Thanks, it's good to hear from yet another CO2 user.
I'm looking at a bi-directional filter dryer on Ebay.
EMERSON BI-DIRECTIONAL HEAT PUMP FILTER DRIER BFK-053S - eBay (item 230504732351 end time Jun-23-11 07:55:12 PDT)
And I'm wondering if this is the style/type dryer you're using?
Also, how do these things work? What's inside them?
Thanks,
Rich
