I am passing on this info in hopes that it will help someone who's air
suspension needs work.
Those who are looking to update the air suspension may wish to consider a
Thomas air compressor, model 317 or 315.
Last fall I started searching for a replacement for my tired old Dana, which
took more than a minute to pump from 0 psi to 120psi (wouldn't do it at all
at ambient air temperatures of below 30 degrees.)
I discovered that Thomas makes two that were possibilities: Model
317cdc56/12 (rated to 150psi) and 315cdc45/12 (130psi).
In December I installed the 317 model. Fits in the same space as the O.E.
Dana, MUCH quieter, and pressurizes my air tank from 0 psi to
120 psi in under 10 seconds. Cycling from 100 psi to 120 psi takes 4
seconds.
One other note.... It probably could be wired into the O.E. wiring harness,
as it draws a maximum of 18 amps after start-up transient, but since it is a
long run from under the kitchen module, where the compressor sits in my
coach, to the O.E. 35 amp breaker behind the glovebox, I installed a relay
protected by a 30 amp slow-blow fuse instead.
Now that I have installed the 317, I think the 315 would also suffice and
provide a cost savings. I paid $200 for the 317 and could have bought the
315 for $165. My local distributor indicated that in repeat order quantities
of 3+ the 315 would be $132 each.
Specs are here on the Thomas web site:
http://www.thomaspumps.com/pdf/317.pdf and
http://www.thomaspumps.com/pdf/315.pdf
I would post a picture of the installation but I do not own a digital
camera.
