QuickAir 3 Woes

[adventureduo]

Maybe something's wrong here.... but our SMB we just bought came with a Quickair 3. Now, as far as i know they're supposed to be somewhat fast and pretty reliable. They've been on the market for quite some time.

Well, it took a good 10 mins to air up a 285/75R16 from 25lbs to 55 lbs. AND, it overheated and shut off after just 2 tires.

After cooling, i proceeded to air up the rest of the tires and it shut down again halfway through the last tire.

Coming from c02.. this is un-acceptable. Especially for a $399 compressor! Even my buddies crappy Costco compressor finished before us. Thank goodness we were airing up at camp and time didn't matter... since it took nearly 2 hours to air up! Just imagine a group of rigs waiting to head off down pavement and they're waiting for us!

This cant be right? Can it? I mean our tire size is tiny compared to what these compressors are supposed to be able to handle. And it says the runtime is 40 mins with 15 mins rest... i barely got 20-25 mins out of the thing.

The thing looks brand new.. the PO barely used it. I might call Sun Perf. tomorrow.. they're local to us. Maybe it needs to be looked at.

Any suggestions?


Compressor in question...

I had a Quick Air II for years and it was faster then that, but not by much. Cooling is everything. Can you get it out of the box when using it? That won't make it any faster, but might keep it from shutting down.

It's bolted into the box.. made that way from Sun. Made to run setup in the box. Shoot i know people that run the things under their hoods and they don't get that hot. I think there's something wrong with the unit... either that or a air leak i cant find making it take forever to air up and over heating the motor. I might just run it down to Sun this week since they're closeby.

Hey don't knock the Costco compressors, those things are bad ass! I just wish the head didn't have 3 sizes of fittings.

And then there is this thing.

I just had a 10lbs powertank on my last rig.. Why do you think im complaining? I was spoiled!

[daveb]

Yea a buddy has a 20 lb tank...kicks butt. There was a write up on compressors in… is it overland journal? My Extreme Air takes about 4 min per tire to go from 30 to 65 with 285/75 R16’s not counting the air tank that’s full. I would still like to find a spot for a CO2 tank.

Just got off the phone with Sun Perf. They said that what happened didn't sound normal to them and to bring it by. I will drop it off and let you know what transpires.

Just picked up the compressor from Sun. Spoke with Justin for a while. Real nice guy and real helpful. He showed me how they bench test.. and put our unit on it. Took the compressor up to 100 psi and shut it down. Inflated to 100psi in 29 seconds! ARB would take about 45 sec and VLair would take approx 35 seconds is what they said. This still did not tell me whether or not the unit will over heat next time out. However they put a new thermal shut down controller dealio in it.. and gave me a spare too. All for free. Real nice guys as i said before. I will report back after i test the unit in the next couple days.

It was neat touring the warehouse.. They showed me protoype Quickair4's and 5's (sorry no pics) . Here's a shipment going out to SMB West! THey ship out about 50 a month to them. Mostly quickair 2's. Some quickair3's. I guess SMB used to order hundreds a month. Times have changed we all know.

Was your vehicle engine running? The available current to run the compressor will make a difference, but at the same time, you may correspondingly find the compressor overheats that much faster.

Now to get that York compressor installed into my Bronco....
