Compressor Selection

Jump to latest Follow Reply
If you already have a decent size shop compressor, I say go for it. I've had one for five years and the problems I've had have been my fault. They operate very slowly and produce no heat. They don't cause your bottle to heat up so the pressure it stops at is the pressure you get. Also, Ondrej is very helpful if you do have a problem and always answers his emails. They are definitely slower than a scuba compressor but for the money, I think they are worth considering.

Found out through my electrician that my 220 outlet isn’t hooked up even though there’s an outlet in the wall. Looks like it’s going to be an omega for me.

That's extremely strange. Did he check the panel to see if there were wires there, perhaps just not connected to a breaker? Are there wires if you pull the outlet out?

They do make some half-height 110V breakers that could help you free up some space. I don't care for them, but if you're desperate...

You'd have to pull four existing, adjacent, 110V breakers and replace them with two of the half-height duplex breakers. That would leave two slots open for a 220V breaker. Due to the way power is distributed to the breakers there's no such thing as a half-height 220V breaker, so it needs two complete slots.

HTH,

I have also been looking at the altaros unit to add to my preexisting compressor. Anyone have any reasons not to get one ?

Mine has done way past 100hours and runs 100% on original parts (there is a complete rebuild kit included when bought!).

Slow = yes, Reliable =yes.

But for the most part we PCP shooters has breaks in our shooting that allows time for slow bottle fill.

So you bought a Yong Heng and Omega Supercharger? 

You're rolling the dice on the Supercharger.

You should REALLY buy Knife's Altaros as a backup.

I didnt bother to check this thread again since I had read you already decided to buy the gas Coltri MCH6 earlier but I guess not.

Top of the line version of the Omega Supercharger-

Do NOT BUY a Daystate 110. It must be the Coltri MCH6.

There's more bad Omega Supercharger failures on AGN compressor section threads

I only searched a few because there's over 200 pages when key word Omega Supercharger.

It's your hard earned money but I would CANCEL that Supercharger order because I don't like to gamble since I am personally batting 0 for 1 regarding the Omega Supercharger and 0 for 3 in regards to compressors costing over $1200 so far. I personally lost roughly $4000 to date on failed compressors and with 2 I managed to sell as-is for cheap like the $500 Omega Turbocharger guy I posted the link to. My Omega Supercharger was a TOTAL $2000.00 LOSS with all of the shipping I paid I couldn't even sell it because UPS even lost it (or stole it) and did not honor the $2000.00 insurance I paid them then they said their system updated and could not find my claim nor tracking history and I even gave the local UPS office the original receipt I paid which they apparently lost too. How convienent I no longer have any evidence to take UPS to court for the loss.

I purchased an Air Venturi 4500 compressor about two years ago. Recently, it would not produce any pressure. I discovered the low pressure cylinder reed valve was broken. I cleaned all sealing surfaces and replaced the reed along with new gaskets. It will now my 100 cu in tank but takes longer than usual. I also noticed the high pressure coil (coiled tube) no longer gets hot which it should. I've checked the burst disc it's OK and cannot detect any leaks. After nosing around on the internet, I suspect the high pressure piston seals (rings) may need replacing. Before I order the parts from PA, does anyone have any other ideas that would cause a slow fill?

Thanks... Tom

Tom,

Be sure to buy the $12 ring installation tool when you buy new piston rings. They are very stiff and you need the cone part to help stretch the rings open to slip over the piston. DO NOT stretch the rings completely over the cone, only go about 3/4ths of the way then stretch them over the piston. The other part of the tool compresses the rings back down over the piston. Be sure to leave the split silver base that is under the existing rings in place.

While you're at it, make sure you clean the two reed valves on the high piston side to remove any burnt oil residue. One of the reed valves is inside the round disc in the piston sleeve above the piston. You won't see it until you punch out the disc from the top of the piston sleeve assembly. Get a copy of the exploded schematic on this forum to see all of the parts and how they go back together. The reassembled piston sleeve won't work if you don't line up the exhaust holes in the disc correctly. You may wish to take pictures before you take the piston assembly apart.

I found that replacing the piston o-rings and cleaning the reed valves was the step needed to build pressure. Make sure there are no hose leaks after you reassemble or you won't be able to build pressure in spite of your efforts.

Humdinger,

Thanks so much for the information. I have the installation tool and rings in my PA cart now. I found a video on line, a VERY long video but it was helpful. I'm new at this forum gig so I wouldn't know where, or how to find the exploded schematic on this forum. Can you guide me to it or send me a link? I've been all over the internet looking with no luck. You provided me with information I wasn't aware of and I thank you. Hope to hear from you soon.

Tom

Humdinger - you are a veritable font of knowledge about compressors! And I mean that sincerely. Perhaps you've remarked on it elsewhere, but I'm curious about your history or background. How did you come to be so knowledgeable about so many compressors? 

For those reading, this is not at all a challenge, or a 'calling out' - Humdinger is someone I would heed in all matters compressor related. I have *some* knowledge (perhaps experience is a better word...) myself, but have learned a lot from HD and his remarks are invariably right on the money.
