Air pressure relieve and dust in air filter

[jerry davis]

I noticed that while parked on any dirty road or just plain dirt area with the engine running, a large cloud of dust would appear every time the compressed air relief valve opened.
Since this area is right below the air intake I was concerned about the engine taking in excess dust, not to mention how dirty the coach got.
To solve the problem I ran a 3/4" hose from the air release valve out to between the rear mud flap and back bumper. This really helped.
Has anyone else had this problem and is this an acceptable solution?

AS long as the hose doesn't run uphill you should be fine. That "burst" comes from the air dryer and is triggered by the air comprssor governor. It is used to eject any moisture that has settled into the bowl of the air dryer. If you ran the hose uphill, or had a sag in it, it could fill up with moisture and freeze up in cold weather. Other than that, the hose won't hurt anything.
