The small leveling compressor does not fill the coach tanks. You have your controll level panel on and every so often it will add or subtract air from bags to level. Everything is working as it should.

There are a couple of advantages to switching to a higher volume compressor, one is obvious, i.e., takes less time to level thus compressor runs for a shorter period of time and the 2nd advantage is that you can use the Viair to air up your tires rather than using the engine compressor to do that. The downside is that the higher capacity Viair compressors pull more current requiring a new 12 volt supply (10 gauge wire vs the current 12 gauge wire and a higher amperage fuse). The cost to do that is minimal especially considering that the Viair compressor is about half the price of the Thomas compressor.

I know he said tanks but I thought he was saying the coach didn't relevel when the compressor ran.

I replaced my compressor with the ViAir compressor as well. I ran into a problem that you may want to consider. I opted for the continuous duty 120 psi compressor, figuring the 120psi would be the best option, but what happens is on excessive slopes, when the coach would normally stop running the compressor and display the error, the compressor beats the error to the punch and with 120psi of pressure in the lines starts popping the pressure safety valve, which is very annoying to your neighbors. Psst, psst, psst..... Especially if you've left for the afternoon with leveling on.

I am not sure how much pressure it takes to fill the air bags but I expect it is something like 50psi. So in my case I should have purchased a lower psi unit, which I plan on doing soon. Unless someone can convince me otherwise.

Bob,

I had planned to use existing plumbing and just hook the Viair exhaust directly into air drier input with existing HWH controlled solenoid but with beefed up wiring for the increased amperage in the Viair. I will definitely check on the issue to which you have alerted me.

I have a couple of questions,

1) Did you power it using the HWH solenoid which is controlled by the existing pressure switch which I believe is an 85/105 switch?

2) is the pressure safety valve which is popping one you added or is that built into the Viair compressor?

3) which model compressor do you have?

Thanks

Ray

450C-IG Compressor Kit
150 PSI / 1.66 CFM
12-Volt
Duty Cycle: 100% @ 100 PSI
Max. Working Pressure: 150 PSI
Max. Air Tank Size: 5.0 Gallon
Max. Amp Draw: 23 Amps
Ingress Protection Rating: IP67
11.25"L x 4"W x 6.75"H
10.4 lbs

I used existing wire from the hwh

The pressure valve is on a metal plate that also holds a couple selenoids, the plate also has the connector that connects to the hose from the compressor, i believe it also has the power connection to the compressor coming from it as well.

I don't believe the pressure switch has any type of electronic connection, maybe it does on earlier models, but mine just pops over and over. When I was looking at changing mine out, I was told this....

My auxiliary air compressor could not consistently level my coach. I replaced the Thomas with a Viair 330CIG. The Viair is a continuous duty pump and the specs show about 3 times the capacity at 100 psi and still draws no more than 12 amps. The Thomas pump draws a max of 10.5 amps

I almost never hear my auxiliary compressor (Thomas) activate. Is it that quite and if not how do I test/confirm it is operating properly. I have to relevel by cranking the engine. Sounds like I am heading down the same road as some of you.

You should hear it trying to level, not sure you will actually the compressor itself but you will hear the sounds of air leveling.

In checking the motor on my compressor I connected 12 volts directly to the motor and nothing happened so that is one way to check it for operation.

If replacement is needed what is the downside of going with the exact Thomas compressor besides slower relevel.

Mine is below and too the left of the steering wheel, I have two fuse panels, it is circuit 265, a 20 amp fuse in the bottom fuse box.

The other advantage of a higher volume compressor is you will have higher volume of air to air up tires if you wanted to add a connector for that.

I just replaced my Thomas compressor with a Vlair this past weekend. The Thomas was turning on but not moving any air. Works great now. So far so good.
