(Feb. 2022) I bought the "TXEDT032" Dec. 24th, 2021 on Amazon with a 4-year warranty and I have been using it for multiple PCP Air guns & (Two) 45 minute (68 cu ft ?) 4500 PSI SCBA tanks. The unit has about 2 HOURS +/- run time on it so far, which consists of the following usage:
A 10 min. test run after setup, 3 total top-offs of the SCBA tank(s), and a single EMPTY to FULL fill of an SCBA tank (all 4300 PSI fills).
DETAILS: (2) top-offs of a re-certified circa 2012 SCBA tank from approx. 3100-4300 PSI each time (approx. 25 min. +/- total), (1) top-off (same tank) from about 2800-4300 PSI (approx. 15 min. total), and a single complete fill on a different re-certified circa 2016 SCBA from 0-4300 PSI (approx. 60 min. +/- total) with no issues to mention.
NOTE: On the 0-4300 PSI fill, I stopped at 2500 PSI and let the compressor rest (Cooling system running) for 15-20 min., then continued to the 4300 PSI total fill.
All fill times were done outside in 45F - 48F degrees for the top-offs and about 43F +/- degrees for the EMPTY to FULL 4300 PSI fill. Hope this input helps!
UPDATE 5/30/2022
I now have used the compressor for over 5 hours. At the 5 hour mark I changed the oil for the 1st time (which is quite easy!). I'm using "Royal Purple" Synthetic oil ("Synfilm Recip. 100") - Reciprocating Air Compressor Oil. The Tuxing TXEDT032 compressor has been a great investment so far and the product seems to be of above average quality.
