Hey guys...any opinions on the Daystate 110 compressor?

Jump to latest Follow Reply
Humdinger is spot on -- consider this; you've just spent your money on an investment into a mechanical device prone to eventual breakage. You have the ability to compress unlimited amounts of air given that you keep the duty cycle low and the machine well maintained. The less it experiences a high stress load at high temperature the less likely it is to sustain damage.

From a risk-benefit aspect pumping from 4500 PSI cut-off to say, 4700 PSI cut-off which is the point at which the Coltri/Daystate tea-pot blow-off happens, appears to be a negative ROI considering you could simply refill your bottle in a minimal amount of time.

I only have a 90 cu-in bottle with my LC-110 for the purposes of keeping the workload light.

Well guys am happy to show off my all new set up and I love my Daystate compressor.

Ok, you didn’t hear this from me but. Take an ohm meter and check to see if the cut off switch is an open or closed type. If it’s closed, then just put a jumper in the plug in unit. If it’s open, just leave it unplugged. This now makes this a manual control compressor so be very careful, you have to shut off the compressor yourself!!!!



Option two, change the cutout 330 bar unit, install the 310 bar and also due the above procedure. You now have a 4496.17 psi compressor.

Thing to remember 300 bar is only 4351 psi. This is why you only get about 4200 psi after cool down.



Another note, the 310 bar no electric cutoff switch is how Coltri MCH 3 was before this model. Read the operation procedure in the manual post in the above post.

Hope this helps.

I mostly agree with you bubblerboy64 with the caveat that the longer and harder the compressor works the more likely it is to experience failure. I don't think 4500 PSI is an issue for smaller tanks. I use two 90 cu-in tanks and top them off. I think what you're expressing, and I agree with you, is that the higher the pressure the greater the load. To top my tank off it takes 2 minutes of warm-up, 3-4 minutes of actual compressing, and 2 minutes of cool down. The time the compressor is working to achieve 4500 PSI is nominal compared to much larger tanks. It's all about work, temperature, duty cycle, and thermal build-up.

I believe the solution to longevity is keep the duty cycle light, avoid thermal build-up, and keep the compressor well lubricated with 330mL of oil changed often. Subjectively, oil is cheap insurance :)

I have about 7 hours on my LC-110.

After suffering a very short life on my Omega Turbo Charger, I’m having trouble justifying the expense of a $2000+ compressor just for my personal use. I need to fill my tank maybe twice a month. A cheap unit like the YH may be more cost effective. If it fails after one year, so what? You lose only 300 bucks. It would have cost me almost $600 to send the Omega back for repair. 4500 psi compressors are highly stressed machines operating at high temperatures. A recipe for failure regardless of price. Just ask a dive shop operator.

An understandable way of looking at things, especially considering the failure you note. But it seems that the most highly stressed compressors related to their level of "robustness" and considering cost are those in the $1000 to $2000 range. Compressors above that $2000 range would seem to be the most heavily engineered and most likely to function long term. Compressors like the YH can be viewed almost as disposable in that a person could buy 3 if needed for under $1000. Like most things in life, all relative.

I was corresponding with one of the US Coltri resellers while getting quotes. The rep seemed familiar with the Daystate 110, and said he recommended the MCH6 over the daystate equivalent MCH3 (not quite equivalent - the MCH3 comes with a filter that the Daystate lacks, factoring in the price of the filter their price was similar to the Daystate) because:

"The MCH-3 is a three cylinder compressor that came out a year ago. The original compressor is the MCH-6 four stage compressor. MCH6 is been around for about 30 years. They removed one of the stages and made it three stage. The four stage had a rotary design that balanced the load on the crank. Four stages on a small compressor is better than three."

I have seen some posts somewhere that stated that the Daystate 110 was 4 stage, some say 3 stage, and some say it has been both in different revisions. If this is true, what is currently shipping?

AofA originally sold the Daystate LC-110 in a 4 stage configuration. For whatever reason, the 4 stage units had issues. For at least the last 2 years it has been manufactured in a 3 stage configuration. I bought a new one in October of 2018 and it has run perfectly for me topping off a 6.8 liter SCBA tank. I added a gold filter and some plumbing modifications and change the oil annually after an initial 5 hour oil change since it runs less than 20 hours per year. I run it at least once a month to keep the internals lubricated and moisture free. It fills to 4500 psi and automatically shuts off. I do let it run for a minute or two with no load after disconnecting the tank to let it cool down and purge any residual moisture.
