The Ultimate Guide to Pressure Washers

How to Choose an Industrial Pressure Washer

When selecting a pressure washer, you first want to make sure that you choose equipment that can stand up to the demands of industrial and commercial cleaning jobs. Industrial power washers are reliable, rugged, and built to last in harsh environments. Compared to residential equipment, industrial units will offer higher pressure, better flow rates, and excellent durability. They also deliver faster cleaning than at-home pressure washers to save you money on operations and labor. 

The best way to choose an industrial or commercial pressure washer is to consider your application’s specifications. Evaluate your application by answering these pressure washer questions:

• How many hours per week do you anticipate using your industrial pressure washer?
• Do you require a portable or stationary pressure washer?
• Does your application have access to a gas line, electricity source, or other power supply?
• What substance do you seek to clear?
• Is hot water necessary, or will cold water suffice?

What are GPM & PSI for Pressure Washers?

Pressure washer capabilities are measured using two primary units: gallons per minute (GPM) and pounds per square inch (PSI). GPM relates to the amount of water that passes through your equipment, and PSI references the pressure intensity at which water leaves your pressure washer. In short, GPM measures how fast the grime can be rinsed away, and PSI measures your pressure washer’s ability to separate dirt or build-up from your surface. Understanding GPM and PSI will help you choose the right pressure washer for your projects.

Does GPM or PSI Matter More for Pressure Washers?

Your application decides if GPM or PSI matters more in your selected pressure washer. When you need to clear a large amount of dirt quickly, GPM is the more important metric. If you are removing caked-on or difficult substances, PSI will be the most significant factor. 

Choosing Hot or Cold Pressure Washers for Industrial Applications

Pressure washers are available in a wide range of configurations to meet any industrial specification. Once you’ve determined the power washing features you need to complete your job, it’s time to find the best model for your purposes. Choosing between a hot or cold pressure washer will depend on many considerations, including the material being washed, the amount of washing anticipated, and the pressure capabilities required.

Hot Water Pressure Washers

Hot water pressure washers effectively cut through oil, grease, gum, and other hard-to-clean substances from industrial surfaces. While hot water pressure washers tend to be more expensive than their cold-water counterparts, their enhanced cleaning abilities make up for the extra cost. They also do not require the use of chemicals to provide comprehensive cleaning. Options include:

• Electric-powered heated pressure washers
• Gas-powered diesel-heated pressure washers
• Diesel-powered heated pressure washers

Cold Water Pressure Washers

Compared to heated pressure washers, cold water pressure washers weigh less, cost less, and deliver high-quality cleaning for most industrial applications. Many models of cold water pressure washers feature the ability to inject detergents to aid in clearing away dirt and other substances. Possible power options and configurations for cold water pressure washers can include:

• Electric-powered pressure washers
• Gas-powered pressure washers
• Diesel-powered pressure washers
• Hydraulic-powered pressure washers

Gas vs. Electric Pressure Washers: What’s the Difference?

Determining whether a gas-powered or electric washer is suitable for your application will depend on many factors. The differences between gas and electric pressure washers include factors such as portability, usage, and industries served. Both gas and electric pressure washers are available in hot and cold water models.

Gas & Diesel-Powered Pressure Washers

Gas-powered pressure washers do not require an external power source, making them highly portable and easy to move. However, they must only be used in outdoor environments to prevent the confinement of hazardous fumes. They have high PSI and GPM capabilities, making them desirable for heavy-duty applications, while fragile materials should be avoided. Industries including construction and the military benefit from gas pressure washers and their strength for tough applications.

Please note: Any pressure washer that uses fuel to operate should only be used outdoors or in well-ventilated areas. Consult your local HVAC expert to ensure your ventilation system is properly installed.

Electric Pressure Washers

Electric pressure washers offer greater location flexibility for pressure washing, as they can be used both indoors and outdoors. However, they require an external power source, decreasing portability. Electric washers are generally smaller and require less maintenance to perform at maximum capacity. They are commonly used in janitorial or agricultural projects for washing applications including decks, sidewalks, and cars, as well as for machinery and pork production facilities.

Accessories for Industrial Pressure Washers

Accessories are additional parts that can enhance your pressure-washing capabilities. From nozzles to hoses to wands, pressure washer accessories can help ensure your machine performs at its best.

Determining the Correct Pressure Washer Nozzle Size

Choosing the right nozzle tip for your pressure washer is essential for proper functionality. If the nozzle is too large or too small for your machine, the pressure may be altered dramatically, becoming too weak for washing or too powerful for fragile surfaces. The machine can become overwhelmed, creating internal pressure buildup and damage. The correct nozzle will ensure your machine is functioning properly throughout all applications.

Use our Nozzle Size Calculator to determine the right nozzle for your pressure washer. Simply enter the GPM and PSI of your machine to find the proper tip for your washer.

Replacing Components on Your Pressure Washer

With extensive use over long periods, individual parts of your pressure washer may need replacing. Replacement pressure washer parts are designed to seamlessly substitute original parts and help your machine continue to function at its best. Find the right replacement parts for your machine from Cam Spray’s extensive inventory.

Custom Industrial Pressure Washers

Not all applications are satisfied with an off-the-shelf pressure washer design. Consider choosing a custom-built pressure washer when you want precise PSI capabilities, an unusual size, or to meet particular portability requirements. You can rest easy knowing that your pressure washer meets every specification needed to complete your job on time, within budget, and without interruption.
