Skid-mounted cold 8 GPM 3500 psi pressure washer S/VB8035HGEA094TF w/ K7.3 flow sensitive unloader mounted remotely on an unloader block.
18" width x 32" long approximately.
The only difference between this unit and the S/VB8035HGEA406 is the K7.3 flow-sensitive unloader mounted remotely on an unloader block in the pressure washer frame instead of on the pump manifold using high-pressure hoses.
Pressure Pro skid mounted cold pressure washer (also available, but not recommended) in a portable unit.
8 GPM 3500 psi Honda GX690 24 HP General Pump TSF2021 v-belt special powder coated steel frame, commercial top of the line flow sensitive ZK7.3 flow sensitive unloader remotely mounted on an unloader block to reduce stress on the manifold, gun/wand assembly with brass general pump quick connects, 50' grey high-pressure hose with quick connects, 5 quick connect nozzles, 20% high draw chemical injector assembly with brass quick connects.
Why choose this model? If you are tired of the pressure-trapped unloaders damaging everything under pressure when the trigger is released, this high-flow 8 GPM pressure washer is your choice. Pressure-trapped unloaders are notorious for leaving ping marks where the balls from the couplers meet on plug collars. The grooves result in damage to the O-rings inside the couplers. High-pressure hoses and high-pressure guns will last longer when using the flow-sensitive K7.3 unloader. You will stop fighting the stiff high-pressure hose when you switch to this unloader. Your body will stop taking the abuse. If you suffer from shoulder pain and tendonitis, this may be your ticket!
Regarding K7 or flow-actuated unloaders: the normal operating rpm on most Honda engines is between 2000-3900. If you run them lower than 2000 for extended periods of time, the combustion chamber will carbon up with unburned fuel and foul the spark plugs (per Honda). The K7 needs full throttle. If you plan to run long distances of hose, choose the #2 orifice or part number 4262.
This powerful, time-saving skid unit will arrive with a 1" hose barb on the inlet of the pump. We strongly recommend that you purchase our pl-8-to or pl-8-ta kit for a tote or a horizontal leg tank which has everything you need to correctly plumb this unit. We recommend switching out the 1" barb to 1.5", upsizing the non-collapsible suction hose to 1.5" ID, upsizing the filter to 80 mesh 1.5", and installing a 1.5"bulkhead, brass hose barb, and 1/2" bulkhead. Increase the jump hose to the reel to a 1/2" high-pressure hose and use a 50' hose as the first length of hose on the reel. (Always strip all hose from the reel except the last single wrap to protect the crimp when in use.) Upsizing the hose ids will allow you to shoot farther, increase the cleaning units and efficiency of your pressure washer as well, and move much faster when using your surface cleaner. The pl-8-to or pl-8-ta kit has everything you need to plumb the pressure washer as well as connect to a reel including the 50' high-pressure hose.
Upsizing your hoses will prevent back-pressure to your pump, help your valves and high-pressure seals last longer, prevent your safety relief valve from spraying water, help your pump run at a cooler temperature, supply enough water to your pump using the 'double your supply hose id in relation to your inlet port' rule and keep your pump cooler leading to less downtime. Double-check your surface cleaner hose to ensure that it is 3/8" id instead of 1/4".
Always use medium thread lock on your high-pressure fittings instead of Teflon tape. Teflon tape will end up in the pump valves or clog nozzles.
If using a chemical injector, install the injector only when in use and install it several feet downstream of the unloader to prevent back-siphoning into the unloader/pump manifold. Did you know you can use dual dual-port chemical injector to apply chemicals at an even stronger ratio? Try the gp100791. It has two barbs.
Connect to a minimum of a 200-gallon water tank or IBC tote.
Add a high-temperature Hudson float valve (Hudson-ht) and Hudson float valve installation kit (Hudson-a) to prevent over-filling your water tank. The Hudson float valve will automatically stop the flow into your tank when installed properly in the headspace of your water supply tank.

We highly recommend adding the best high-pressure 3/8" ball valve (6292.SM) to this order to allow you to turn off the flow of water to switch from the gun to a whisper-wash classic surface cleaner (4345). You will need to ask for two nozzles at 4.5 25 degrees for a two-nozzle spray bar (part 1845) or four nozzles at 2.5 25 degrees for a four-nozzle spray bar (part 1955).
As with any pressure washer, do not adjust the unloader. The unloader is set at a spike pressure of 200 psi above the operating pressure of the pump and is meant to be left alone. If you need less pressure, change out the nozzles to a larger orifice and never smaller than what is called for using factory specifications using GPM and pressure. This unit requires an 8.5 orifice or larger nozzle. You can add a 6540-8 Jrod kit to this pressure washer to experiment with pressure and distance.
This is the most popular pressure washer we offer. The flow-actuated unloader is easier on the body. If you suffer from wrist pain, tendonitis, elbow, back, or neck pain, this unloader will help to alleviate some of the stress that the high gallons per minute and pressure place on your body. You can also add a Suttner relax action gun (4539) or the easy pull gun (4654) to further assist with the relief. The most common feedback we hear regarding the k7 series unloader is that is 'so smooth' and that the person 'will never go back' to the pressure-trapped unloaders.
Pair this unit with a 1/2" All-Flo 17 GPM air diaphragm soft wash system for the most efficient cleaning rig. The 1/2" all-flo can be used to software everything from the roof to a giant commercial building and the 8 GPM pressure washer can be used to rinse using either the new m5ds adjustable nozzle or using a big 0050, 0060, or 2560 nozzle on a gun/wand assembly with low pressure.
