Pressure Washer Nozzles
Pressure washers are considered and known by many as the best invention made when it comes to cleaning hard to remove dust, dirt and grime on hard or solid surfaces. However, very few people know that it is the nozzles that are responsible in making a pressure washer versatile. Pressure washer nozzles are indispensable accessories for a pressure washer unit and are the most functional attachment. They are responsible in regulating the spray coming from the unit. There are actually different types of nozzles and each can help to tailor the stream of water to suit your specific cleaning task.
If you are looking for a new pressure washer nozzle, always remember that not all these products are made the same. Different nozzles are made for different purposes and this could be anywhere from cleaning dirt and mud, stripping paint and graffiti off walls, or blasting away rust and oxidation off from different metals. The efficiency of a pressure washer will depend on the type of nozzle that is being used for a particular task as the angle of the spray pattern is very important. In addition, the power of the nozzles will depend on the type and power of the unit you are using.
If you look carefully, you will find some numbers stamped on the nozzles themselves. These numbers are in fact industry standard identification numbers that indicates the spray angle and the size of the orifice. The numbers are commonly four to five digits long. The first two numbers indicates the spray angle of the nozzle. For instance, if the first two numbers say “25,” it means that the spray angle of that nozzle is 25 degrees. The next series of number on the other hand indicates the size of the orifice. For instance, if the next series of number says “34,” this means that the size of the orifice is 3.4 in size. This size can be referred to as the PSI level of the nozzle – an indicator of how much water pressure is produced.
If you plan on cleaning something using your pressure washer unit, it is important to consider the type of cleaning you need to do so you will be able to choose the most appropriate type of nozzle. It common sense that the narrower the angle, the more power there is as the spray is directly concentrated on the surface. As the angle of the spray gets bigger, the lesser the power you get, but you also have more coverage area. The list below will show you the angle, the color, and what specific applications you can use the nozzle for:
• 0° spray – this is often comes with the color red and creates a pencil-like stream of water which can generate the highest amount of pressure. This spray angle is perfect for many heavy duty cleaning applications such as removing rust and oxidation, caked mud and cement form construction equipments, or for washing glue or tar form pavements.
• 15° spray – this often comes with the color yellow and is commonly referred to as chiseling tips due to the angle of their spray pattern. You can use this nozzle like a scraper to strip off paint from walls, molds, or mildew. You can even use it for cleaning the stubborn dirt and grease from your lawn equipments.
• 25° spray – this often comes with the color green and is the perfect type of washing tip as it has both power and surface area. This nozzle can be used for sweeping dirt and foliage on flat surfaces, or you can use for cleaning the roof and pool. Others even use this for removing any dust or particles from walls as preparation for paint application.
• 40° spray – this often comes with the color white and has the widest angle of spray. Although this nozzle has lost of its power, the wider dispersion of spray makes it perfect for light and sensitive cleaning. It is perfect for rinsing and for cleaning cars and windows. They are the most appropriate nozzle for cleaning wood fences, patios, and other delicate items.
There are also specialize types of nozzles that are perfect for specific cleaning jobs. One of them is the gutter cleaner which is an attachment that has been made to specifically clean the inside portion of gutters. Everyone knows that cleaning gutters can be dangerous as you either need to climb the roof and go near the edge to clean it, or climb up a ladder that is near the gutter itself. With the gutter cleaner however, along with a telescopic wand that elongates up to 24 feet, you can clean your gutter with your feet firmly planted safely on terra firma. This is possible as the gutter cleaner has a curved neck which allows you to direct the pressurized water onto the gutter itself. This will allow you to push the leaves and other debris that are trapped inside.
Another specialized nozzle would be the turbo nozzle. Turbo nozzles can provide you with more cleaning power as these nozzles generate a spinning like motion due to the pressure of the water itself. This rotating motion mimics the scrubbing action we do when we are cleaning by hand, which in turn provides you with more cleaning power.
Pressure washers are by no means simple and dandy equipments as they are able to generate great amounts of pressure which can be dangerous if they are not handled properly. When handling a pressure washer, regardless of the type of nozzle that is attached to it, make sure to never point the wand at yourself or any other living thing for that matter. The pressures these equipments can generate are enough to peel your skin and cause irreparable injury. Always treat a pressure washer unit as if it were a loaded gun. When trying to replace the nozzle on the unit, make sure that the unit is turned off and always make sure that the nozzle you replaced is locked in place so as to ensure not just your safety, but also the safety of those around you.
