    Hello-

    After a great deal of research, along with many answers to my questions provided by you, my Coltri/Nuvair MCH-6 compressor is here.  This is the 220 version (8014) and is actually less expensive to buy from Nuvair than the similar Daystate model, that was just released.  Additionally, the Coltri/Nuvair is a true dive compressor, set up for breathable air.  Should we ever want to sell, potential buyers include the entire dive community, in addition to air rifle/air pistol shooters.

    During the purchase I spoke to the good people at Nuvair (Craig, mostly) repeatedly.  They answered all of my questions, and gave me many different options.  In the end, my compressor was configured exactly to my specification.  I found it very important that Nuvair test runs all of the compressors they sell, before they are shipped.  Shipping was fast, and acceptance of the delivery, easy.

    I selected this model, over the Coltri Compact/Daystate type 2 based on Craig's recommendation.  Basically, the Compact/Type 2 is designed to travel in the back of a vehicle on a regular basis.  This model is designed to be stationary, costs less, and is easier to service as there is no cage to remove each time service is needed.

    Rather than upset my spouse, by sharing her clothes dryer outlet, I am having a dedicated 220 line installed next week.  A full review will follow.

    Kind regards,

    Hello-

    No problem, at all- $2700, plus $149, shipped to my door and delivered to my garage.  90 lbs. It has a 1 year warranty.

    Here is the closest one from Daystate, minus the breathable air filtration-

    1 last question: is that a gallon of oil for the compressor in the clear plastic bag next to the compressor?…

    Hello-

    Yes,  Coltri/Nuvair does make a 110 version.  I chose the 220 version, for my personal application.

    The problem with 220V compressors  configured to run on 110V is that they require 30 amp circuits.  Check the specs out on the Coltri MCH-6. Their website specs show the 110V version draws 29 amps. Very few household 110V circuits are wired for 30 amps.  Halving  the voltage on a 220V motor draws double the amps.  If you connect one to a common 110V 20 amp  circuit it trips the breaker or overheats the wiring which is extremely hazardous.

    good heads UP ..humdinger…would hate to have an added cost..to install 220v..or a 30 amp circuit…

    daystates 110 is still at the top for me with all the research for home compressor.

    I have never heard of this company, and know nothing about their product.

    I actually almost pulled the trigger on one.  I could not get it configured the way I wanted.  Also, it is a very new product, from Coltri/Daystate, and does not have a reliability history.

    Thank you, I want that same compressor for the price you paid.  Can you please let me know where you purchased the compressor from?  Also can you tell us what kind of fitting was on the end of the fill hose?

    Hello-

    I purchased from Nuvair, in California.  I only use 3000 PSI, so I requested the 232 relief valve and the DIN 232 fill whip.  My understanding, though, is that the DIN 300 fill whip in the US ships without the nipple and can be used in DIN 200 applications.

    The electrician will be here tomorrow!

    Kind regards,

    Did you get a chance to use your new compressor?  Waiting for the alluded to review:)

    Hello-

    The electrician did his job, admirably.  He understood what was going on, and went out of his way to make sure that everything worked well, when I fired the compressor up.  He inspected the inside of the electics box, and made sure everything was connected properly.  Really, he made my life easy.

    The compressor, itself, was test run, per the instructions, and I have filled two dive tanks with it already.   Interestingly, I found that the dive shop filled both tanks to 188 BAR, not 200 BAR, on my very last paid fills.  No more wasted money.  Waiting for my next fill to do a more complete review.

    Hello-

    I have been using my compressor for a little over a month, now.  Before writing this post I asked myself what information can I provide to others that is not already in written, or video form.

    First, here is a link to the manual for the compressor-

    https://www.nuvair.com/manuals/MCH-6_r00%2001-2015.pdf

    Second, here is a link to the videos that describe operation and maintenance-

    Finally, what I have to offer-

    The compressor is really quite simple to use.   I am very glad that I did not spend extra money on the automatic condensate drain or the automatic shut off.  They simply are not needed for most routine fills, that are not from empty.  I find that I can hook up my tank, start the compressor, and fill each tank in about 5 minutes. (I am filling from roughly 150 BAR to 200 BAR.)  Once I reach the desired pressure I open the condensate drains, close the valve to the tank, and shut off the compressor.  Then I simply purge the air relase valve at the tank, and I am ready to go.  It really is that simple.

    I am attaching a photo of the quick reference page I hung up in my work area, which explains this process.

    As a recommendation,  I simply would not waste additional funds on the auto drain, or the auto shut off.  If you are using this compressor you are probably like me, and you will stay beside it until your tank is full. Also, Nuvair is a big enough company that has the knowledge, and know how, to provide support for this machine, in North, and South, America for years to come.  That means a great deal, to me.
