    Re: Scrubber filters

    I have used what I think is called a "splatter pan". looks like a tennis requet (smaller though) and the inside of the "racket" is stainless mesh. It is used to prevent oil from panfrying splattering everywhere.

    Use a new one off course

    Cuts and shapes very easily, and cheap as well

    Those are usually aluminium mesh. Take care to make sure the one people pickup are the stainless one that Pretorius has.

    I assume aluminium reacts to make H2?

    Im pretty sure hypercapnic ventillatory response is considered pretty safe, and the couch / excercise bike test is fairly well standard? Generally people can tell way before its fatal?

    Self testing hypoxic ventilatory response is a bit more risky?

    You need:
    a CO2 analyzer
    A breathing gas flow of 40 lt/min
    A CO2 Flow of 1,6 lt/min
    Some way to test all at 5 bar

    Re: Scrubber filters

    Are you using any particular grade of stainless steel for the mesh?

    Re: Scrubber filters

    I used a preforated bread pan for a filter. It cut fairly easily and was heavy. I was sure it was stainless. After 3 dives, I had a little mishap with my mouthpiece so I checked the sorb on my homebuilt and there was only a couple of little pieces left on the intake of the first scrubber. I'd avoid aluminum.

    Re: Scrubber filters

    I know this is an old thread, but I was reading and doing some research when i stumbled upon this thread. In one of my earlier posts here, I mentioned using a coffee filter for a scrim in a scrubber. Well, since then I have actually tried one and the WOB was terrible.

    DO NOT USE COFFEE FILTERS

    Bounty paper towels will work to get you by in a pinch, but I do not recommend them for long term use. Don't ask me how I know.
