Questions & Answers

I plan to use 1/2 npt piping for my air compressor lines in my home shop. do I need to use the 1/2 in. npt filter drier assembly or could I get by with the 3/8 in. set up

Asked by: z28station
3/8 would be sufficient enough to use the air dryer in, you will not want to go with anything lower than that.

If we only use one bag of desiccant, I cannot see it through sight glass. So I put two in it. Will that cause a problem?

Asked by: Scott
The addition bag of desiccant will not cause any issues.

How much of the desiccant do you put in the Rockwood 1/2" NPT 2 stage filter dryer system. It doesn't really say.

Asked by: Scott
i bag of desiccant fits in this filter at a time.

How often does the Desiccant have to be replaced? Is the Desiccant you sell in the quarts and gallons what is needed to replace the Desiccant in the Rockwood 1/2” NPT 2 Stage Air Filter Dryer System Item #31727 that you sell?

Asked by: flyboydale54
The Desiccant sold in quarts is perfect to refill this system. As for how often it needs to be replaced this depends on too many variables to quote a time. The more humid your environment, the more often you use the system, and the volume of air the tool in question uses all play into how fast this desiccant gets consumed.

Would this unit be suited to keep the air dry for a Central Pneumatic 110 lbs. Pressurized Abrasive Blaster so the sand will not get moisture in it and clog up?

Asked by: flyboydale54
This would work perfect to hook up before going into an abrasive blaster.

Hi,I want to paint my car probably the only car i will paint what would be a good set up i have a 60 gallon 155psi max compressor and will install filter/dryer etc. about 75' from compressor. Thanks

Asked by: Pete
The shorter the air hose the better you'll be, unless you have a compressor which has a pretty high CFM output. Say your paint gun requires 6 CFM and you have 75 feet of hose. This would mean you would probably want approximately 12+ capable CFM output compressor to make sure you can account for loss in the long air hose.
