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

Jump to latest Follow Reply
My LC-110 was purchased in 2019 and is a 3-stage design. I believe the LC-110 is actually this without the breathable air filter (as it is not needed unless pumping outside in humid unconditioned air):

Please note, unlike the Coltri MCH-3 on Nuvairs site, Coltri clearly states this compressor is capable of 330 bar.

As you can see it is a 3 stage unit and since, from a part aspect, the LC-110 should be 1:1 to the Coltri MCH-3 EM LC

LMNOP, I followed your link above and own an LC-110 3 stage Daystate as you do. The Coltri MCH-3 specifications indicate that it might have a 220 volt motor or a larger 110V motor turning 40% more rpms than the LC-110. The decibel rating on the MCH-3 is higher at 91db reflecting higher rpms and higher noise level. Also, the fill rating on the MCH-3 is 50 liters / 1.7 cubic feet per minute whereas the LC-110 is running at 78 db with a fill rating of 30 liters / 1.1 cubic feet per minute. It would be nice if the LC-110 had an hour meter like it's MCH-3 cousin. I wouldn't want a faster fill speed unless the MCH-3 has a different motor than the LC-110's 1 horsepower rating. In many respects I prefer the slower fill rate and lower decibel rating of the LC-110. It means that the LC-110 runs at a lower rpm and at a lower operating temperature which usually means better longevity. One of the best attributes of an LC-110 is it's relatively low noise level compared to most compressors.

Looking at the motor plate on the site, looks like a euro motor for 50Hz ~220V. I think the RPM still says 1680 RPM... hard to tell, the PDF manual says 1400 RPM for the MCH 3 EM LC that I uploaded. Matches the pictures in that link too. LOL who knows, Coltri and their manuals. The data bits always trip them up like with Oil levels. Site says 330 bar PDF says 300 bar, lol.

Either way I think the LC-110 is pretty much a Coltri MCH-3 3-stage low consumption variant that's been scaled down for air gun use... such as no breathable air filter, etc. If I had a valve plate break I'd hit up Nuvair for parts and wouldn't have concerns I couldn't fix it due to lack of parts.

I think 330 cc might be over filling these 110 units. I think I have about 250 cc and it's mid way up the dip stick. I know you don't want to over fill. What say you guys? Do you check the oil with the dip stick pushed home or just resting on top of the housing? One of my bitches no manual AT ALL came with my unit. Nothing said about warm up cool down. I suspect some of the trouble that's been had could have been avoided with a little effort to write a note or two too the buyer with instructions.

Hey bb64, check out my post history, I uploaded the LC-110 one-page note that came with mine. I think the 330mL/330cc is spot on, I check with the dip fully depressed. Did you ensure you removed the crank-case nut when filling? I over-filled my first 5 hour break-in period I believe because I used the dip and sight glass. The sight glass is inaccurate and shows low during 330mL but the dip reads true.

AOA has indicated 330mL is the goodness point and Coltri has YouTube videos demonstrating a measured 300mL.

Depending on how comprehensively you drain 250mL may be your "sweet spot". When I changed mine at 5 hours I did a tilted unlevel drain, flat, repeat, until I got no more oil out.

Thanks I'll have to check. Crack case drain nut? Well yes that's the nut that lets the oil out? There is another place you loosen when draining that would be the like a breather. I'll have to check. I think I drained a measured 250 cc so that's what I put back in. I tilled the unit up towards the drain pretty good. Of course when you put new oil in it's clear so it's harder to read.

I checked and it's a little on the low side. About a third of the way up from the low reading to the full so it probably could use a little oil. Thanks

Yes -- I removed the crank case nut when draining and filling, even though the manual mentioned nothing about removal during draining. It just makes sense to avoid vacuum lock. Equiv to removing the oil fill cap from an automobile before you loosen the oil drain bolt from the oil pan.

See the orange circle. It must/should be removed prior to re-filling with oil, this is in the Coltri manual:

The LC-110 reads at the top of my fill level on the dipstick fully seated in the cap holder using 300ml of compressor oil. If I added 330ml it would be well above the dipstick upper fill level. Mine was built before the sight glass version was being sold but it is a 3 cylinder version. I'll recheck my manual but am fairly certain it said to fill with 300ml not 330ml of oil.
