Which switch for wolf compressor

[breezer]

Hi all, the diaphragm in my wolf compressor has ripped, they're not available as a separate unit so I need to replace the whole switch unit.

Machine mart sell a 1 port 20 amp version or a 4 port 20 mp version.

How do I tell which one I need (or does it not matter)

Cheers

Jim

The no. of ports refers to how many things you have attached to the switch.

1 port connects to the tank and then others may connect to a regulator, safety valve, pressure gauge and so on.

If you're not sure get the 4 port one and some blanking plugs for the unused ports, or post a picture to give us a better idea.

Ah, cool - sounds like I need the 4 then.

Comp has tank (obvs), tank gauge, regulated gauge & safety valve.

Presume regulator & gauge would take up 1 port not 2 (otherwise that would be 5)?

Thanks for your help

The regulator gauge measure the pressure on the outlet of the regulator so it's connected there rather than to the pressure switch.
