Advantages

Compact design
The G-BH8 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.

Regarding IE3
200 Hz motors which are used in this side channel blower do not fall under IE regulations.
