Temporary Price Reduction on our best selling rotating pressure washer nozzle

One of Water Cannons bestselling Rotating Turbo nozzles, is made by MTM Hydro, and rated to 4,000 PSI and 195 degree F.  This nozzle now comes standard with a ¼” QC Plug so it is ready to work right out of the box.  Remember always start any rotating nozzle pointing in the downward position to avoid damage to the nozzle.  This rotating turbo nozzle is rebuild- able out-in-the-field by simply removing the protective rubber cover and then unscrew the large hex nut to replace the old cartridge with the new one.  Repair kits sold separately.

The more powerful pressure washers with pressure levels up to 4000psi can accomplish tasks that most cleaning equipment can't even touch, like stripping paint, degreasing heavy-duty equipment, and removing the most stubborn oil, dirt, grime, and soil residues from concrete, walkways, driveways, sidewalks, brick, building exteriors, and much more. Specially designed accessories can make any pressure cleaning job easier and more efficient. 

For paint stripping or barnacle removal we recommend adding a rotating nozzle to your system. The turbo rotating nozzle increases the blasting power by concentrating a zero degree stream of water into a 25 degree high rpm pattern.   

The exclusive design of the Turbo Nozzle 4000 eliminates start up impact and damage to the internal nozzle. Rotating nozzles are two times as effective as flat nozzles, so you can cut the time it takes to complete a job in half. In fact, you may save even more time, as using a rotating nozzle also eliminates shadowing so there is no need to double back. Lastly, high RPM spraying power in an adjustable 5 to 25 degree circle allows you to focus pressure for stubborn grime. 

• 1/4 quick connect plug installed

• 0° impact, 25° pattern

• Maximum temperature: 210°F

• High strength forged brass 

• No gears, no teeth, no bearings 

• Precision ceramic orifice and matching race

• Durable rubber/plastic cover

The most important part in any high pressure spray machine is the Spray Tip or Nozzle.

 The spray tip consists of 2 parts that make the washer work to produce a high pressure spray.  The size of the hole is the part that actually makes the pressure.  This is typically the 2nd set of numbers in a nozzle part number.  They will come in half sizes like: 2.0, 2.5, 3.0, 3.5, 4.0 etc.     The smaller the hole the higher the pressure.  The larger the hole the lower the pressure.  This is NOT the Gallons per minute of the pump.  The gallons per minute of the pump will vary depending on the model number and RPM of the individual pump.
You can put any number of different gallons per minute through the same size nozzle and you will get different pressures.  Of course with too small of a nozzle you can put too much pressure on your pump  and damage the pump and system.
For example:  2.0 GPM through a #3.0 nozzle=1,750 PSI.
2.5 GPM through a #3.0 nozzle=2,800 PSI.    3.0 GPM through a #3.0 nozzle=4,000 PSI.  
3.5GPM through a #3.0 nozzle=5,500 psi  etc.
This is why we have either a nozzle calculator or a nozzle chart on any of our nozzle pages throughout the web sites.  You must know the Gallons Per Minute(GPM) and Pressure(PSI) of your pump to ensure you get the correct nozzle size for your machine.  Too small, too much pressure, too big, not enough pressure.  
The first set of numbers in a spray tip represent the flat spray pattern that the water comes out of the nozzle at.  For instance: 0 degree is like a lazer point, 15 degree is the next size up for most concentrated spraying with a little coverage area, 25 degree, and 40 degree for the most coverage.  The quick disconnect nozzles are color coded to reflect the spray pattern, not the hole size.  Usually, the spray angle does not affect the pressure.  It may seem like a lower PSI with the wider spray when in fact it is the decreased concentration of area the water is hitting that makes it seem less.
It may seem confusing but if you have the GPM and PSI of your pump, just plug this in to our nozzle calculator and Water Cannon will send you the right one every time.

When the Rotating Nozzle stops working

Water Cannon Duct Cleaners Attach to any Pressure Washer

By Luke LeNoble
Mosmatic Duct Cleaners from Water Cannon are designed to clean ducts, trash chutes, vents, restaurants hoods, tanks and more. The spinner attachment can be universally attached to any hot or cold pressure washer, making it a versatile tool for any cleaning contractor.

“You can connect it to the wand, or you can connect it to your hose,” says Mark Williams, Water Cannon national sales and product manager. “Because of the versatility of what you can clean, you’re not limited to just ducts. A lot of grease trap guys are cleaning restaurants, so now they can offer to clean that hood vent as well.
“You can clean anything where you have to hit the sides of a pipe or wall because you can’t get a wand in there to hit all the spots. This is where a duct cleaner comes in handy; you can drop it through the hole, and then it sprays and rotates at about 1,500 rpm, so it will clean the sides of the wall or whatever you’re cleaning.”

The duct cleaners are made of corrosion-resistant materials, feature self-lubricated steel bearings and an improved carbide swivel. They come in sizes from 3 to 32 inches.

Built to handle chemical ratings of pH 3 to pH 12 while withstanding temperatures up to 250 degrees F, operators can choose between fixed-arm or adjustable-arm models and prevent backsplash with an optional protective plate for sizes 12 inches and up.

“These duct cleaners are really a time-saver and very versatile, cleaning anything from a 3-inch pipe to a silo,” Williams says. “And it’s a high quality product; they’re made to last.” 800/333-9274; 

How to use a pressure washer

The easiest way to learn how to use a power washer is to first understand how the power washing systems work. There are four basic elements of the powerwashing process regardless of what machine or method you use. The four elements and power washer tips are: pressure, water flow rate, cleaning solution and heat. If we take out just one of these four elements, the cleaning characteristics will change. For example, if you can only afford a cold water pressure washer instead of hot water washer, you will have to compensate for that loss. In other words, pressure washer basics tell you that you will have to add more chemicals, apply higher pressure and use more water to achieve better powerwash results. Therefore, you will always have to make adjustments combining these four elements in order to achieve the ideal cleaning atmosphere for your particular job. Nevertheless, when learning how power washing systems work and how to power wash, keep in mind that detergents emulsify the dirt better and faster as the temperature increases. This is especially true when cleaning oil and grease from a concrete surface. That's why hot water power washing systems are perfect for such jobs.

So, how does the high pressure washing work? It is in fact the process of breaking the bond between the dirt and the surface being cleaned. As we mentioned earlier, for the best results you will combine four essential elements. However, shortfalls do exist. Here is another example of how pressure washers work: let's say you notice you have a little detergent left and you decide to decrease the amount injected through pressure washer. A cleaning solution decrease in this case will have a less effect on the debris being cleaned. Because of that, now you must work with other elements to make up for that loss. You have to increase the pressure, water temperature and the water volume. Even though, you are less likely to reach the same level of efficiency (by decreasing the amount of detergent), you will somewhat neutralize that loss.
