Pressure washer attachments greatly enhance the ability of a pressure washer to become a complete residential or commercial cleaning tool. With everything from rotating cleaning nozzles to specialized angles of spray and extending wands, the ability of customization to the specific project is becoming virtually unlimited. Among the few different types of pressure washer attachments are various sub-categories which begin to get extremely specific: spray nozzles have been outfitted with sand blaster attachments; chemical injectors can come with foaming functions; turbo nozzles and couplings can be designed to magnify the pressure output. However, the basic types are fairly simple.
1. Turbo and Rotary Nozzles
Turbo and Rotary nozzles add power to the spray capacity by creating a circular spray pattern. The extra agitation magnifies the cleaning power and creates different varieties of nozzle for all sorts of cleaning applications.
2. Spray Nozzles
Spray nozzles allow for a directed flow of water or for a wider fanning spray. The nozzles are all identified by a four or five digit number stamped on the nozzle where the first two numbers indicate the degree of angle for the spray and last two numbers indicate the standard orifice number of the actual nozzle opening. The gallons per minute flow is not indicated.
3. Trigger Guns
Trigger guns are a light-weight attachment to the pressure hose of the washer allowing for pinpoint control over the spray and are great for use on larger jobs since many come with locking devices. These attachments really help when using hot water as the trigger gun can handle temperatures up to 300 degrees F and hands can be protected.
4. Telescopic and Extension Wands
Extension wands are a one size extender for the pressure washer blast. Telescopic wands come in pieces which allow for more versatility with higher and lower extensions. When using either style of wand it is important to remember a balance between a lower pressure level for control and the ability to still clean the surface. Practice is often needed to master long extensions.
5. Gauges and Adjustable Thermostats
Gauges allow users to be able to view the pressure building up inside the washer in the same way that thermostats allow the temperature to be viewed. Gauges are helpful for being able to avoid internal pump damages, cavitation, pressure spikes and the like.
6. Chemical Injector and Soap Nozzles
Chemical Injectors and soap nozzles allow for any type of chemical to be added to the pressurized water flow. Chemicals can help remove built up dirt and grime as well as grease or stains. With a chemical injector there is no worry about the chemical internally clogging the machine or being in contact with the pressure since the injector sits above the spray hose and adds the chemicals externally.
7. Couplers and Connectors
Couplers and quick connectors are designed to allow for easy attachment and detachment of accessories to the pressure washer without hurting the gaskets or internal O-Rings. Pull back on the collar on the socket half and either remove or insert the coupler plug. A safety lock then slides into place allowing for the pressure to not effect the junction.
