This will depend on your applications and how much you want to be prepared for future more demanding applications.
The low temp VT work will need something. Sometimes a $500 wall tube type is enough for work at 4C.
You need this at a minimum and if you're like me, you want a prefilter/bulb to catch the odd particulate, water overload, or oil drop...
Depends on the dryer and filter at the compressor.
If you really need a -40C dewpoint for work around -10 - -20C, they are about $1500 (bigger cartridge, Parker-Balston is good).
If you need -100 dewpoint for below -40C, it can run $4-7k and then you need a ballast tank to keep the sample from bumping up when they cycle between cartridges.
There are lots of folks with more expert opinions here but that's my 2 cents...

Subject: ammrl: Air Dryer
Hi all,
We, the department, are in the process of installing a new 500. One of my concerns is to put an air dryer. Because of the dry weather here in Utah, I would appreciate to hear from those in the Rocky area about:
1. What kind of air dryer they use or would suggest?
2. Does anyone even take a chance by not using one?
Thanks in advance,
Simon
