Has Anyone Received Their MRod Compressor

Jump to latest Follow Reply
"Irish"I received my airmax compressor today. Pretty quick shipping, but no indication that the order had been processed or had shipped. It just showed up.. Like others have mentioned there was oil all over the place. The box was totally soaked with oil. Also a number of wires had been pulled free. Some of them i'm not sure where they go. I have sent an e-mail in with pics and am waiting for a reply. My gun should be here tomorrow so hopefully i get a quick response..

How in the world are these still leaking oil? The "distributor" stopped shipping them with oil back in February.....didn't he?

Wires pulled free in shipping? after being "tested"? That's crazy

I assumed the oil was coming out of the low pressure head from being upside down at some point. I assumed all of the oil drained out upon receiving it. The crankcase bolt was tight. I filled it to the center of the indicator dot in the window. The few times I used it it made an oil cloud. I emailed Michael, and he quickly responded. He said I had too much oil, and it only took, "half a cup or so". It's about twice that to the center of the indicator dot. Then I watched the setup video again where his son-in-law said the proper fill level was just touching the bottom of the dot in the window. Then he said the levels are all different. I have taken out the excess oil, but I haven't used it since. It was spraying oil from somewhere the two times I used it. I can only assume at this point the oil causing the fog, and soaking my compressor was coming out of the breather that replaces the crank bolt. If this is true the units must have come over filled, and tested.

The oil isn't that huge of a deal. The box is absolutely soaked and the unit has quit a bit on it but i cleans up quick, and it looks to be nice clean oil. I had seen Ethers video on the unboxing so it wasn't a huge surprise. As for the wires, same deal, one of them was the power, The crimp came off the spade connector at the plug, once again not a huge deal, I think I'll solder both of them. The bigger deal was that I did spring for the automatic shutoff upgrade, and there are a couple of components wired and connected to the top of the unit, it looks like a big and a small breaker next to one another, both of those were hanging free, and a number of wires were disconnected or pulled free. 

I do have to say though, I sent an email off to Michael last night around 10 his time, and I had a response first thing this morning. So as far as that is concerned i'm pretty happy.. So I will call him later today and see what we can get figured out. The problem is I think one of the breakers broke it's mounting bracket, and also I'm not sure where some of the wires are supposed to reconnect.

Ether: Yeah in the video they say, that they asked for the compressors to come empty from the distributor or whatever, but they still are not, and that when the compressors arrive they have all different levels of oil, some too much, some too little. In Michaels e-mail back to me, he says that more than likely the oil spills came when the units were shipped to them, and that once they get them and test them, they drain them of oil to ship to us.

If Mrod tests them and they ship them oil free, where is the mess coming from? Why are wires broke off and other parts just hanging there? Unacceptable!

Well talked to Michael a number of times today, and he was very helpful.. I was able to get all the wires reconnected, and just ended up soldering a few to ensure they stay. I did have to use a couple of zip ties on the setup to attach the contactor back onto it's rail, not a huge deal. It does look like maybe UPS gave it a couple hard hits. The box was in good shape.. Like Ether I had to remove that secondary separator or whatever it is. I kept blowing out the o-ring. Not a huge deal for me because i'm in a very dry climate. All in all it took me about an hour to clean up and fix. It works like a dream. I just got a Wildcat and it recharges it in about a minute. So much better than hand pumping. Kinda wish i hadn't purchase a hand pump with my gun.. Oh well

Although I agree for the money this thing should be perfect out of the box, but on the other hand it's pretty much the cheapest option. I mean I considered a shoebox, but just couldn't justify the price of it vs. Mrod.. And the speed of this thing vs. a shoebox is no contest. I'm pretty happy with my decision.

I was able to get the secondary separator to close tight enough to keep the seal from blowing. The only problem is that to take it apart, and put it back together I have to take the whole unit and line off to open it with the aid of a vice, and a pipe wrench. It needs a slightly smaller o-ring in my opinion to be convenient. Maybe I will add some Foster fittings to the ends later. I only shoot the Drozd family of airguns as of yet so for me a little bit of moisture really isn't that big of a deal.

I replaced the O-ring on the secondary in-line filter, now it goes hand tight (very easy!) With metal to metal contact and mounted at the end of the fill line. This allows easy access to open and check moisture leakage and filtering (I found the silicon dessicant crumbling in separator). I added activated carbon for odor with my filter media and it works very well. I recommend you use it!

I made my own cooling system using re-purposed parts. I topped off my 80/3000 from 1500 psi with an average fill rate of 1.3 cfm. I stopped every 500 psi to drain the separator. After disassembling the separators I realized I should have done that more often. Anyway here is my cooling system. It seems to work very well.

What size of O-ring did you use and where did you get it? Thanks

"ether"I tried to run the fittings like you said. It sounded like a great idea until I ran into compression threads, and straight threads. The threads on the secondary separator are straight. All of my Foster fittings have compression threads. I decided not to wrench them in. Did you do something more?

The "compression" you are referring to is likely NPT (tapered). I've not seen any compression fittings rated for near 4500psi.

Ether, not sure if you are talking to me about the fittings, but I am trying to upload pictures to make sure our fittings are the same. I recall the air line going into separator just like without the upgrade and then installing the inline filter at the end of the line with the brass foster provided with the threaded nipple. I don't recall changing any fittings. I recall finding that the threads on all components provided, appeared to be metric and not BSPP or NPT.

Looknup, I have an O-ring set, so I am lucking to have an assortment. But I can tell tell you it was a automotive type and was a very tight fit that I stretched to slip over the threads and therefore reduced the diameter of the O-ring allowing fit within the filter case. I am pretty sure you can go to lowes and select one that will work.

Thanks for the heads up BTB. I robbed a paintball hose for the female foster fitting because it fit the nipples on my bottles a lot better. I'm glad I didn't force anything. 

Joe. I was also wondering how well the hose fitting would seal in the separator with the washer because it's not beveled like the male to male fitting. Also do you know the size of the o-ring you used?

The Oring is either 3/4 × 9/16 × 3/32 or 13/16 x 5/8 × 3/32 (113 or 114). The male to male fitting has a small Oring at cap side of inline filter (also finger tight). The separator connection has the sealing washer.

I've had mine about a year now. Very recently I wore the rings out on the high pressure piston. I emailed Mrodair, and was sent a set of replacement set. They were easy enough to replace, and now it's running like new again. What you should understand is I probably use my compressor a lot more than the average airgunner. I build Drozd Blackbirds to shoot four thousand rounds a minute. It often takes several 90/4500's to tune one so I have been using it in a commercial environment for as long as I have owned it. 

It's not the driest air, but that really doesn't concern me. I don't use any silica inside either dryer. I have the inline dryer mounted to the female QD. I simply pack it with cotton (the kind that has a paper ribbon in it that makes it a ribbon of cotton) and replace it every few fills. I will open the petcock to the dryer three to four times during a filling without shutting the compressor off. That works just fine for what I do.
