Whether you are buying pressure washers for residential or commercial environments, it pays to select the right machine. Standard commercial systems offer pressure levels up to 2000 psi. Industrial machines can produce pressure levels beyond 2500 psi or even 3000 psi. Temperature and water flow rates are additional features you need to consider.
Commercial Pressure Washers
Pressure washing machines in this class offer pressure ratings up to 2000 psi. A typical entry-priced machine will offer pressure levels starting at 750 psi and flow rates of nearly 1.4 GPM. These pressure washers are ideal for applications on delicate surfaces susceptible to scratching or gouging from a more powerful pressure washing machine.
More advanced pressure washers will offer higher pressure levels and water flow rates. Some of these pressure washers will carry pressure ratings that top at 1500 psi, while others can attain levels of 2000 psi. A heavy duty model can boast pressures of 2000 psi coupled with water flow rates of 4 GPM.
The Well-Designed Commercial Pressure Washer
A well designed machine in this class of commercial pressure washer systems
will offer three modes of cleaning: hot water, cold water, along with pressurized steam. To achieve these temperatures the machines generally will include a fuel-burning heater system. These pressure washers will generally burn propane or some form of gas. Depending on the machine, the pressure washer system will typically ship with a 30-pound, 40-pound or 50 pound empty tank for propane. Generally, this type of mobile pressure washer equipment will reach fully functional temperatures in approximately 30 seconds.
Industrial Pressure Washers
This type of pressure washing equipment offers the highest levels of performance, pressure and water flow for the most difficult cleaning applications. A typical industrial pressure washer will offer pressure levels starting at 3000 psi and flow rates starting at 5 GPM. As with commercial pressure washers, these industrial machines will generally support three temperature modes of performance.
Industrial pressure washers can be powered either by electricity or gas. The electrically powered pressure washers
generally include 220-240 volt motors, either in 60 Hz or 50 Hz configurations, depending on the country in which you are working. The electrical motors of these industrial pressure washers are often rated for about 10 HP.
More Powerful Best Pressure Washers
Gasoline powered pressure washers
can often offer the highest levels of power, pressure and portability. Typical of these pressure washing machines are systems that will offer upwards of 3500 psi and rely on a gas engine rated for 18 HP.
Always look for industrial pressure washers with electronic direct spark ignition systems for speed and reliability. Another feature to look for: heavy duty heating exchange coils made of schedule 80 materials.
These advanced pressure washing machines are generally sold with 50 foot hoses rated for high pressure. Pump drive methods will range from belt drive to shaft driven. Generally, this type of pressure washing machine offers optional support for multi gun operations.
Regardless of whether you are purchasing a commercial pressure washer or an industrial pressure washing equipment
always check the warrantee. A solid vendor will cover parts and labor worldwide.
