[PSUBS-MAILIST] Manual Scrubber.

Wed Apr 22 07:32:45 EDT 2015

James,
It is funny, I was just about to ask the same question.  When I saw Alec's mouth piece arrangement, I figured I better get on that so I also ordered a mouth piece.  My question now is, will you have a check valve to make it easier.

 Hi
 James,

 There is a fan inside the scrubber at the base, but it
 also work without turning the fan on. We see several
 advantages in the full manual mode: power saving, robust in
 case of power failure, and also better scrubbing.

 regards,
 Antoine

 Ahhh, hi Antoine.  Sorry, I didn't
 realise it was you the Pilot fish guy.  Ive seen the pics
 of the scrubber with the counter lung.  Is there a fan or
 anything drawing the air through or is that all
 manual?

 Hi James,

 no I have not yet, but you ll find pictures on the
 Pilot Fish Project facebook page, March 10th post.

 I have a scrubber made from Emile, and as Emile
 said, when you exhale through it the reaction is much more
 efficient.
 You may or may not need an intermediate counterlung to
 buffer the flow, depending on the breathing
 resistance.

 regards,
 antoine

 it.
 Thanks

 James,

 Blowing
 is the best . You exhale warm , moist, and CO2 rich air
 through the scrubber.
 Air
 exits with almost 0 % CO2 !

 [PSUBS-MAILIST] Manual
 Scrubber.

 Hi
 all,

 Im rigging up
 my scrubber with a mouthpiece for manual use.  I have one
 of Emile's scrubbers so the fan is at the bottom pushing
 air up and I have a hose at the top that directs scrubbed
 air into the tower.  

 All i'm
 going to do is attach a mouthpiece to the end of the
 hose.

 With the fan
 off, should I be breathing in, sucking air through the
 scrubber?  or blowing exhaled air into the
 scrubber?

 Plus im
 thinking that if im breathing in, I should maybe have some
 sort of particulate filter to stop
 dust?

 How it is now
 without a mouthpiece.

 Any
 suggestions?

 Many
 thanks

 James
