Thread: Scrubber filters

  1. #1

    Scrubber filters

    I have built a homebuilt scrubber for a rebreather project.

    Any suggestions as to the best/easiest available pad material to hold the sofnolime in place.

    Currently using a cut out piece of "chux" (dish cloth) - am thinking of getting lab filter paper.

    What do others use in homebuilt scrubbers?

    I have never built a RB and probably have no business posting this, but I always figured that a filter from a coffee pot would work very well.

    If someone tests it out, let me know how it works.

    The homebuilt scrubber I've been diving in my Meg for the last 5 years uses stainless steel screen that has approximately 50% open area.

    You can't use an homebuild scubber until you have a way to test it with proper gear.

    How about a couch and an observer followed by an exercise bike and an observer for the DIY version of CE testing?

    Re: Scrubber filters

    I was just assuming that some kind of stainless steel screen would be used. I was thinking of using the coffee filter to make a more definite stop for any dust etc.

    Re: Scrubber filters

    For my radial scrubber I just used a stainless fine mesh placed directly inside the stainless perforated outer shell. I also use the mesh on it's own for the inner screen held inplace with 2 stainless rings (think napkin holders).

    For my smaller pendulum scrubber I use industrial scotchbrite, I've also used those cheap green kitchen scourers too.

    As for the small dust I just fill carefully and give it a good shake. I've not had a problem with dust (as yet). I do though use a small round disc made from scourer between the scrubber and the breathing hose, in the bottom of my P port.

    Regards
    Gareth
