Seperating tank and compressor

by Adryan

I want to separate the tank from the compressor and install the tank in another part of the building (don't have the room for it).

At the moment the pressure switch is on the tank.
Can I install the switch in the pressure line going directly from the compressor to the tank, of must I install a new small buffer tank near the compressor and install the switch on the buffer, to eliminate any pulsation?

Compressor is a 3Kw V-twin.
Vessel is 270 ltr

thank you,

Unless you use a very small pipe to the tank, the pipe itself will act as a tank and absorb most of the pulsation.

I'd go ahead and do it, then if you find pulsing to be a problem, you can always add a local tank.

Also, if the pipe is very long, it can act as an after-cooler, and you can put in a drip line near the tank to keep the tank relatively dry.

Install pressure switch on tank or line
by: Bill

As far as I'm concerned, as long as the line from the compressor pump to the tank is unimpeded as to flow and pressure, the pressure switch can be installed anywhere along that line.

The pressure switch will "read" the pressure in the line, yet the pressure in that line cannot increase to the cut out level until the tank is, too, full to cut out pressure, so it should work just fine.

The pages about adding a tank on this site will help further.
