Imagine writing your name in wood with a red zero-degree spray tip. However, the thin stream it produces is too narrow to cover significant surface area. Cleaning a driveway with such a spray tip would be time-consuming. Now, think about the power of that spray tip spinning at super speeds.

That's what a turbo nozzle does. By spinning the water stream, it cleans a broader path, allowing you to clean larger areas quickly with the highly concentrated zero-degree stream.

How Does a Turbo Nozzle Work?

A rotary turbo nozzle spins a zero-degree spray tip in a 4-8 inch circle at 3000 rotations per minute. This spinning water jet strikes surfaces from multiple angles, efficiently breaking down dirt and grime. As a result, rotary nozzles can significantly reduce cleaning time.

Rotary nozzles attach to a pressure washer lance using specific connections and cannot be connected to other water sources like garden hoses.

Why Sizing a Turbo Nozzle is Important

Choosing the right turbo nozzle is similar to selecting spray tips. The aim is to maximize the pressure output while also increasing the coverage area of your pressure washer. A nozzle with an orifice that's too large will dilute the pressure; one that's too small will break under higher PSI. The wider the orifice, the lower the resulting pressure.

Turbo nozzles work in conjunction with spray tips. You can adjust the pressure by using tips with wider cleaning angles if needed. For example, a 25-degree tip will produce lower cleaning pressure compared to a zero-degree red tip.

How to Choose a Turbo Nozzle

To size a turbo nozzle correctly, select the orifice size based on the GPM (gallons per minute rating) and PSI requirements. After selecting the orifice size, consider the following:

• How will it attach to your pressure washer? (Inflow Coupler)
• Is it rated for hot water and cold water? (Temperature Ratings)

Typically, the coupler is a 1/4" male snap coupler, but this may vary. Always read the product description closely to ensure compatibility. Assuming any turbo nozzle will work universally is incorrect and can lead to problems.

The orifice size decreases with higher pressure requirements. For instance, a pressure washer operating at 3 GPM and 1,200 PSI would need a turbo nozzle with a 5.5 orifice size. Most consumer-grade washers can produce an average of 2,400 PSI. So, if your washer handles 2,400 PSI at 2.5 GPM, a 3.0 orifice turbo nozzle will suffice.

Professional-grade machines can generate up to 5,000 PSI. While a 3.0 orifice may work, you'll need a thicker turbo nozzle to handle the increased pressure, otherwise, the internal ceramic parts might break. This is where PSI ratings are crucial for sizing turbo nozzles.

What Are Turbo Nozzles Made Of?

Most turbo nozzles consist of ceramic, alloy, aluminum, stainless steel, brass, and plastic. These materials optimize and maximize the pressure output from your pressure washer, making cleaning faster and easier without additional effort.

While turbo nozzles are durable, incorrect sizing can crack the ceramic internal core, rendering them ineffective. Thus, proper sizing is essential.

How to Use a Turbo Nozzle

Once you have the right nozzle, connecting it is usually straightforward, often involving a 1/4" quick connect that attaches to your lance in seconds. If you need to change tips and have a quick-connect attachment, lift up the retaining piece, insert the new nozzle, and release the retainer to secure it in place.

After connecting the turbo nozzle, start the pressure washer and begin by spraying near your target. Gradually move closer after testing the pressure. You'll quickly adapt to the circular cleaning pattern and increase your cleaning speed.

Remember, running your pressure washer without pulling the trigger can damage the pump or cause overheating. The turbo nozzle does not act as an unloader valve, which prevents this damage. Always turn off your washer when pausing to be safe.

When done, carefully use a pin to clean the nozzle and tips before each use.

Common Applications for Turbo Nozzles
