Daystate compressor

I haven’t seen any reviews of this compressor so I thought I would add mine.

I ordered from Jim at precisionairguns.com. Jim was pleasant to deal with and shipped the compressor pretty quickly. When I got it the box had been beaten up pretty badly, but it was well packed. There was some damage but it was easily fixable. The cage around the fan was a bit bent but I haven’t really messed with it since the fan doesn’t come close to hitting it. One of the feet on the bottom was backed out and it bent the tab that the foot screws into, but it was easily bent back and the foot was screwed back in with a bit of effort.

It took a few days until I had a 220 outlet ready in my workshop, but when I was ready I filled the unit with oil (provided. Make sure and use the manufacturer spec oil. It is NOT the same as shop compressor oil) I put the cartridge in the output filter and ran the unit. All was good except when I took my finger off the on switch the unit stopped. So if I hold the button in it works fine but when I let go it shuts off. Hmm, well I called Jim and he got looking into it. AOA (the importer) sent me a new switch which didn’t help and then they sent me an email with pics of the proper wiring. Somehow, two of the wires on the switch were reversed. Now YAY! it works as advertised, and work it does. FAST! This thing charged up my first tank before I fixed the switch, meaning I had to hold in the button (against a strong return spring) on a vibrating machine, but fortunately, the compressor took my tank from about 3200psi to 4350 (300 bar) in less than 5 minutes. This is a big, Great White tank, so I thought this was very fast. I have filled up several times since and it is very very fast.

Just a few notes: These compressors are made by coltri, an Italian manufacturer of dive compressors for many years. The chinese have a copy out there that looks very similar, but it is NOT the same thing. The rebuild time on these is recommended at 400 hours (not 100 as some have said) but after reviewing many diving forums, it seems these units have been operating in dive shops and dive boats for years with little maintenance and getting far more use than us airgunners will ever give them. Bauer does indeed have a slightly better reputation and longer rebuild times, but with my usage, I will be too old to shoot air rifles before this unit needs to be rebuilt.

The units come with a check valve (probably not the right term) that will open up once a certain pressure is reached. Basically this will prevent any over pressurization. Mine is a 300 bar valve. That translates to 4350 psi, but my great white tank shows 4500 psi when I am done. These can be ordered with different valves, so if having a full 4500 psi is important, make sure to ask about a 310 bar valve.

Despite the few glitches getting started, I absolutely love this compressor. It is extremely fast, relatively quiet, provides breathing quality, dry air and it is extremely well made. I believe that the price delivered to my door was around $2800. Having read some of the crap that mrodair people are going through, I would highly recommend this compressor, even at twice the price. I don’t have to worry about cooling or moisture in my air and I am shooting LOTS more since I can top off my tank in less than 5 minutes any time.

If anyone is interested in more info about this compressor, ask away!
