Mositure in air tanks

<< < (2/3) > >>

Arden Smith:
I look and look, I see air filter for engine, compressor and powersteering pump, air tank,  powersystem(tank and pump) for leveling, batteries, starter, etc but I still can't find the dessicant and coelessing (sp) filters. Maybe I am just blind or need new glasses. Would this be mounted anywhere on the compressor or close to the airtank. What airlines should I follow to find it, Is it between the compressor and tank, discharge of the compressor, Where? Or what does it look like?

Gerald Farris:
I think that most of our coaches run a Meritor dryer and a picture of one can be found at
http://www.anythingtruck.com/Merchant2/merchant.mv?Screen=PROD&Category_Code=HTP-AIRDRY&Product_Code=650-R955205

This is a decription of the way it works, and it should be located between the compressor and air tank.

A Typical Meritor WABCO Air Dryer Cycle:
1.The governor turns the compressor on when supply tank pressure drops below cut-in pressure (approximately 100 psi).
2.Compressed air travels into the air dryer at the inlet port:
◦Moisture-rich air and contaminants travel into the desiccant cartridge.
◦The moisture and contaminants are retained by desiccant; moisture also collects in the base of the dryer.
3.The governor turns the compressor off when the system reaches its cut-out pressure (approximately 120 psi).
4.The purge valve opens when the governor tells the compressor to unload:
◦The air dryer purges, expelling water that has collected in the dryer base.
◦Then the regeneration valve opens:
■Dry system air flows back through the dryer. 10 psi is taken from supply and secondary tanks.
■This back flow dries the desiccant, preparing it for the next cycle

Arden Smith:
Is it possible that my rig doesn't have a air dryer because it doesn't have air brakes just air suspension??? I looked at the web site for merit and for haldex and seen pictures of these units and I sure haven't found anything that looks like that yet.  But I will go look again. I will remove the intake air filter to the engine so I can get in there better.

Joel Ashley:
Don't know if this will help, given the difference in coaches, but the dryer on our '06 Monterey is sitting large and obvious as the very rearmost of any component on the coach on the passenger side, just inside the rear bay door.  Though not precisely the same label as on the one shown at the website Gerald gave you, it otherwise looks the same.  It isn't a small device, and has large and small hoses coming and going from it, so it shouldn't be able to hide from you too well.

Mike And Mary Engen:
Don't know if this helps, but on the 95 it is in the back of the coach, you can see it in the back of the battery compartment, it looks like a large oil filter. Mine is a Haldex.
