Post by: Darkspeed on September 14, 2015, 11:16:23 AM
What is the currently preferred Air Dryer if installing from scratch? AD-IS? AD9?

Thank you!

The only advantage to using a current day air dryer is most now have spin on desiccant cartridges. Makes servicing your air dryer a ton easier, but more expensive. However the cartridge doesn't have to replaced that often. Most here will not be putting on >5000 miles a year but there are a few.

I put the IS with the spin cartridge on this year.  Only reason was for availability and ease of changing the catridge.  Weve put 5-10k on the bus a year for the past two years.

I think I paid about 250 new.

does anyone have a pressure regulator/check valve before their air dryer?

I'm curious!

No but you see a lot of Transit buses that had the air starter with a fast fill valve there it was a regulator/check valve

perfect as i've removed mine.. I never use the fast fill so i'm happy..

the one installed was some horrible Webco that costs $400 and with no PSI setting I was having to guess the air flow!
