The Max Flow is our highest-capacity truck skid — 300 gallons of water, two pressure washers, four electric reels, FlowPro remote downstream, and a pure water window cleaning system on one 8 ft platform. Originally built for Alex of Stockton Car Wash (full walkthrough video linked in the photos), it comes everything-installed and ready to spray. Built by hand in Oregon City, Oregon, with a lifetime frame warranty.
This is the skid for operations that outgrew a standard setup: bigger water capacity for bigger jobs, a larger bleach tank for the commercial work, two machines running at once, and window cleaning on the same truck. We recommend a 3/4 to 1 ton truck (an F250/2500 with an 8 ft bed works well). Dry weight is approximately 1,675 lbs.
The Frame
- ✓ Heavy-duty double-reinforced 8 ft aluminum truck skid with lifetime warranty
- ✓ Matching heavy-duty surface cleaner rack designed to hold a Whisper Wash 19" Classic — and a top-of-the-line Whisper Wash 19" Classic is included
- ✓ Every nut, bolt, and washer is rust-resistant stainless — we're moving from 304 to 316 stainless for even better long-term durability
Two Machines, One Skid
- ✓ Honda GX690 custom-built gear drive 8 GPM pressure washer with block-mounted soft release unloader
- ✓ Honda GX390 custom-built gear drive 5.5 GPM pressure washer with block-mounted soft release unloader and electric start
- ✓ Upgraded double-insulated USA-made 6 AWG wiring on the pressure washer; 10 AWG USA wiring, fuse links, and USA fuses on the soft wash system
- ✓ Marine-grade Interstate battery built for daily recharging
300 Gallons of Water Capacity
- ✓ Four extra-thick slim 100-gallon tanks — three plumbed together with heavy-duty plumbing for 300 gallons of water (plumbing the tanks together reduces sloshing), plus a full 100-gallon bleach tank for larger projects
- ✓ Two 7-gallon soap tanks with a 3-way valve to switch between soaps, on our heavy-duty aluminum brackets
- ✓ Hudson float valve assembly and a 1-inch buffer tank drain — drains the tanks, fills buckets, and doubles as an emergency wash station
- ✓ Buffer tank plumbing with crush-proof suction hose, strainer filter system, banjo fittings, and stainless clamps
Four Electric Reels
- ✓ Four upgraded Titan electric full-frame reels rated for chemicals, with stainless manifolds and swivels — two 12-inch reels double stacked and two 18-inch reels double stacked, with our stainless Titan stack kits
- ✓ Heavier-duty USA wiring, USA pure tinned copper lugs, and a USA 50-amp circuit breaker
Soft Wash & Downstream
- ✓ Remco's latest Dual Control 12-volt 7 GPM 100 PSI USA-made soft wash pump with Viton seals — pressure switches dialed in before it leaves the shop, with far less cycling than cheaper pumps
- ✓ Our own Pro Mixer XL with proportional metering valves, 3/4 inch water and bleach valves upgraded free, and top-of-the-line check valves with Hastelloy springs — more chemical resistant than the usual stainless springs
- ✓ Brand new FlowPro electronic downstream system, plumbed properly with a rinse valve system — downstream chemical on the fly
- ✓ 3-way bleach rinse valve with mounts, barbs, and stainless clamps to keep the system fully rinsed
- ✓ ST-510 soft wash gun with stainless couplers, stainless 4-nozzle J-rod dialed to the pump, and a 2315 chemical-resistant house wash gun for downstreaming
- ✓ Kuri Tec poly braid hose on all soft wash plumbing — the one place you can't cut corners
Hose & Pure Water
- ✓ 200 ft of Fierce Jet 1/2 inch soft wash hose with crimped 1/2 NPT fittings
- ✓ Top-of-the-line Fierce Jet grey smooth non-marking pressure hose — rated above standard grey hoses
- ✓ Commercial-grade 100 ft 3/4 inch garden hose with our whip line that reduces kinking on the reel
- ✓ Pressure washer gun with 36-inch lance and M5DS twist nozzle for low-pressure spraying and downstreaming
- ✓ High Flow 4-stage pure water window cleaning system with custom mount
- ✓ Water fed hose reel mounted to the top of the EPW box with a locking, removable bracket — includes 100 ft of quality water fed pole hose
