Title: Air compressor for an old gauntlet 6 color 8 station?
Post by: Printitonup on November 21, 2016, 07:41:50 PM: Do you think this compressor is a good match for a gauntlet 6/8 press?

it's too small. Look for at least a 5hp compressor.

Post by: Printitonup on November 21, 2016, 08:22:08 PM: The hp is small. I have a 5hp compressor now that doesn't put out that much cfm.

This is new to me, I thought I could get away with this guy. Saw it as a package deal with a chiller used.

I wood think. 5 hp pressing it. I think.

Post by: jvanick on November 22, 2016, 07:27:32 AM: 5hp rotary screw, or 7.5hp piston...

a 5hp piston would be basically running constantly... which will reduce the life of the compressor head (and add a ton of heat that your chiller would need to remove)

the rotary screws are built (and like) to run constantly.

Post by: Croft on November 22, 2016, 08:52:41 AM: I had a "5hp" ( yes air quotes) tractor supply/ Sears quality level running my sportsman 6 colour ,It ran hot and after blowing it up I switched to a true 5hp commercial and never had any issue it ran cooler and better , it was single phase but drew more amps and needed a starter. When I moved too an area with 3phase I bought a rotary screw KAESER and its even better.

Post by: Northland on November 22, 2016, 09:03:11 AM: If you buy a piston style compressor.... consider a two stage machine. Preferably, one with a contactor that makes and breaks the motor current (using the air pressure switch is sub-par).

Additionally, most shops will use a refrigerated air dryer to pull the moisture out of their compressed air, to help avoid cylinder failures on the press.

Post by: Doug B on November 22, 2016, 09:03:55 AM: I also ran a 5hp temporarily during a move. It ran constantly with my old
Gauntlet. Another thing to consider is that (especially) with an older Gauntlet
there will be air leaks keeping a 5 compressor running all the time unless
all of the air lines and mac valves have been replaced.

Post by: mk162 on November 22, 2016, 09:07:48 AM: Yes, a chiller is a must...our machine tech was in yesterday and told me about the shop down the road that never drained their tank and finally started running water into the press.

So they ended up turning a pneumatic press into a hydro-aulic one. EVERYTHING had to get replaced. They had water squirting out of the stroke cylinders.

And don't forget to drain your tank.
