is that continuous flow?
or on/off trigger duty cycle while cleaning?
(which and can and does vary per operator)
..L.T.A.
It was non-scientific as can be.
I laid on the wand for 30 seconds on each test and noted the temperature.... in my mind, which is clearly a problem.
I went back through the settings/wands a second time because I know my little HX is goofy at low temperature.
My blower was capped off for this
6 flow, 450 psi... max 170 degrees at about 20 seconds. About the same on the second go around.
8 flow, 450 psi... max 182 degrees at about 15 seconds. Again, about the same the second time.
4 flow, 450 psi... max 165 at about 22 seconds. Same the second time.
4 flow at 600 psi got to 185 around 15 seconds.
