Advantages

Compact design:

The G-BH is about half as large (installed volume) and nearly 60% lighter than a comparable standard machine with the same performance characteristics. 

Quiet:
Modern sound engineering: only half as loud (78 db(A) versus 84 db(A))

Economical:
Cuts costs for: shipping (low weight), packaging (smaller), electrical installation (smaller cross sections and smaller circuit protection devices), electrical energy (high efficiency and good controllability)

Flexible:
These units are normally operated with frequency converters. The housing components can be rotated in 45° increments without manifolds and silencers or in 90° increments with manifolds and silencers. Together, both of these features offer maximum flexibility upon integration in the overall system.
