Rotor arms attached to the bottom of your surface cleaner.
They can be used for other applications as well.
The most common use is for underneath the housing
Of a surface cleaner and they come in various sizes
And styles depending on the size
Of your surface cleaner.
It is important to recognize the output
Of your pressure washer to be sure
It matches appropriately to your rotary arms.
Sometimes they are referred to as rotor arms or spray bars.
Typically you find an 1/4 inlet at the top
And you will either have a dual arm
Or tri bar or quad bar
Just as I have drawn up here.
And as you consider what size bar
You are going to use for your surface cleaner
It is important to realize the flow rate
Or gpm that your pressure washer puts out
It is of utmost importance.
It must match appropriately to the size
Of this attachment.
And so with a dual arm you have got 2 nozzles
We suggest you have a minimum of 4 gallons a minute
Giving you an output of 2 gallons from each nozzle.
Anything less than that will greatly diminish your productivity
And as you are pushing your surface cleaner
Along you may have a reduction of overall productivity
When doing your job.
If you have a machine that has a higher flow rate
5-6 per minute then you can use a tri-bar
Obviously more flow the more nozzles you introduce
You will get more flow out of each nozzle
And enhance productivity as a result.
If you are using a machine with 4
Then you will notice you will be greatly minimizing
The flow rate out of each tip
And by doing that you will have to make more slow deliberate
Passes over your surface.
So make sure you choose the bar
Based on the machine you are using.
8-12 is a much larger machine that can function
With a quad arm or 4 arm rotary system
And when you have 4 nozzles you can divide your flow
Rate up to 2-3 out of each tip
And this is typically found
In much larger surface cleaners say 30
Or larger where you will have a lot of volume and pressure.
The tips are generally 1/4 MEG style nozzles made of steel
This particular rotor arm is steel
But we also have stainless steel varieties
That you can get with 1/4 female pipe thread
Or you can also reduce the size to 1/8
And use a stainless steel bar
It is more expensive but you can reduce the size.
They come in various lengths of bars
So depending on the size of your housing
You need to ensure you order the appropriate rotor arm size.
It is always a good idea to check with the manufacturer
Or by calling us to help identify
The right rotor arm for your application.
As a always if you have any questions
Or concerns about what you are choosing on the website
Feel free to give us a call
To see what you need.
