GX CS4 Compressor - Initial Impressions

[Bayward]

I wouldn't recommend 15 psi input unless you want to prematurely wear out and break your compressor. I use 3 PSI and if I only fill to 300 bar that's no worse of a load on the motor then filling all the way to the 350 bar that is capable of.

Do you know what flow rate you get at 3 PSI? Thank you for your input.

I don't know the flow rate, but the output of the CS4 is a little more than stated in the manual. I measured the power used by the CS4 to set the pressure level. I set it so it is below the maximum power reached testing with the dead head plug to maximum pressure 350 bar when I fill to 300 bar.

I have a couple fittings ordered for my CS4-i. They will be here Thursday and I will try your method.

I just got the notification that the CS4 is out for delivery a day earlier than the tracking showed yesterday. It is an excellent thread with lots of helpful information.

Adding an edit for one more question. How long have you been using nitrogen to feed your compressor?
My reason for asking is when I was trying to find the fitting thread size I emailed GX support. The answer they gave me was do not do the mod as the compressor could not take any pressure on the inlet side. I am guessing they thought I was going to release the full charge of a nitrogen cylinder into the compressor instead of a regulated 10~15psi I plan on using. Or less psi if I get a good flow rate at less psi.

I have been using Nitrogen for going on 5 years now Starting with a GX CS2 that I fed at 5-8 psi , I now mainly use a flowgauge at 25cfh/13lpm
I still use the gx cs2 with a 20cuft nitrogen bottle for use in the truck.

Nice, where did you order yours from?

I ordered directly from gxpumpofficial. When I saw the sale, they were initially out of stock. The in-stock notification was within two days, and they shipped very quickly.
