The Daystate LC110 Compressor report

@humdinger, The only explanation I can think of is that the 4 stage LC110 draws slightly less current than the 3 stage. From what I remember, Steve's unit tested on AEAC was a 4 stage unit. @kahr40 unit above photo shows 14.5 amps, whereas mine shows 15.2 amps on the label plate. Enough difference to trip a breaker that is close to the limit.



Mine is identical to kaht40’s. It is 3 stage and the label says 14.5 amps. It has a 330 Bar pop off valve and auto shut off. Centercut is either connected to a 20 amp circuit or his is running on less amps after break in. Mine is no longer tripping breakers after installing a 20 amp circuit and outlet where the compressor is run.

Mine is stamped 15.2 amps and I'm using a 15 amp breaker. I only tripped the breaker once... and that was when I put an extension cord on it and brought it outside. I have a little over 7hrs and zero tripped breakers. I make sure nothing else is consuming power on the circuit before firing up the compressor... so far, no issues --Carl
 
Yesterday I installed a new outlet in the crawl space where I run my compressor using 12G Romex on a 20 amp circuit. I'm all set and no more worries about tripped breakers when approaching full pressure.

Here's a cheaper and simpler way to use your existing Daystate fill hose without spending $60 for a heavy 300 DIN to a Foster quick connect. It is much lighter and less cumbersome to use. There are lots of different JIC sizes but the adapter size required is a 7/16" JIC male to 1/8 NPT male adapter. Grainger Supply has them for $1.58 rated for high pressure. The Grainger part number is 6W433. Here are photos of the before and after with the parts labeled. If you don't have a male foster on your tank you can just connect two hoses that have quick connects using a foster male to male adapter. Northshore Compressor also sells this JIC to NPT adapter.

I take it the filter that comes with the LC110 works. Bleed it every 10 minutes. What second filters are you using? Where are you purchasing them? Do you drain moisture from the second filter?

The most common aftermarket filter guys are using is the gold filter which is readily available on Ebay or Aliexpress. I recommend the newest Tuxing filter that includes a filter cartridge that can be refilled with desiccant and reused. It can be ordered from Aliexpress and ships from the U.S. for $76, including the cartridge.

These second stage filters remove moisture by containing desiccant which absorbs the tiny amount of residual moisture that may get past the primary moisture separator tower. $1000 plus compressor designs like the Daystate/Coltri, Bauer, Nardi Atlantic, Alpha Carette, Air Venturi, and Hatsan Lightning use a true cyclone moisture separator that bleeds off most of the moisture as it is pressurized and condensed along the walls of the separator. Full sized moisture towers drain 99% of any moisture and any residual water vapor will be absorbed by adding a desiccant filter. There is no need for a bleed valve on a desiccant filter unless you prefer to depressurize from the filter itself rather than depressurizing it by opening your tank's bleed valve. 

One of the major deficiencies in the $200-300 class of single piston compressors from China is the omission of an adequate moisture tower. They have very small moisture bleed chambers that allow lots of moist air through to the output hose. These compressors quickly saturate desiccant filters which weren't designed to capture the volume of water that a well designed moisture tower removes. There are aftermarket two stage gold filter moisture separator systems available from China that do the job that these economy compressors need. There is no free lunch in getting a well designed high pressure compressor.

Here are photos of the Daystate LC110 using a gold filter housing installed as a secondary moisture removal filter. It retains the factory fill hose but the 300 DIN is replaced by a quick connect attached by a JIC/NPT adapter fitting. Much lighter and cheaper than adding a pricey adapter to the end of the 300 DIN. Another inexpensive upgrade is the addition of a male foster with one way check valve at the base of the gold filter. This allows the air tank valve to be opened before the compressor reaches the tank pressure. Don't add this check valve to your filter unless you also have an air bleed valve between this check valve and your tank. Most tank valves do have an air bleed but some don't. Also, please note that a check valve does not act as a pressure maintaining valve (PMV) when filling an empty air tank. I had my tank filled from another compressor for it's intial fill so low pressure air would not pass through the filter. I've added a foot of clear 3/16" I.D. tubing to the separator tower valve to divert water vapor blast away from the compressor.

The compressor hose and it's 90 degree connector is moved from the tower and threaded into the output side of the gold filter using teflon tape. The existing 300 DIN on the fill hose can still be used as is if you prefer. It can be unthreaded from the compressor's fill hose and replaced with a Grainger adapter, part #6W433. Then you can attach it to a female threaded foster quick connect, or female threaded male foster if you prefer. I used two 90 degree 1/8 npt threaded male to female elbows at the output of the water separator tower and at the input side of the gold filter. I threaded a male foster check valve into the input side of the gold filter. I connected a 2' high pressure fill hose that terminates in 1/8 npt male threads between the tower and the gold filter. One side is threaded into the street elbow on the water tower. The other end of the hose has a female quick connect which connects to a male foster check valve threaded into the 90 degree npt elbow on the underside of the gold filter.

All of these are available online through hydraulics suppliers, Northshore Compressor, Ebay, or Aliexpress. Just be sure to buy 5000 psi or higher pressure rated fittings from whichever supplier you buy from. 
 
Steve, what do you think of putting the check valve at the connection from tank valve to fill hose, vice where you put it at the inlet to the gold filter? I think both have plusses and minuses, but keeping the maximum amount of connections protected from a rupture (and tank pressure venting through the rupture) is the major benefit of putting the check valve closer to the tank. My tanks have a male foster QD, but then if it was a check valve it wouldn't be able to be used for other than filling the tank (one way ointo the tank but not out of the tank).

So, I made a small double fitting, male foster QD check to female foster QD that I insert between the female on the hose and the male on the tank. This is only used for tank filling. I do like the way you did it, but it also brings into play the connection to the gold filter, the gold filter, the connection from the gold filter, and the connections/hose to the tank. Any of those mentioned in the last sentence fail and you have the tank venting back through the failure or rupture. With the connections as I did, your only potential failure that affects the hose whipping about wildly is a failure of the tank QD or male to female fitting I made. Just a thought? 
 
Your assembly idea is just as good as mine. In fact I also have one like yours that I made awhile back. The check valve is located to pressurize the filter from the tank instead of from pressure building in it from the compressor during each fill. I am confident that the gold filter and factory fill hose including the fittings on them are as fail safe as any other parts in the system. It is my poor man's PMV since I never will fill a tank from empty.
