Currently we have a lot of 4gpm 4k psi skid mount machines that I have purchased for the business and after careful reflection, I do not want my employees to have that amount of power at their fingertips. I am looking for a solution to giving them around 500psi - 750 max while still giving them the ability to wash the house and reduce their ability to cause damage with pressure.
These are the things I have considered.
Only give them soap tips and have them bypass the injector when rinsing
Some sort of low PSI chemical pump attached to the engines
Adjust the unloader to run at low pis (not sure if this ruins the pumps)
Anyways any input on this would be awesome. I would also like to have a proportioner if possible. 12v pumps are not an option because of the super low psi and I prefer an engine.
@Racer
Have you encountered less mist and pressure? I have only used the m5 twist with the injector right at the end of the gun. Do you know the range of psi at the end of the gun?
