Air Dryer for Yung Heng Compressor??

I just got a Yung Heng Chinese HP air compressor. It works like a charm, but has no effective air dryer on the output. There is a small filter cartridge in the line going to the air tank and keeps oil and dirt from getting into the air tank, but I dont feel confident that it'll do much for the moisture in the HP air. What are you using to get the moisture from getting into the tank, and from there into you PCP airguns?
