  • A new home fill compressor

    CNG Specialists of Oklahoma is advertising a new home fill compressor. www.letsgocng.com There's no direct link to the compressor; you have to click on "CNG Home Refill". It's a single phase, 2gge, four stage, but needs AT LEAST 2 psi? The motor appears to be a three phase with a phase converter and the whole unit is exposed to the weather - it'll need to be installed under a carport or patio cover. Looks like it has two hoses for filling two vehicles at a time. Only $6800.

    I think they mean .2 psi minimum to 5 psi maximum. The only period in the advertising text is the one that looks like it is at the end of the previous sentence and the space is in the wrong place. I hope the compressor itself isn't the same Chinese four cylinder we saw a couple of years ago that seemed to fail faster then they could sell them.

      thats an Italian Metano compressor, I know very little about them but that small driven pulley on the compressor equals high rpm which usually equals short life.

        not necessarily as long as the oil/valve/filter changes are made accordingly

          1200 rpm is what the description on eBay says. Also says it is rated for 15 hr day run time and 2 GGE or more depending on line supply pressure.

            As I have always said on here... home compressors are RARELY practical. And "only $6800" stated above... is that installed? Permits required? Also, can the seller document at least 3 users with over 12 months of use? I'm willing to bet they can't. Who comes to fix it when it breaks?... and it WILL break and need maintenance.

                Even if you wanted to repair it yourself, there's probably not a service manual available or at least an exploded parts diagram with part numbers.

                  My experience is that the faster a compressor spins the higher the maintenance.

                    I sent an email asking these questions...."Is this a relatively new CNG compressor? Is there an available parts list e.g. valves, rings, etc? How many of these compressors have you sold? I live in East Tennessee, if the machine needs servicing, who will do the work? Do each of the 4 stages have pressure gauges installed? If I provide an inlet pressure of 4 psi, what would be my expected gge per hour?

                    They responded very quickly with the following email...."These are new CNG compressors and all of the parts are currently available for repair.If the unit needs repair you will need to return the unit to us and your unit will be repaired within the two year warranty without cost if the operable defect is from normal performance. The unit is set up to produce 2 GGE/hour with inlet pressure delivered is at least 2.0 PSI or greater. The increased PSI over the 2.0 minimum does not incrementally increase output but just insures that the compressor is not starved for gas input. Should the unit need to be returned to us, we will arrange for shipping and pickup. If the findings of disrepair are shown to be caused by the owner then the shipping cost will be charged back and the cost of the return is the financial responsibility of the owner. If you choose to purchase parts from us and do the repairs yourself that will void the warranty if done within the 2 year period following the purchase. There is only one pressure gauge built into the unit to show the output pressure of the compressor being delivered to the receiving tank(s) We can supply a separate gauge, for a cost, to measure the inlet pressure of the gas being supplied to the compressor. If the methane gas being supplied to the compressor is from a natural gas well on site then the unit may need a separate and bigger separator and filter to handle any oil condensates that may be present. Please confer with your supply source of gas company as to that risk of condensates. We have larger compressors available if you are needing more output per hour than this compressor is designed to do. It is not constructed to be exposed to wet conditions and will need protection from the elements. Adequate ventilation is needed for cooling and to vent any possible gas leaks. The company building these compressors has been in operation for more than 40 years. I am sure that they have sold several and we are very pleased with the product thus far with our sales.

                      WOW ... the compressor pump part looks a LOT like the Coltri MCH6 small 4 stage air compressor right down to the sump tap fitting location. Plus the speed is exactly half the RPM of our air compressor and half the capacity as well. Kind of makes you go Hmmmmm!

                        72-73 db - Hope you don't have neighbors close by.

                          I don't think it will bother anyone for TOO long. I have a feeling that noisemaker will be short lived.

                            That is actually not to bad. Our little gasoline engine driven model gives off about 82-87 ... mostly from the Honda.
