Diesel Pressure Washer FAQ's

What Is a Diesel Pressure Washer?

Pressure washers are part garden hose and part air compressor. A typical pressure washer has either a gas-fueled engine or electrical powered motor that powers a water pump. The pump accelerates the water, supplied from a garden hose, to produce high pressure. The washer is hooked to a high pressure-rated hose. At the end of the hose is a water gun that looks similar to the pressure guns used at car washes. When the trigger is pulled, the water mixes with the air and comes out of the nozzle. Pressure washers can aggressively blast things clean with water jets pressurized at about 75 times the pressure of a garden hose. Or, they can gently spray with lower pressures for delicate cleaning.

Why Choose a Diesel Pressure Washer?

Diesel pressure washers are used to clean hard surfaces across industrial, commercial and construction applications and for homes. Suppose you are unsure which pressure washer is best? In that case, our professional pressure washer sales team is ready to provide expert advice and guidance, ensuring you choose the right pressure washer to meet your needs. Our range includes both petrol and diesel high pressure washers.

Should I Choose a Petrol or Diesel Pressure Washer?

Most petrol pressure washers are on four wheels, making them manoeuvrable and unrestricted by their power source. This means paired with a water tank, they can be used remotely or moved around between cleaning jobs. This does however make them heavier than electric machines because they need to carry around their own fuel, and if used remotely their water supply as well. On the other hand, diesel pressure washers have fuel efficiency as an advantage. Although diesel might be more expensive to purchase it lasts a lot longer than petrol and can be running for hours on end. They also tend to have a higher flow rate and more powerful engines, minimising cleaning times. This means diesel pressure washers are most common for industrial applications.

What Size Diesel Pressure Washer Do I Need?

Determining the size of the pressure washer required takes into consideration several factors. These factors are explained in the points below for your consideration. The pressure put out by a pressure washer is measured in PSI (pounds per square inch). PSI is a critical consideration in the choice of a pressure cleaner because the pressure put out by the pressure cleaner impacts directly on the cleaning performance. The requirements can vary depending on what you are using the pressure cleaner for. 1,000 – 1,900 PSI: This type of pressure is good for the average homeowner to handle most household and vehicle cleaning jobs, anything from a barbeque to a car wash. This range tends to be most common with domestic pressure cleaners. 2,000 – 2,900 PSI: This type of pressure is good for the heavier residential jobs, or commercial cleaning. 3,000 PSI: This is a quite high PSI, and most common in industrial and commercial machines. At this PSI you should be careful of what surfaces you clean. Industrial equipment, concrete and boats are common applications for this PSI. 3,000+ PSI: This PSI is very high. You should be extremely careful with this PSI level as you can easily strip paint or damage surfaces. This PSI level is commonly used for purposes from graffiti or paint stripping, to blasting dried concrete off scaffolding.
