Aspen 1.9cc Compressor Dissected

The Aspen compressors are miniature rolling piston rotary DC Inverter refrigeration compressors (see image below courtesy of Thermaltake for how the internal stuff works). This is also the same basic principle and implementation used in the RIGID Tiny compressor I purchased as a replacement for the Aspen that met an early grave at my hands.

I figured since I blew up my Aspen (p/n 19-24-1101), I may as well take it apart and see what makes it tick (click image to enlarge).

Pretty cool design!

Stay tuned for exciting news about my tests with the RIGID compressor.

In addition to the current, it's totally quiet; thus, you do not noise to your neighbors if you would like to use it inside.

While it's the higher than benefits, its main flaw is that it does not go together with a roll cage; thus, you wish to be terribly careful once transporting it. The unit is just ideal for little jobs; thus, if you're inquisitive about associate degree industrial unit, you must look in different places.
