Choosing The Right Pressure Washer Nozzle For Your Cleaning Needs

By Edited Feb 6, 2014 0 0

Pressure Washer Nozzles

In order to use your pressure washer nozzle most effectively and safely, you need to consider not only the type of nozzle that you are using, but also the ideal spray angle for your application. Although pressure washers are extremely powerful cleaning devices, if you fail to do a little research first then you will risk either not using enough pressure or using too much. In this article, my aim is to help you understand how different nozzles are rated for spray angle and orifice size. Additionally, I will provide a short, easy to understand list of different angles and their ideal applications.

Determining the Angle and Orifice Size

Before shopping for pressure washer nozzles, you will need to make sure that it will accommodate your needs, providing enough spray coverage and a proper orifice size for the job. Most nozzles have a standardized system written right on the unit, usually consisting of 4 numbers.

The first two numbers represent the angle of spray supported by the nozzle, measured in degrees. For instance, the number "25" would mean that the nozzle can cover a 25 degree arc. The last two numbers represent the orifice size, expressed in inches. With this number, you have to insert a decimal point in the middle in order to get the right measurement. For example, a "35" would mean 3.5 inches.

How to Determine the Right Angle of Spray

Generally, a narrower angle means a more powerful spray. A 0 degree angle is most appropriate for the heaviest applications, allowing the user to remove extremely tough stains on concrete, surfaces that are high overhead, or getting tar off of pavement.

Moving up a setting, the 15 degree spray angle is a little gentler than 0 degrees, perfect for washing off heavy equipment or stripping away chipping paint. Additionally, this setting can be used for washing away marine life from the bottom of a dock or other environment that is in close proximity to a body of water.

Next, the 25 degree setting is much gentler, perfect for cleaning a roof or the side of a boat. Also, a 25 degree angle is suitable for washing a surface in anticipation of painting a surface.

The lightest setting is 45 degrees. This is the one you can use to clean windows, washing small boats, etc. Remember, if you are going to attempt to clean a window with a pressure washer, be sure you carefully read the instructions for both the washer as well as the windows you have installed at your house.

One last note: Make sure you choose your washer carefully. In addition to standard washers, there are also steam pressure washers, appropriate for applications which require more temperature power than a normal hot or cold water washer. By doing a little due diligence in your research, you can obtain the perfect pairing of washer and nozzle, allowing you to perform your cleaning task as efficiently as possible while minimizing the risk of damage that can result from inappropriate settings.
