When it comes to cleaning, it seems as if you’re forced to choose between working quickly and getting the job done right. The faster you move, the lower standards you’re able to achieve. That’s not the case with pressure washing, though. You can enjoy the best of both worlds.
These machines apply a powerful jet of water to blast away any surface contaminants, be it grease, oil, dirt, algae, and everything in between. They save you time and manual effort without compromising on results.
But not all pressure washers are created equal. Understanding pressure washer PSI is the first step in picking the perfect pressure washing equipment for your specific needs. This speaks to how strong the water jet is.
So how many PSI is an industrial pressure washer? What PSI pressure washer for home use makes sense? You’ve come to the right place. We’ll help you narrow down the optimal PSI rating for any use case below and cover additional details in choosing the right solution.
After all, Jennychem is your trusted choice for a Kranzle pressure washer, the UK’s #1 brand in residential and industrial pressure washing. Shop models ranging from 1,500 PSI to well over 4,000 PSI today!
What is Pressure Washer PSI?
First things first - what exactly is pressure washer PSI? It stands for pounds for square inch, which is why you might not be too familiar with this rating here in the UK. Our machines are typically rated in bar, not PSI. This doesn’t make PSI any less important, though.
A higher PSI means greater cleaning power for tackling tougher messes, stripping paint, or blasting away built-up dirt on concrete and industrial surfaces. Sometimes, though, less is more. Too much PSI can cause damage to a surface.
Now, as you go forth shopping for a pressure washer here in the UK it’s important to note you’ll probably see units rated in bar instead. One bar is equivalent to roughly 14.5 PSI. So, a 100-bar pressure washer is basically a 1,450 PSI pressure washer.
We use bar simply because it aligns with the European engineering standards and reflects real-world performance more accurately. However, you should be able to make sense of both ratings since there’s no telling what you’ll encounter here in the UK market.
We also want to make it clear that PSI, or bar, is just one way to assess pressure washer performance. You’ll need to take it into account with other criteria as well to choose the optimal pressure washing solution. For now, though, how many PSI is an industrial pressure washer?
How Many PSI is an Industrial Pressure Washer?
Just about any UK business can benefit from investing in pressure washing, be it for keeping up appearances for customers or staying compliant with health code regulations. These are as strong as pressure washers get since they face such tough messes.
PSI Ranges for Industrial Applications
- 2,500 - 3,500 PSI (170 - 240 bar): Ideal for commercial cleaning, fleet washing, and agricultural use. They remove dirt, mud, and light oil stains from vehicles, machinery, and industrial floors.
- 4,000 - 5,000 PSI (275 - 345 bar): Used in construction and manufacturing for stripping paint, cleaning heavily soiled equipment, and washing down large warehouses or shipping yards.
- 5,000 - 7,000+ PSI (345+ bar): Designed for extreme applications like graffiti removal, concrete surface preparation, and marine cleaning. Pressure washing becomes almost abrasive at this level removing tough coatings and contaminants with ease.
Use Cases for Industrial Pressure Washers
There are a seemingly endless number of applications for an industrial pressure washer. After all, time is money in your business, and you need a machine that helps you maintain peak productivity without sacrificing results. Here are some of most common use cases:
- Construction Sites: Removing hardened mud, cement residue, and debris from heavy machinery and scaffolding.
- Manufacturing Plants: Cleaning grease, oil spills, and industrial residues from floors, conveyors, and production equipment.
- Fleet Maintenance: Eradicating dirt and grime from commercial vehicles, lorries, and farm equipment to prevent long-term wear and corrosion.
- Warehouse and Commercial Facilities: Keeping floors, loading docks, and storage areas clean and free from slip hazards.
- Marine and Shipyards: Stripping algae, barnacles, and salt buildup from boats and docked vessels.
- Concrete and Surface Restoration: Preparing surfaces for resealing by removing old coatings, stains, and buildup.
Just be aware, industrial pressure washers should not be used for residential settings. They’re too powerful and will almost always cause more harm than good. In these more sensitive settings, you need a residential pressure washer.
What PSI Pressure Washer is Best for Home Use?
That being said, what PSI pressure washer is best for home use? Just as with industrial pressure washer PSI, there’s no one-size-fits-all answer. It all depends on the surface you’re cleaning and the messes you’re trying to eliminate.
PSI Recommendations for Different Household Cleaning Jobs
- 1,300 - 1,800 PSI (90 - 125 bar): Ideal for light-duty tasks like washing cars, bikes, garden furniture, and outdoor grilles. Safe for delicate surfaces like wood decking.
- 1,800 - 2,500 PSI (125 - 170 bar): Great for cleaning patios, driveways, brickwork, and siding. It’s strong enough to remove mildew, mud, and light stains without stripping surfaces - the ultimate sweet spot.
- 2,500 - 3,200 PSI (170 - 220 bar): Best for heavy-duty home cleaning, be it removing oil stains from driveways, stripping paint, or cleaning second-story exteriors.
- 3,200+ PSI (220+ bar): These are rarely needed for home use but can handle the toughest jobs, such as deep concrete cleaning or heavy moss and mould removal. This technically falls under the umbrella of industrial PSI, though.
Finding the Right PSI for Your Needs
The tricky part of understanding what is a good PSI for a pressure washer is that you probably have a few different things you want to use it for, and they involve different surface materials and contaminants.
In this case, think about what you intend to clean most often. A machine between 1,500 - 2,000 PSI will be best for general home maintenance, whereas deeper cleaning calls for something as strong as 2,500 PSI.
Ideally, you’d be able to get an adjustable unit with interchangeable nozzles so you can tailor the pressure to the specific task at hand. But whether you’re trying to learn how to clean a patio with a pressure washer or how to get oil stains off driveway, PSI is just one thing to consider.
Pressure Washer PSI is Just One Piece of the Puzzle
PSI dictates cleaning power, but power isn’t everything. Speed matters too, and there’s a different rating for that. How your pressure washer is powered matters as well, so you’ll need to pick between petrol or electric operation. We’ll quickly walk you through all this and more below.
The Role of GPM or L/HR
While PSI determines the force of the water, GPM (gallons per minute) or L/HR (litres per hour) here in the UK speak to how much water is being delivered. This dictates how quickly you can cover a space. Here are some common flow rates for UK pressure washers:
- Low GPM (5-7 L/Min or 300-420 L/HR): Suitable for light-duty home cleaning.
- Medium GPM (8-10 L/Min or 480-600 L/HR): Good for patios, driveways, and brickwork.
- High GPM (10+ L/Min or 600+ L/HR): Used in industrial and heavy-duty applications.
A higher flow rate empowers you to blast away dirt and debris faster, but it’s worth noting that at a certain point more flow is just wasteful. Find the sweet spot for your unique cleaning needs.
Petrol vs Electric Operation
Pressure washers can be powered either by an electrical outlet or petrol, and there are pros and cons to each. Electric pressure washers are lighter, quieter, and easier to maintain. They’re perfect for home use as they typically max out at around 2,500 PSI (170 bar).
For more power and mobility, a petrol pressure washer might make sense. These can easily exceed 2,500 PSI/170 bar and they’re also more portable. However, they cost more, they’re harder to maintain, they’re loud, and they put out emissions. They’re limited to outdoor use.
Mobility for On-the-Go Cleaning
If you have a large area to cover it’s worth investing in a pressure washer that has heavy-duty castors for easy movement around the property. You should also take hose length into account so you don’t have to deal with extensions or feel restricted.
Some industrial pressure washers can even be mounted on a trailer for off-site jobs. With a water tanked attached to the trailer, you have the ultimate remote cleaning arsenal.
Nozzles and Spray Angles
We’ve touched on nozzles a bit throughout this pressure washer PSI guide, but you have a ton of different options at your disposal. Each has its place in your cleaning regimen:
- 0° (Red Nozzle): Extreme pressure for stubborn stains, but risky for delicate surfaces.
- 15° (Yellow Nozzle): Good for removing dirt and paint from hard surfaces.
- 25° (Green Nozzle): All-purpose cleaning for patios, decks, and driveways.
- 40° (White Nozzle): Safe for windows, cars, and soft surfaces.
- Soap Nozzle (Black): Designed for applying detergents efficiently.
You may not need all of these, but you’ll definitely want an assortment on hand so you’re prepared for any cleaning task you encounter.
Enhancing Cleaning With Detergents
Aside from the pressure washer itself, you might want to stock up on detergents to clean smarter instead of harder. The right cleaning chemicals can allow you to tune down the pressure without compromising on results.
Don’t bother with a homemade patio cleaner - we have the best patio cleaner, the best driveway cleaner, and just about any other flat surface cleaner you could need right here at Jennychem.
