The EL 2 GM compressors used a dessicant/dryer/ mini air tank. More like a
pulse chamber, than a tank, all it did was smooth out the air that
exhausted from the compressor. The dessicant feature trapped and evaporated
the moisture concentrated when air is compressed. They were a sealed up
unit attached to each compressor. The compressors were a permanent magnet
type DC electric motor, and therin was their downfall. The Alnico magnets
eventually lost their magnetism, and the motors lost power. (They were
never supposed to last 40 years). Answer? Use modern Rare Earth Magnets
like ViAir uses in their compressors. Even if they used crap magnets, they
should not be a problem for many of us. (Grin) Most of the ViAir
compressors only differ in the type of external finish, or carrying handle
configuration. They pretty much all will outperform what GM used. Once in a
while we get a great product from offshore manufacturers. These things are
not cheap. But, they are very high quality.
