NEW Daystate Compressor – 4500 PSI, 110v, Quiet, Clean, Portable!

I’ve owned an LC-110 for 8 months and am 100% satisfied. However, the original unit AofA sent me was delivered with the label side facing down and no other markings on the carton to indicate “This side up”. I didn’t realize this until I opened the carton and realized the compressor was upside down. Nothing appeared damaged until I powered it on and t the motor just hummed but was locked up. The fan on the compressor wouldn’t turn when I tried to spin it manually. Upon closer inspection the fan cage was bent although it wasn’t blocking the fan blades from turning. I fault UPS for the careless handling and damage. AofA immediately sent me a return label and sent a replacement the day it was picked up for return. The second carton was labeled with arrows and the replacement is a great compressor with zero issues.

I've got a FLIR thermal camera if you wanted some thermal images and are curious. As I understand it's not so much a heat condition as it is running it without compression to blow out any accumulation of moisture. There's a few threads on this being good operating practice to ensure latent moisture doesn't cause any issues.

Always wanted a Flir, and would be interested in temp readings. I am going to order a temperature gun like this one:

Rereading the instructions you posted:

#5 Finally, start the compressor and let it run for another 2-3 minutes without building pressure to cool down and remove any leftover condensation from the unit.

Since it only takes seconds to purge the unit of moisture, I believe this addendum was more for cooling than moisture removal.

See https://www.airgunnation.com/topic/daystate-lc-110-thermal-images-warning-large-number-of-images/ I did not see any build up of heat after the unit powered off via auto-stop, actually the opposite, as the heat sinks did their thing. Hope this helps and cheers -- I really do think it's to purge any build-up of water but that's just my thoughts.

I would not expect the unit to keep building heat after shut off. FWIW, my mechanic told me that when your brakes are hot, coming to a complete stop is when the damage occurs, he recommended if you find yourself in that situation it is better to slow down but keep rolling if you can until the brakes cool down. I relate this to the compressor shutting down hot, but I could be wrong, and have zero knowledge how hot is too hot. Peace

After dorking with the FLIR camera I'm inclined to think it's "both" -- cool it down and blow out the moisture, like the manual said. I think you're correct.

@JWilson - that is one of my suspicions. There's some wobble to the unit as a whole, vibration and rattling. It's also drawing about 1.2A more than the previous unit.

The cage shroud over my fan was also bent a little, although there were "This side up" stickers on the box. I brought this up to AoA and said the difference between this one and the other was that the first one was FedEx 2nd Day Air and this one was UPS 3-day, and I know UPS to be not so gentle with fragile shipments. They dismissed any notion of it being damaged in transit, but (1) it was bent up a little (2) it seized up until I took the belt cage off.

The other mystery here with mine is the gauge on the compressor. My tank's fill gauge is very accurate. When my tank reads 3900psi, the compressor gauge reads 3600. When my tank reads 4400, the compressor reads 4200. I filled my bottle to 4550 before I realized the compressor gauge was off.

Since it only takes seconds to purge the unit of moisture, I believe this addendum was more for cooling than moisture removal.

Purging only blows out water accumulated in the moisture trap but there are still some water distributed in the cylinder and tubes so I think the purpose of running it unloaded is to remove those residuals of water in the system. I saw the presence of water drops in the cylinder when I pulled my Yong Heng apart recently so I have adopted the same pre-shut-down procedure since then.
