Compressor question

[Hart_Rod]

Can Viar compressors be mounted in any position? TIA.

I was told yes.

I've always heard that yes they can. Jmedero, what is the reasoning behind the front of the comp facing the rear? I can't figure that out.

[jmedero]

I really have no idea. I was told it is for the air filtering to keep trash down to a minimum. I really don't buy it it was just what I was told.

mine is mounted sideways on the frame with no problems. been that way for a year.

How does the compressor know the front of the truck from the rear?

[tcb-1]

come on Shane, built in directional finder..... duh!

I read somewhere, probably here, that Viair recommends not to mount them upside down. however, many have done so without problem one.....

[jmedero]

nevermind. I was just saying what was told to me. I never said the comp had knowledge or could tell... nevermind
sorry Rob.

Mine is dead!! yep mounted it upside down I didin't think it mattered either..well I guess they dont like it......its less than 4 months old..the motor runs but doesn't build air....when I take my bed off and I take it off I'm going to do surgey on it and see if I can fix/rebuild it?? when I remount it I'm going to put it straight up???

From the horses mouth(Viair website)

Q: Is it possible to mount the compressor sideways? Must it be mounted with the cylinder upright?
A: Yes, you can mount our compressors in any direction or position because they are oil-less. The only position we do not recommend is upside
down, since heat tends to travel upward, and does not dissipate well in the motor housing of the compressor.

Q: If I mount my compressor sideways, is there anything I should be careful of when doing this?
A: If you mount your compressor sideways to the frame rail, you should periodically check to make sure that your compressor is mounted securely.
Use a thread-locking compound to keep the bolts from backing out and causing the compressor to fall off of the vehicle.

i had mine upside down for 3-4 years as a daily driver with no problems

I was just going to start a thread asking this question. Glad I used the search function.

may sound dumb but do you have a drain port? mine was doing that for a while and i couldnt figure it out, til i drained the tank lol

mine doesnt have a drain port, so one day i pushed a screwdriver in the schrader valve i have on my tank and it spit water out. after that, it built right up. i know, i need to get a drain port AND a water trap lol

i have had two 480's mounted upside down for 2 years now with zero problems, and i cycle the hell out of them. i dont think you will have a problem if you do mount them in this way. daniel.

[tech@scottshotrods]

i had (4) 450s mounted upside down on my dailey for 5 years no issues the dude that bought it is still rockin the orig compressors 10years later LOL
