    What size compressor do I need?

    Hi,
    I'm looking to get a compressor to run some tools - riveter, impact wrench and a spray gun. Mostly I'll be doing hobby stuff like fixing up trailers and farm machinery.

    There are so many compressors to choose from I'm stumped. Do I want a big tank with a low hp or do I want a small tank with a bigger hp. Price seams to be a balance of the two. I'm not a professional so cannot justify forking out big $$ for something that will mostly sit in the garage.

    Love to hear what experience you've had.

    Mine is 2.5hp, 298L/min, 175L/min free air delivery...about a 50L tank I think. Runs a small sandblaster, spraygun, air tools, middle of the range type of thing, cost about $500 10yrs ago or so...probably get them for less now. Seems to do all I want for a home compressor.

    I have just downgraded from a larger, older compressor to one very similar to what you describe & it is working just fine . Similar use to what you need .

    I bought Peerless 10 years ago
    Big tank means less starts and stops
    Lower RPM means go forever and reduced starting current

    P14 Portable, 275LPM, 10AMP ? Peerless Products

    Hi Gullible , I got a Westair FAD 235lpm 54lt tank .
    Smaller than the old one , but does all I want .
    Westair is a WA company , if not readily avaliable I would probably have gone with Peerless , BOC or Repco .

    On compressors

    Having moved into a house recently , with neighbours - perish the thought , I got a shed built and have equipped it with all sorts of goodies,

    I have your typical generic direct drive chinese type compressor which I have hooked up to an air line to distribute to points around the shed, But the noise of the compressor was concerning - or I thought it might be to the neighbours ,

    I was all set to buy a noiseless compressor - at 5 x the price of a no-name when I saw some guy using an oil filter screwed to the end of a rifle as a noise suppressor - you know where I'm going , most noise on a compressor is induction noise.

    I cobbled together an adaptor and screwed a Z9 to my compressor , ( just had to dig out the anti drain back valve - probably un-necessary ) .... ah the silence , plus theres enough filter media in there to last forever .

    the pink bats screwed in behind wire did had a marginal benefit, would not have bothered with it if I'd fitted the oil filter muffler first.

    That looks like some fancy anvil you have there. Do you have a patent on it?
    Not sure, but it looks like a piece of cut down steel tramline.
