[PSUBS-MAILIST] Scrubber design and materials

[via Personal_Submersibles]

Best use a radial fan for more pressure. Axial fans will stall.

I use this one. https://nl.rs-online.com/web/p/centrifugal-fans/7125244/

Nice job David!

 

I've also put together my secondary scrubber for Gamma.   

I ended up picking the quietest fan I could find: https://www.amazon.com/gp/product/B012CL2V3I/

It's seems to be putting out a good amount of air, but I'm not garage-dived tested it yet.

I'll get rid of the USB connectors for something more marine worthy.

 

I'm also wanting to try some IP rated fans, but seems I may have wait a few months for them

to ship.  I've attaching the fan with a 3D printed adapter to it's easy to swap out and test different fans.

 

Also interested to hear folks scrubber media recommendations!

 

Thanks,

  Ian.

Hi Guys, just completed my scrubber for the VAST sub. Its capacity is right at 3lbs, based on my rice test. I see I can purchase soda sorb online but was wanting recommendations on where to purchase it or the draeger product. Since this is my first scrubber, I have no experience with the different products. 

David
