3 Best Dirk Killer Gas Pressure Washers

All Dirt Killer pressure washers have 3 things in common:

  1. Honda GX-LX (2:1 gear reduced) engine 
  2. Kranzle pump
  3. Sold online at

So before getting into the best pressure washers they have to offer let’s look at the benefits of their most important pieces of equipment: engine and pump.

Benefits of Honda GX Commercial-duty Small Engines

Honda GX small engine

We all know and love the Honda brand for small engines, but what exactly makes a GX version commercial quality?

Let’s take a look:

  • Cylinder sleeve. The GX grade Honda’s use cast iron instead of aluminium.
  • OHC/OHV. The GX is OHV design which has both pros and cons when compared to OHC. For one it is more compact allowing more power in a comparatively smaller package and since we are talking about a portable pressure washer – we want high power to weight ratio.
  • Low oil protection. When it senses low oil it will automatically shutoff to protect the engine.
  • Fuel shutoff. You can run all the fuel out of the system to allow easier carb removal and longterm storage.
  • On/off switch. Instead of having the on/off designed into the throttle control the GX has a dedicated switch.
  • Materials used. Plastic vs steel in some areas of the engine including the gas tank.
  • 3-year warranty. All the GX engines have a 3-year warranty from Honda for commercial or private use. The GC model is 2 years private or 90 days commercial.

Benefits of Kranzle Pumps for Pressure Washers

Kranzle industrial wobble pump

The Kranzle pumps used in the Dirt Killer gas pressure washers are industrial-grade with a 10-year warranty. They offer some unique advantages over other common pump brands (CAT, General Pump, AR Blue Clean) used in pressure washers.

Here are some of the benefits they offer:

  • Can run dry or in bypass for hours. Kranzle pumps have stainless steel oversize plungers with ceramic coating only where the stationary pump seals are. This allows it to transfer heat to the oil bath extremely well. Normal pressure washer pumps use all ceramic plungers which do not transfer heat good causing both the water and the pump head to get too hot in bypass.
  • German precision manufacturing. All pumps are manufactured and assembled in Germany under the Kranzle company strict quality control guidelines. This allows Kranzle to use their high-tech CNC machines to ensure every part is 100% matching the design specifications.
  • Corrosion proof. Stainless steel and special brass construction of everything that comes in contact with water inside the pump allows it to be corrosion proof.
  • Stainless steel manometer. To help with any troubleshooting that may come up in the system a pressure gauge is fitted to each pump.
  • Can suck water from tank or pond or even the ocean. Yes, you read that right. You can be on your fishing boat and using the pressure washer out in the bay to clean crab pots sucking water from the ocean. The pumps is self priming with 15-ft of head and since it has only stainless steel and special brass parts internally you can use salt water.

Best Dirt Killer Hot Water Pressure Washer

Dirt Killer Fahrenheit 13 2,700 PSI 5.3 GPM w/ Diesel Heating Coil

Dirt Killer Fahrenheit 13 Hot Water Pressure Washer (1)

We’ve talked about the benefits of hot water for cleaning plenty before but let’s do it again here.

When cleaning anything the two most important factors are soap and hot water. Soap attracts and binds to the dirt and grime and hot water excites all the molecules bouncing everything off the surface and into the stream of water to flow away. Add in high PSI and high GPM and you have the ultimate cleaning machine.

And that’s what we have here: The Fahrenheit 13 hot water pressure washer is the ultimate cleaner. There will be no cleaning task it can’t handle – from restaurant hood cleaning to McDonalds’ dumpsters – all easy work.

It has a Honda GX390 engine and General Pump brand crankshaft pump to give you 5.3 GPM and 2,700 PSI.

The diesel burner raises the input water 125 degrees F (52 degrees C). So if you input room temp water you’ll get out not boiling water but very hot water – much hotter than comes out of any home tap.

With all this cleaning power comes a hefty price tag, but if you own a business that relies on quick cleaning turnaround this will do the quickest and most effective clean.
