Alkin W31 vs Bauer Oceanus E1 - A Review

[tmassey]

IMHO, no compressor should be without continuous CO monitoring. Take an old first stage, plumb into compressor output, use a 3 lpm flow meter to blow on $100 CO detector. Even if you had to buy an old first stage, $200 or less.

Hey Rob, thanks for the tip on the Lawrence Factor chart. I found it under "Heat Wave" on the LF website. And I remembered that Alkin sent me an email that the 50 hours was based on 20 degrees C... Which is 68 degrees F. From the chart, if I'm running my Alkin in 80 degree F temps, multiply the 50 hours by .65 and I get 32.5 hours. That's still a LOT of filter life but the chart fills in something specific instead of "filter life will depend on temperature and humidity."

Interesting that the chart shows MUCH more filter life if I run at temperatures BELOW the 68 degree baseline. If I run at 50 degrees F, I multiply the 50 hours by 1.81 and get 90.5 hours!

Home Made Moisture Checker - A friend on another forum came up with this.

Hi SurfLung.
Happy Christmas. Lucky for you its a friend on another forum and not your idea.
My stand on this contraption you won't like but first consider the required application and put the above idea down to these clueless farm hands on the paintball and airgun forums.

Anyhow can you first check the written details on your photo I think it's going to be another China import selling kitchenware out of a warehouse in Brea California called DrynDry also better known by another name. If so we can kick off 2024 with a bang.

I really strive to fill below @ or below 50F, anything lower is a bonus (but above 30F to keep anything from freezing). It's amazing when you punch in the numbers and realize that heat eats through a filter ridiculously fast.

The way I've run mine on paper I can get close to 2 years. At 50F the inlet at the filter would be theoretically 68F and my filter nets 20,000cf @ 68F. I have also used a infrared gun and my tower only raises by about 11F over ambient, so that's better then what LF figures into their calculations.

I also never depressurize the filter tower. I have seen some people do that, no idea why?

Agreed, continuous CO monitoring is crucial for compressor safety. Your setup suggestion is practical and cost-effective. Using an old first stage, a flow meter, and the $100 Forensic Detectors CO monitor creates an affordable safety system. It's a smart investment for any compressor operator, potentially costing under $200 total. Thanks for sharing the review link - it's helpful for those considering this setup.
