moisture trap problems

I have recently started using my airbrush and although I have a fairly good understanding of how it works and have used it good results, last night i was having LOTS of problems with moisture. I no longer have any kind of instructions for the compressor. It is a testors tankless compressor and it has a moisture trap. The moisture trap typically has some water droplets in it, last night it had a lot more dropplets, not like there was accumulation at the bottom or anything just lots of dropplets. I figured out to unscrew the bottom and attempt to blow out the moisture but the trap never cleared completely. After doing this i could paint for about 2 minutes before the problem came back. Our relative humitity has been low at about 57%. I have painted with much much higher humidity with out issue. Am I over looking something? Any Ideas. I'm painting with Pollypaints and am thining with Tamiya acrilyc thiner at about 25% thinner. I'm using an Aztec brush.

Thanks
Paul
