Power Pressure Washers

Power Pressure washers, also known as the water jet cleaner are categorized as heavy duty cleaning machines, either used by households or commercially. They are capable of getting rid of stubborn grime, grease and dirt from all kinds of surfaces in record time. Compared to your garden hose, these machines give about 25-100% more pressure power and use 80% less water. The commercial pressure washer is a more potent machine than the household models as they are used to remove extremely stubborn grease and stains, and also used more frequently over long periods at a time. They are also more rugged and robust as they are used in various types of terrains and environments.

They are commonly used in many heavy industry settings like office buildings, automotive manufacturing, food processing plants, agricultural plants, farming equipment and even oil rigs. They are a great help to property management services as they constantly generate millions of dollars in cost savings, achieving the best cleaning results with less manpower.

PSI and GPM of Commercial Pressure Washer
Commercial pressure washers are powered in a variety of ways, namely by electricity, hydraulics, diesel and gasoline and are available with hot water or cold water versions. While there are indeed many types in the market, they are essentially categorized in terms of PSI and GPM. PSI defines the pressure power of water, is measured as pounds per square inch and the higher the PSI, the more powerful the water pressure. The range usually starts from 1,000 PSI to 4,000 PSI and beyond. For commercial machines, most machines are at least 3,000 PSI and above. GPM is defined as gallons per minute of water flow rate and ranges from 2 to 11 GPM with commercial machines starting at 5 and above. The voltage ranges from 115, to 575.

Commercial Pressure Washer Product Pricing And Features
The price for a commercial pressure washer could range from US$4,000 to above US$40,000 depending on the PSI, GPM as well as value added functions. Those which are at the forefront of advanced technologies and are targeted at the high end spectrum commands the extreme high end of the price range. That said, the basic commercial pressure washers comes in difference versions like direct drive, belt driven, trailer, skid mounted.

They are also available with additional cleaning accessories such as wash brushes, extension wands, detergent dispensers, foam applicators, wet sand blast kits, spray guns, chemical injectors, soap screens etc. In addition, the commercial pressure washer comes with much more extensive warranties covering between three to five years of parts and services.

That said, you could greatly cut your household power consumption when using the right equipment for the right home cleaning tasks as well.

All You Need To Know About PSI, GPM AND CU
PSI is technically known as pounds per square inch and most often used to refer to the amount of cleaning pressure the particular machine is capable of delivering. In layperson terms, this means pressure power and the higher the PSI, the greater the consumption of power, translating into relative utilities consumption. Most manufacturers mark their machine models with a tag of a certain amount of PSI to allow buyers to know the pressure power of the machines. This facilitates your search for the right pressure washer by easily referring to the PSI.

GPM on the other hand refers to the gallons per minute and literally means the actual flow of water or the rate at which the unit sprays water. The layperson would term this as water usage. The higher the GPM the greater and consumption of water required. GPM is sometimes included with the model number description together with the PSI.

CU essentially means cleaning units and is referred to the formula of PSI x GPM. This has become increasingly popular in recent years and gives a better perspective on the total pressure power and energy consumption as reference.

The critical aspect of all these acronyms is balance, as you need to strike a balance between PSI pressure power or GPM water usage. To this end, matching your cleaning tasks with the right machines would give you the optimal consumption. It is not always true that having a powerful pressure washer would clean well. You need to bear in mind that too strong a PSI and GPM would cause water damage to the surfaces being cleaned.
