You would need to look at the head curve on the datasheet to determine the actual flowrate through the fan/scrubber. It would be substantially reduced due to the pressure drop through the CO2 absorbent section. Also to meet ABS rules, you need to size this unit so the that the current draw is not so great as to pull the emergency battery down before reaching 72 hours of life support. On my boat, the hotel load is about 1.5 amps (life support and comms only). The emergency battery has a capacity of 110 Ah at 24V so a 1.5A hotel load will last 73 hours. I did a garage test to confirm.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Cliff</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"><br></div><div><br></div>

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. <div>David</div></div><span style="font-size:10pt;">
