This training course covers the RTO competency-based training as required by the current Australian Standard AS/NZS 4233.1-2013 and AS/NZS 4233.2-2013. A Class B machine is any Jetter with a pump that is 5,600 bar litres and above. Most water jetters today are Class B machines.
If you are not sure if your machine is Class A or Class B, please call us and will help you 02 9674 9088, or complete this simple calculation:
5000psi jetter at 22lpm. Convert to bar pressure first.
5000psi divided by 14.5 = 345 bar.
345 bar x 22lpm = 7,950 bar.
This is above 5600 bar litres making it a Class B machine.
Any pump under 5,600 bar litres is considered Class A.
