Coltri MCH-6

Well I’m making the leap into a much better compressor. Erick at Nuvair wants to know what type of fill hose I need and these are the choices he sent. What do I need to fill a .74 CF tank.

What type of fill hose valve device would you need?

- International yoke

- DIN200-300 bar

- DIN300 bar

- SCBA

- Paintball

DIN300 or paintball will work. If you have the paintball with a female foster you will need a fitting with a male foster on each end to connect the hose from the compressor to the hose on the tank. I like the DIN300, but, you have to unscrew the hose from the tank to fill.

I envy you!

It will be x-mas before i press the buy button on a MCH-6

Go with DIN 300 and you will do all the others if needed with an adapter.

Isn’t it inconvenient to remove the fill hose from the tank?. And is there any advantage?. Thanks for the pictures, they help.

not inconvenient at all, it’s only on hand tight, no tools needed.

The advantage of a DIN300 is that it is a more secure connection to a DIN300 female threaded tank compared to using a foster quick connect on the hose. A female foster quick connect on the end of the compressor fill hose requires the tank to have a DIN300 to male foster connector on the tank to complete the connection. The vibration of the compressor during fills will eventually develop a leak inside the female foster from o-ring wear. The threaded DIN300 connection is unaffected by vibration. So it is less costly if your tank has a DIN300 female connection, more secure, and is easily attached to the tank without tools.

Thanks everyone for your help…DIN300 is is the one.

You have any experience with the gas type?

I generally do not watch videos, because I would rather read content. Videos showing how to assemble, disassemble things can be of help, though, when working on equipment. It is time to replace the pressure relief valve on my machine. This video shows how the machine was made, and was of help. I was especially interested to note that no torque wrenches were used during assembly-
