    MCH? And nitrox stick for an independent

    If you order a compressor with an auto shutdown, hour meter or auto drains, then the electric connections will go into the controller. The controller is located in a convenient place on the frame and the power cable comes out and runs to your electrical panel. The compressor does not come with...

    New filter stack ideas for my Bauer Mariner 190

    The Coltri system is a good one and, while I would love to sell you one, it would be a major pain to pipe up. I second Ian's suggestion for original equipment.

    MCH? And nitrox stick for an independent

    Motor controller does a few things . First, it gives you a start/stop switch so you don't have to use your breaker switch. It also gives you a distribution panel for things like an hour meter, auto shutdown, auto drains, high temp shutdown, etc. It also prevents the system from starting if...

    MCH? And nitrox stick for an independent

    Just a quick note on your budget. While you can just squeak in with the MCH16, the MCH13 will give you a couple of hundred to do some of the things that have been brought up here.

    Large Booster (ag30,ag15/30 etc) vs Coltri mch6 3.5G omnibooster

    Just a quick note on that MCH6.. The $2500 one is a standard gasoline model. We bought too many and still have quite a few waiting to be sold. Normally, that wouldn't be a problem but the gas engine has changed on the 2020 units. Electric and 2020 gas units are still on sale for $2700 base price

    Compressor Envy

    Don't bid more than you can afford to lose. It is a gamble at best. I got two compressors for a great price and when they showed up, they were both frozen. One was the engine and the other was the compressor.

    More MCH 6 questions (quietening, filtering and time to fill)

    Do not put rubber washers on any of the bolts. While it may cut down on noise, it will also allow some movement of those bolts and that can lead to breaking supports and braces.

    Compressor I'd help

    What type of service are you talking about? Oil, filters, valves, etc are VERY easy to work on as long as you know what end of the wrench to use. And as for the motor, it is an easy job to pull off the three phase motor and install a single phase motor. 7 1/2 hp tells me it is an MCH16 and...

    Good compressor for infrequent use?

    Are you a veteran, retired or active duty? There is the Veteran's Day sale going on right now of $100 off or free shipping to the freight depot closest to your home. It ends at the end of the month if that will help.

    Good compressor for infrequent use?

    I would go with an air conditioner instead. Cooler air is drier and it is also much better to help keep the compressor cooler.

    Good compressor for infrequent use?

    $2700 is a special because we misordered and got a huge shipment into our US factory. As soon as the Italians and the big brass at the factory get back from DEMA, I will know if it is still going on. Even though I will make more per compressor, it will be hard going back to the original retail...

    Good compressor for infrequent use?

    That $2700 compressor is the MCH6 that is listed on my site. The retail price is $3581 but it is on sale. I really don't know how long the retail price is going to last. The Italians are at DEMA now and we have to see what they are going to charge us for the next year. On the Mako, just...

    Good compressor for infrequent use?

    At $2000 for a used unknown, you are about $700 away from a brand new compressor with a warranty. And, with your usage, you are looking at about $75 a year in oil & filters

    Yong Heng compressor + breathing air filtering

    About three hours. This system is a $200-300 Young Heng with a mini tank and regulator all in a very expensive bag. $1000 is a big way to a real compressor.

    Vintage Aerotecnica Coltri MCH-6

    I bought a compressor system from a store that went out of business and took the filter to a compressor specialist and he asked if it went out because hi customers kept dying? :wink: The filter stack consisted of a plain 4" pipe with flanges held on both ends by threaded rods. The nuts on both...

    Vintage Aerotecnica Coltri MCH-6

    The carbon filled cartridges were the European standard for years. They then went to all Molecular Sieve cartridges. I think they only started doing the tri-chem cartridges in the last few years. I had a bunch of them that we pulled out when we would get the container in from them. The...

    Vintage Aerotecnica Coltri MCH-6

    I f you are going to be filling beyond 2250, I suggest a new gauge and fill yoke as both of yours are designed for 2250 psi. Oh, and an air sample only really tells you the quality of the air at the time you sampled. Anything can happen to make bad air as soon as you start up again after...
