 Topic: Regulator/Filter for Blasting Cabinet
Posted: 13 Mar 2020 at 5:03pm |
|
I'm overwhelmed by the options available for regulating pressure and removing moisture from the air going to a blasting cabinet. Is a combination regulator/filter OK to use or should there be two separate devices? For moisture control should it be a desiccant-type unit or a separator-type unit? Will two $20 devices do the trick or do I need to spend $100 to do the job? Any suggestions on what works for you will be appreciated.

I use a separator. Desiccant has to be changed out once the media becomes saturated. My pressure blaster came from the factory with just a separator and haven't hand any problems.

I added a dessicant/separator/regulator to my HF cabinet. The desiccant is small and did not last a session. I don't bother changing it any more. To date I've had no issues with moisture as set up and get the work cleaned and painted shortly after.
It was not an expensive setup

when the internet was young, I saw a site were a guy added a 'dehumdifer' rad between the compressor and tank to cool the hot air. there was some water trap/exit in there as well as a fan to cool the rad....pretty nice setup,probably still out 'there', somewhere.....

Mine has a small round moisture filter on it just like my spray painting guns. I get them at harbor freight or Menards. I've never had a problem with what little I have done.

My moisturizer trap is a 22” drive shaft off front of a 1980? Ford. I tapped one end for air hose tee. Put a old brass radiator spicket in other end for drain. That worked ok but I wanted fancier so had a buddy take it to his work. They cut it open put a tube that ran near the bottom for incoming air and 3 baffles, piece of metal full of small diameter holes for air to travel through to get to out port. I’ve not had any problem with moisture as long as I remember to drain it regular.

Not using a regulator or dryer, I use black beauty, no issues.

I have a small water separator in line after the tank. My compressor is inside the shop and I find in cold weather if I heat the shop first there is not much moisture in the system. I use mostly black beauty; pretty good stuff. Sometimes glass beads, depending on what is getting blasted. 2 cents worth.
