2024 CS4 SETUP

Noise started around 250bar, gauge is way off on the compressor, which was expected.
Yeah, definitely no clicking on mine like that. How long ago did you twist the grease pot? (Also, what grease are you refilling it with, if you have that much time on it yet?)

My FX M3 and my SCBA tank are nearly spot-on the same as regards pressure. If I set my CS4 to about 265 bar, I get 250 in the gun. Still playing around with it. Gonna mess that setting up tomorrow when I top off my Great White 97L tank.

Only have 2.6 hours on it, so I didn't touch the grease knop yet per the instructions.

Ahhh, you're only 0.4 hours ahead of me. Good to know.

Took a little over an 1/2 hour to top off my 97cf from 3600ish to 4500 with 2 purges.

I'll report back tomorrow if I am able to fill my 97. Or whenever I do get it filled.
 
I made the external 4 foot (actually 2, 2 foot sections joined to make 4 feet) desiccant tube described earlier. You won’t need to drill any holes in your compressor case. Just run the suction tube out through the slot where the power cables exit the case.

That should work well. To ensure that the compressor is working as efficiently as possible it would be prudent to connect a vacuum gauge near the air intake to the compressor to measure the pressure drop from the long path the air takes through the beads.

I'm doing something similar to this, but have about 1/2 PSI and a short tube going into the input port.

Did the bulk of the work with a dremel, then finished it off with a file until the meter fit the hole.

Finally got around to filling up my Great White 97CuFt tank. (Did one run the other day from 220bar to 240bar, took 30 minutes.). Finished it off tonight from 240 bar to 302 bar. Took 57:42, and temps are shown below in order of Ambient, Coolant, Head, and Motor:

Then I disconnected the SCBA and hooked up the gun, leaving the fan running. Took the gun 7:42 to go from 155 bar to 252 bar:

Far too early to get excited yet, but I can't help but feel like the GS 4 is not even struggling.
 
So I received my CS4 on 19 Feb 2024. Took the case apart to install an hour meter (which didn't work like I wanted it to, so ordered a different one).

Removed the small pre-filter and installed my homemade one with color-changing silica beads in it. (Two 3/4" PVC caps, tube wrapped with electrical tape to make a snug fit. Intake end has holes drilled in it, output end has a 3/8" brass pipe fitting to mate with the brass elbow into the compressor head).

Had some rusty water inside the bag when it arrived. No large debris in the water tank, but I flushed it about five times with tap water until it ran clear (was a little murky at first). Then put some Dawn dish soap in the reservoir and ran it for a couple of minutes, then began flushing it. After several fill/run/flush cycles, it was running clear. Then I purged the system completely of water, and finished by filling it with 250 ml of distilled water.

Connected some LED strips to the coolant hoses to make the water flow easy to see when running. Soldered them to the pump contacts so that they come on when the power switch is switched on.

Also added a 4-sensor temperature logger, but one sensor (to the motor) is faulty. Waiting on the seller to get back to me on a replacement. Have the sensors on the Head, Coolant tank, Motor, and Ambient air for tracking purposes. (Temps are - MHCA - Motor, Head of cylinder, Coolant tank, Ambient)

(Temps after 30 minutes)


Currently running the compressor for two hours with no load, though I saw nothing about that in the owner's manual, only saw it here on AGN. Where did this info come from?

Sadly, mine is one of the non-fluted cylinders. Darn the bad luck!

Parts:
Hour meter #1: (returned because it is too large and the backlight won't come on when the power switch is turned on) - https://www.amazon.com/gp/product/B0C539D7R8

Replaced with this one. Smaller footprint, allowed me to install it in the back of the lower case, as opposed to the top cover, which would require disconnecting wires every time I opened the case:
