NAPA 12-Volt Dual Air Compressor (MT-WM102-15C)

[Stephen]

I was able to do a quick test of my new napa compressor, on my 01 f250 7.3l on the front tire sized 35x12.5r17, I deflated the pressure to 10 psi, and then hooked up the compressor turned it on and it was able to inflate the tire to 50 psi in 2 minutes 2 seconds. I like the nice long hose that it comes with but will be upgrading the power wires as the ones that come with it got a bit warm while using. It is a bit large for a tire compressor but it is well worth the size for the performance.

side note, when I was talking to a buddy at work he was telling me how great is compressor was, he said it was a thor compressor... he paid around $200 for it and has had it for a couple years. https://thorslightningairsystems.com/products/thors-lightning-bolt-true-dual-air-compressor


they have a wide variety of mounts for their air compressor, see them here https://thorslightningairsystems.com/collections/refuge-compressor-mounts

looks to be the same design as the napa.

Rotbox needs to pick one of these up!

Yeah, the Thor's Lighting ones are the same, as well as the King's Thumper II's down in OZ, and a dozen other ones out there. They probably all come out of one big plant in China with a different color of paint on them for each brand.

OK, finally getting this finished in advance of the RME Moab Trip next weekend.
Just did a two tire test from 15psi to 50psi: 3:50



Thats compared to 2:05 for one tire. That's pretty good! Now its time to build the four tire hose setup and test that!

 

[Stephen]

OK, four tires from 15psi to 50psi takes 8:16! That is awesome.

That's almost exactly what @Maverick did last week coming off Black Dragon Canyon with his 4 tire setup. I think he was that number starting when he got out of the truck to when he'd put the compressor away. He's only going to 30 psi or so if I remember correctly. I still owe him a time for single hose, ARB Dual compressor. 17 psi tires to 30 psi tire time.

With my ARB Single setup, it was taking me 30 minutes to do all four tires. So being able to do all four in under 10, that's a huge time savings.

Thanks for the report! I haven't modded mine at all yet but, nice to see the capability.

Here is the Amazon parts list of what I've used:

Silicone Lubricating Grease
300A 4 terminal relay
70psi-100psi Pressure Switch
Hi-Flo Quick Connect Fittings
175A Anderson Connectors

I got the 4 AWG wire by cutting up a set of jumper cables from O'Reilly and the power switch and mount I grabbed at Marshall's Industrial Hardware.

I've seen a guy add a pressure relief valve to the manifold, but don't see anyone else adding it. In your opinion, is the pressure relief valve necessary? link below:

Also I've seen a check valve attached to the manifold before the Hi-Flo quick connect. Is this also necessary? Link below:

Thank you

I don't know why this would be necessary. I guess if you want to release the pressure in the line before you disconnect them? Seems like overkill to me, though.

Again, I'm not sure why you would need something like that.

The safety of the pressure relief valve sounds like a smart addition to me in case there is an issue with the pressure switch (i.e. the compressor won't shut off). Better to pop a relief valve than to burst a tank or a hose...

 

[gijohn40]

I have the ARB Dual compressor in my Jeep and made a high flow set up which is overkill due to the valve stems being the stopper.
I have #6 wire from the battery to the compressor so high amp.
I went from 13 pounds up to 38 on my 37x12.50x17 tires all 4 at once.

 

[Khrissicks]

Would a 1/8" to 1/4" adapter from the manifold to 1/4" NPT high flow have similar air flow? To avoiding tapping to 1/4"...

I used mine on the BDR trip and I’m super impressed with the compressor. The gauge and the bag sucks, though.

Anybody put theirs in a dedicated toolbox?

Not yet. I ripped the zipper on the factory bag my last outing, so I'm gonna need to find a better solution.

Mine ripped at the handle and started a few holes from vibration abrasion. I guess 2,400 miles is more than the bag is rated for. 😆

I have been contemplating getting one of these and modding it and putting it in a Milwaukee pack out.

They’re heavy, but seriously impressed me.

What is the cfm on the NAPA compressor? I came across this one and was curious if it was worth the extra money?

10.6CFM. From what it looks like, the one you posted has a purge valve and a fancier air line, otherwise its the same.

I'm seriously considering buying another NAPA air compressor to use with my C10 and the bagged suspension. The air bag kit that I'm installing came with a Viair 444C which puts out a measly 2.12 CFM with a 100% duty cycle at 100 PSI and 50% at 200 PSI. The Viair has a max draw of 23 Amps. Looks like the NAPA compressor cranks out 10.9 CFM (as @Stephen just mentioned) and it maxes out at 150 PSI and draws a massive 90 Amps max... more power, for more air!

The NAPA Compressor is obviously going to be larger physically, but I'll manage if it'll raise the truck at a much quicker rate. I don't know that I need 200 PSI max like the Viair is capable of, but I'd like to think 150 Max is plenty?

The air bag kit included a 2.5 gallon air tank, but with 5x more air I feel like the tank and bags will air up so much quicker which would be awesome when I need to get it off the ground.
