for wide masonry cleaning before recoating on commercial building projects.

Frequently Asked Questions

How does the CA-4004-1MCM differ from the CA-4004-1MCH?
Both produce 4000 PSI / 4.0 GPM (16,000 CU) from the same 128-lb aluminum frame with an integrated CAT pump external bypass. The 1MCM uses a 420cc Mi-T-M OHV engine; the 1MCH uses a 389cc Honda GX390. Choose 1MCM for Mi-T-M unified engine and pump service; choose 1MCH for Honda engine service network. The 1MCH also carries ETL listing; the 1MCM's ETL status is not specified in the product data.
What is the cleaning unit output of the CA-4004-1MCM?
The CA-4004-1MCM produces 4000 × 4.0 = 16,000 cleaning units — the highest output in the CA Aluminum Series. This is 14% more than the CA-4004-1MAM (14,000 CU) and 78% more than the CA-3003-1MAM (9,000 CU), reflecting the combined effect of higher PSI and higher GPM.
Is an external bypass system included with the CA-4004-1MCM?
Yes. Unlike the CA-4004-1MAM where the CX-0098 External Bypass is an optional accessory ordered separately, the CA-4004-1MCM includes an integrated external bypass as a standard feature of the CAT pump configuration. No separate accessory order is required.
Can the CA-4004-1MCM be sold in California?
No. The 420cc Mi-T-M OHV is a 49-state engine that does not comply with California CARB small engine emissions standards. The CA-4004-1MCM cannot be sold or registered in California.
Why does the CA-4004-1MCM weigh 128 lbs versus 125 lbs for the CA-4004-1MAM?
The 3-lb difference reflects the additional mass of the CAT pump versus the AR pump. Both use the same aluminum frame and Mi-T-M OHV engine family. At 128 lbs, the 1MCM produces 16,000 CU — more than the steel-frame JP-4004 (14,000 CU) at 142 lbs, representing a better output-to-weight ratio.
What is the advantage of 4.0 GPM at 4000 PSI versus 3.5 GPM at 4000 PSI for the CA-4004?
At identical 4000 PSI, the surface cleaning force per point is the same. The 4.0 GPM configuration (CA-4004-1MCM) covers approximately 14% more surface area per unit time than the 3.5 GPM configuration (CA-4004-1MAM). For large flat surfaces — warehouse floors, parking decks, vehicle fleets — the higher flow rate reduces total cleaning time meaningfully.
