Mid Feb 2019 I purchased an AirForce EPump. It arrived on Feb 22 and the details of my initial experiences are at https://www.airgunnation.com/topic/airforce-epump-overpriced-under-performing-but-runs-off-3-2amp-12v-dc/#post-449138
Total runtime is 12 Ninja w/EZ Valve fills from 3100 PSI to 4500 PSI at 1h 15m. 1 initial bottle fill from 0 PSI to 4500 PSI at 4hrs.
Fast forward to today -- About 30 minutes into the bottle fill from 3100 PSI I went to bleed the system as I normally do from AC power. The motor was stalled and there was a strong odor of overheating. The back of the motor was too warm to touch even with a squirrel cage fan pointed at it. Upon disassembly I noticed the gear guide collar was half way out preventing the system from fully cycling thus stalling the motor in the upward pump position. No fuses had blown. Upon switching the system to DC and using a deep cycle marine battery the 15 AMP fuses blew. Only the DC side appears to be fused, the AC side does not appear to be fused or the fuse system malfunctioned. There appears to be a thermal switch on the gear motor as well and this did not pop up/trip. On the AC side there appears to be some melting of wire between the AC plug connection and the red AC selector switch.
Attempting to tap the collar back into place results in it popping back out around 3100 PSI. There is a minor electrical burnt odor. There is a fairly strong odor of an overheated motor. The DC side now immediately pops fuses upon selection. The AC side will still pump up until 3500 PSI where the guide collar binds against the gear rod teeth.
I will contact the AirForce service department tomorrow and keep this thread updated with the experiences. As it stands now I am unable to fill the bottle.
