Coltri MCH 6 Owners, get in here, this thread is for you!!

[Harv24]

We have an Alkin thread, so we need a Coltri thread. Tips, tricks, I just ordered one and I'm looking for info on wiring it, the plug, what you did for the 220V service. Pics are great as well.
C'mon Coltri Brothers!!!! Unite!

 

[Airgunmann]

All I had to do was install the plug end to the MCH 6 I had 220 in my garage all ready

 

[Harv24]

Do they come with a Plug? or do you need to add one.

And yeah, Craig is still there and was awesome. He sent me my quote last night and I talked to him on the phone this afternoon when I placed my order.

You could run from an electric clothes dryer outlet if you have one, and it’s convenient. Just a quick way to get up and running if you can’t install a new circuit yourself, or are waiting for your electrician.

That's what I do. My wife just LOVES it when I hijack the laundry room to fill my tanks. Lol. God bless an understanding and patient spouse.

If you go the dryer plug route, check your receptacle and get a compatible plug from the hardware store. It's easy. On the "Alkins owner" thread, there are multiple posts where guys chip in and show how to wire on a 220 plug.

You will need a 30 amp 2 pole breaker and a 30 amp outlet and plug using 10 gauge wire. The 230v Coltri motor is listed at 17 amps and code says you can't exceed 80% of the breakers capacity. 80% of A 20 amp breaker would be 16 amps. Make sure you have room in your breaker box for a 2 pole breaker. I just topped off my Great White from 3400 to 4500 in 5 minutes.

 

[Harv24]

So I already have a 30amp 2 pole breaker in my Panel. It's been inactive for years (It was an electric water heater-I've converted to N Gas)

Coltri says I need a 35amp. I'm tempted to just use the 30 amp. Then all I need to do is buy a receptacle and a plug and wire them up.

Do I need the 35 amp? When I asked Craig , he told me it would only be for the high draw at start up.

 

[mr. earl]

Mine is on a 30 amp. I would like to hear what others say. Eaton compressor has a chart showing what size breaker is needed for compressor motor HP and they say 30 amp for a 3 HP. You can always replace the 30 with 35 if you want. The 10 gauge wire on the 30 is plenty for a 35. Do not start it under a load. I let mine come up to almost the tank pressure before I open the tank valve. This also give the desiccant time to absorb the moisture.

 

[Airgunmann]

On mine there is a check valve on the line to the tank so you can open your tank and it doesn't let pressure go to the compressor so I open the tank and turn on the compressor

 

[Harv24]

Some pics of the check valve and plugs would be super helpful.

 

[Airgunmann]

I would but I'm not home right now I have a 300 din hose connecting and a couple different adapters for foster fitting and scba filling the plug is just a 3 prong welder plug top to are sideways at like a 45 and hot wires and bottom is the ground

 

[Airgunmann]

Plug I put on mine is this

 

[Airgunmann]

The check valve was installed from nuvair

 

[Harv24]

Here is what Craig from Nuvair recommended when I emailed him.

 

[beerthief]

have a 220 Radial arm saw so ...................... but no coltri

 

[BlackICE]

The startup current of an ac induction motor is like 7 to 12x the running current for short <.3 seconds. I hooked up a current probe to an oscilloscope to measure the startup current of my a/c compressor. Running amps is about 17 but start up current was 150 amps. The a/c is on a 50 amp breaker. Breakers don't trip for short over currents.

 

[Str8tshooter]

Did Nuvair happen to mention any difference between the MCH6 (discontinued?) and the new ICON?

 

[Scotchmo]

The Icon is still an MCH6. I think the main difference for the new MCH6 is a die cast monoblock (as opposed to sand cast?).

That would be a reasonable change, especially if they plan on making lots of them for a long time. More expensive tooling but faster production with more consistency. Thinner walls possible on the die casting, so lighter, but hopefully not too thin.

Edit: I watched the videos and it sounds like Coltri has updated a lot of their manufacturing processes. Older blocks were done in a permanent mold, with sand cores. Cylinders heads, rods, etc were said to be done the same. The parts for the newer models use die castings and forgings. And lots of other little updates.

I have one its a gas unit, fills fast , I built a little table wagon to move it around...fill station, one bottle ..4 guns.
life's good.
