    Can anyone on here recommend a budget compressor option to supply an air fed mask?

    From what I have read a piston compressor is not suitable despite multiple oil / water traps due to oil blow-by, what sort of compressor would do the job most cost effectively?
    The output from booth is already sorted as is other air supply for gun so looking for standalone solution.

    Any advice appreciated
    Cheers
     
  2. All you need is a proper filter set for breathing air. A 3HP compressor will likely be required, but it depends on the mask's requirements.

    You can use a piston compressor, but you need specialised filters to provide breathable air. The obvious option would be an oil-less compressor.

    In my own case (grit blasting) I used a car heater fan and replaced the original pipework with a large bore vacuum cleaner hose.

    If you're paint spraying though I'm not sure whether my set would have been safe, but maybe you could use the same principle with a bigger fan?

    Thanks this what I was hoping but from what I've read it's advised against, perhaps just the big co's H&S scaremongering

    Cheers I'll consider that, like you say likely not suitable in the form you had as I would need a decent positive pressure maintained, I'll have a look into it
     
  5. It is how the majority of commercial sprayshops work. The key is in getting the correct filter pack, designed for breathing air. Make sure that the compressor has a clean air supply too, not pulling overspray in.

    I have a small nardi twin piston oil-less compressor which is suitable for scuba diving, of course it needs a filter to stop metallic taste in the air but it works really well. It has no tank, the air is kept inside the frame...I use it for framing as it’s portable and packs a punch !

    It’s a nardi compressor, although mine is blue...
