    Frank,
    As ususal, you are the MAN! This could really be great for this machine. 

    Mrod, we all are rooting for you! In the end, I think you will have a good product. You have great ideas, however, your planning and delivery system is what brings you criticism. Not saying I could do any better, planning costs time and money (more than anyone ever realizes). The “problems” you are experiencing are no different than FX or Daystate when they launch a new product. When you are an individual vs a Corp, however, it becomes more personal for the good and bad. 

    For thoughs who have partnered with you I would encourage them to continue working with you to “fine tune” their machines. I believe you are behind this product and you will do everything to make things right. I do think there will be some initial “bumps”. I would encourage those with a problem to contact you directly. If you are unable to correct the problem, then they have the right to report their experience on these forums. If you are one of the first to purchase this “new ” product you have to realize there will be things that will need to be modified. You also need to understand that Mrod is but two people where a Corporation has a “bunch” of personel. Please allow them the necessary time (which I am sure is more than you want to give) to correct the problem. 

    In my opinion, this compressor is in it’s infancy stage and may need further modifications. Like your P12 rifle, I believe you will make improvements which can be added to the original model to greatly improve upon it. If I am incorrect about these statements, I offer my apologies  here and now. I think you have taken on a very large task and put yourself “out there”. Unfortunately, there is just and unjust criticism coming with that. 
    I wish you best of luck on this venture!

I’m still waiting for my royalty checks to roll in… 😉

    I’m sure the poor fellas at MRod are working night and day and feel like they’re under a microscope…because, well they are.  It’s a ton of pressure to be sure.  They’re doing way better in their business ventures than I am though, so I won’t criticize.

    Thanks Guys,

    Lets all try to stay positive, it gets you further in life every time.

    We are not perfect, but we try our best.

    With input from the Forums like this one, we can steadily improve both our logistics and the quality of our products.

    Being small has its disadvantages, but it keeps our prices low, with far fewer mouths to feed.

    By this time, we are starting to get a bit of traction in the market and as always we owe that to our customers.

    At Mrodair, we make every attempt to correct issues we see, in the time we have.

    It can be a delicate balance.

    We very much appreciate your business and support.

    With the cooling upgrades and fact that it isn’t a cheap o-ring compressor like the Omega, it is the best option for those that don’t take the huge leap to a big unit like a Shelden, Airtex, Daystate, or Bauer. What is the actual CFM rating of this compressor? The true SCBA units start around 2.4CFM. Just curious since the Omega, Alpha, and Shoebox are so slow they are measured in CFH not even a full CFM and would be a good comparison for potential buyers.

    It is difficult for me to say, as we do not have a flow meter to give you the hard data.

    I can tell you it is every bit as fast as our Mako 3 phase dive compressor at the shop.

    These new compressors, as our customers will tell you are amazing in how fast they fill tanks.

    Perhaps one of them would have access to the equipment required to measure this accurately.

    This is important information to know! This should have been part of the planning stage ( which costs money to measure of course) and would fall under just criticism for not having the information. I understand it brings the cost up yet it puts you under scrutiny for not having this information! Fast is a very relative phrase and is inadequate for a description. I have read reviews on the Shoebox where people say it is “fast enough”. I am certain Daystate has this information for their compressor. 

    I am not trying to criticize you at all, just helping you understand why you are getting negative feedback right now. Once the first buyers get their compressors up and going, I would hope they will post positive feedback and neutralize any negativity you are getting right now.

    NM shooter,

    I sincerely appreciate your input.

    Many of our customers, have already posted their feedback on our compressors and their fill rates on several forums.

    We ourselves, post on 5 forums in the US alone.

    We have also posted the manufacturers fill rate, however in use we find them much faster than advertised and those rates are not applicable to the actual performance of our new compressor.

    We have videos using this compressor and state our exact pressures, fill times, and capacities on small medium and large 118cu tanks filling from various pressures including zero.

    I am certain from the information we have already provided, the fill rate could be extrapolated.

    The important facts are how fast does it fill at full pressure in an Airgun usage application.

    All of this information was done prior to these compressors being available in the US and clearly posted on our website with links to the videos.

    It is “real world” testing and use.

    We feel in our application (airguns) this information is more valuable.

    I only asked for CFM for a direct comparison since all other units have listed CFM or CFH and those ratings seem to be accurate to the fill rates they produce. At one point you responded that your compressor would fill my Tiger Shark tank which is 71cf and my guppy that is 18cf as fast as my 2.4cfm compressor does. That made me assume that the new Airmax is around 2.4cfm? I read a post on another forum that someone had asked for reviews and someone gave a little mini review and stated 15-20minutes to fill from 2700-4500 for a 30minute scba bottle. If it is a true 30minute bottle it is around 44cf. A 30 minute bottle from 2700-4500psi will take around 5 minutes on my 2.4cfm compressor. Based on your previous info of the compressor and reports by dman, the info i just read on the other forum must have not been timed or the person isn’t sure what size bottle they really have. Having an accurate CFM rating for the Airmax can help people make an educated decision. Since you already have a customer that posted a time that would lead folks to believe the Airmax is much slower than advertised. Please understand I mean no ill will, just trying to point out something that could be of benefit. When I bought my compressor, comparing CFM was a major factor in my purchase.

    I understand brother.

    We filled our larger tank as well as others, on video, so no issue with “belief”

    Just for reference, a large 118cu 45min SCBA from 1950psi to 4500psi was 26-28 min fill (we fill from 1950-2000 to 4500 often)

    When filling 13cu, from empty to 3000, was under 2 minutes.

    Hope this is helpful.

As an FYI  – a Compressor that is putting out 2.4CFM at 4500 psi will (or should) fill a 30 min bottle from empty in 18min and 20 seconds.

If you timed the 118 cuft bottle from zero to 4500 you will be able to determine the CFM at 4500 rating.

    Right now, based on using 2 minutes to fill a 13cuin bottle from 0-3000 the fill rate at 3000psi is .8CFM. A 13cuin bottle is 1.6 cuft. If it takes 2 minutes to fill to 3K then it is putting out .8cuft per min at 3Kpsi.

    I have a Shelden that is rated as a 2.4cfm. I time all my fills and just took a stab at filling a 30 minute bottle as I don’t have and have never filled a 30 minute bottle. Was just a guess. I usually top off both my tiger shark and guppy when they are down to 2900-3200psi and top off both to 4750psi as they cool to near 4500psi. I fill both back to back and allowing 30 seconds to a minute after both are filled for the compressor to clear any moisture out of the cylinders, I end up with 10-15minutes of total run time.

So the whole Idea here is to get people to go to your website to get the info? Thought Micheal warned you to not advertise?

AJ – based on my calculation (obtained by some info on the web) a 2.4cfm compressor should take approx. 10.9 minutes to raise 89cu ft of air from 3K to 4500psi, which is right in the middle of your estimated 10-15 min.

    Yes, typical 3000-4500 has always been right around the ten minute mark. Since I rarely have both tanks at the same pressure when I top off and since bumping the shutoff to 4750, 10-15 minutes covers any and all fill ranges thus far for my 2 tanks.

    Our compressor, on a tank that size, reported and posted on the forums already from 2800-3000 to 4500 is between 15-20 min.

    Several of our customers have posted near identical fill times.

    Once Again, hope this helps.

As an FYI – according to the MSA website the biggest tank they make is a 60min, which is 87cuft. If your tank is a 45min tank then it is 66cuft. In either case it is NOT 118cuft.
    Judging by the size in the video my guess is 66cuft. Which a 2.4CFM 4500psi compressor will fill from ZERO to 4500 in 27.5min

    Went an watched your video and in it your “note” indicated it took 1min and 40 sec to fill your 13cuin (1.6cuft) from ZERO to 3000psi. Based on this the CFM of your compressor (at 3000) is .96.
    1.6cuft /1.66min = .96 cuft/min (or CFM)
