PERFORMANCE!
WEIGHT! SIZE!
(as opposed to two shafts connected with a coupler) By so doing, compressors can be run faster, providing higher performance without fear of overtaxing a rubber drive belt. Ah, but now enter Air Line Direct-Drive Hookah

Prior to The Air
Line's
introduction of surface supplied air, the only technology available was
compressor systems powered by motors through rubber drive belts and iron
pulleys; not terribly efficient especially in wet, marine environments.
They had to be run somewhat slowly to prevent slippage and belt erosion.
Slower running equated to reduced air volume. Because the compressors
and motors were separate, the systems tended to be large and bulky. The
iron pulleys on the larger units added as much as 15 lbs. to the overall
weight. Incredibly, this technology dated back to the early 1900's.
Direct-drive is just that: a compressor mounted directly onto a motor
shaft.
