12v Compressor
« on: February 19, 2018, 07:36:42 AM »

I'm thinking of abandoning my York OBA set up.  It works and it's great, but it's also been somewhat of a pain in my ass.  My serpentine belt squeals pretty much every time I start up the Jeep, I'm thinking because I put the York in place of the idler and have extremely limited tightening ability.  Anyhow, long and short of it is I was thinking I'd go back to the stock belt configuration, build an offset mount for the York, get a v-belt clutch and a serp/v-belt pulley for the alternator.  Then I started looking at 12v compressors and I can get one for the same ball park and just dump the York.  So.....

Anyone have any experience with Airmaxx compressors?  They're about half the price of a Viair, but I don't want to spend money twice.

https://www.amazon.com/airmaxxx-Ride-Suspension-Compressor-chrome/dp/B00BEN3BNU/ref=sr_1_5?ie=UTF8&qid=1519053396&sr=8-5&keywords=airmaxxx+480

VS.

https://www.amazon.com/Viair-48043-Chrome-480C-Compressor/dp/B000FQ95J6/ref=sr_1_2?ie=UTF8&qid=1519053131&sr=8-2&keywords=viair+480

At that price, I could get two and run dual compressors and likely wouldn't notice much difference vs the York.  (Or just run one)

What say you?

Following,  not much can keep up with the York. I ran the large ci one on my 5.7. When I switched to the LS, I pretty much ran out of room in the engine compartment,  so I ditched it and went to a 10 lb C02.  The bottle is fast, it's also costly and time consuming to fill.  I have been looking for a reasonably inexpensive 12 volt compressor to replace it. I've wheeled with a few that had the 400 Viair and on big tires it's a pretty good  wait to get them 10 lbs higher.

Doug had the old Viair 550 and it's only slightly slower, probably less than a couple minutes total time, but he's also filling 35's and I'm on 37's.  I don't mind a little slower but I also don't wanna be at the end of a trail all damn day either.

I like the York for sure, I just hate fighting this belt squeal and really don't wanna mess with building a bracket that will line up etc etc.

Getting lazy in your old age? I know how it feels. :high5:

While looking around your links on Amazon, I found this one:

https://www.amazon.com/Viair-40040-400C-Air-Compressor/dp/B000FQ78TU/ref=cm_cr_arp_d_product_top?ie=UTF8

I'm not sure what this part means "2.54 CFM Free Flow @ 0 PSI". Usually the CFM is just given by itself. But if it is just like the other CFM's, then it's like 40% higher than the others. It also has a better review rating than the airmaxx. Also it's not chrome. They all do look like they came off the same Chinese assembly line though. :biggrin:

I'm not condoning Smittybilt, but for comparison this one has a higher CFM.

https://www.quadratec.com/products/92043_8005_07.htm

It says it has 72 Liters Per Minute. Which converts to 2.54 CFM.

I have a NIB 480c. My son and New Jim expressed interest in it. Don't buy one yet. I found a rebuild kit for my 550c so don't need it.
This can be had for $94 Amazon Deals (3.5CFM claim)

Yeah, that one's confusing because it says 3.5 cfm in the description and then at the bottom in the specs it says 1.38.  If they aren't gonna take it let me know.

Duty cycle I figure is as important as output, don't wanna be three tires in and have to wait a half hour.

Yeah, that's odd. Wonder if they are giving specs for two different compressors. Check Jeg's or the manufacturers website for info. I will see if mine is available. I didn't want to pay return shipping and restocking fee so I kept it. Doug's Deals  :thumbsup:

Don't know, I've never looked at a HF one.  I want to make sure it's money spent once is all.

this one looks ineresting for the price
$52  2.54 CFM.... Max Pressure 150 lbs.
https://www.amazon.com/Master-Flow-MF-1050-MasterFlow-Compressor/dp/B000L9AD2U/ref=sr_1_5/145-5045500-8330818?ie=UTF8&qid=1519105272&sr=8-5&keywords=12v+high+volume+air+compressor

That's the same one I bought like 11 years ago. It still actually works, but I need to do a rebuild on it. The newer ones out there look like they blow it away though.

I'm leaning toward "Doug's Deals" unless he's got a buyer already.  Although my next conundrum is where to mount it, maybe I need to move my tank to the underside.

That is the one I have. It actually works great! Only I have not hard wired it anywhere so I have to hook it up to battery via clamps, which is little bit of a hassle. But not too bad and the hose will reach all the way around the Jeep so I do not have to move the pump. Not sure what the duty cycle is, (which is also very important) but it doesn't slow down at all doing all four tires. A couple years ago wheeling with Will @ Moab, he had the ARB compressor and I had this one and it was purdy much neck and neck filling our tires. His was just a tad faster b/c I had the 37's and he had 35's.
Going from 10psi up to about 25psi takes less than 2 min a tire

I'd like to get a different one for the new truck... so those Amazon deals aren't looking too bad.

Ben... why down on Smittybuilt? All these things are made in China anyway.  :shaking:
Also, I believe the CFM @ 0 means if the hose were not connected and the pump was just free blowing, that would be the amount of CFM it produces. But that is just an edumakated guess.  :cheers2:

I have this one.  It does the job well.  The guage that came with it is not the best so I have another.  I found it for sale for just under a hundred at 4wheel parts.
