Grasso 12 | 12E
Grasso 12E and Grasso 12 compressor series contain the world's largest number
of single-stage and two-stage compressors within one range.

The Grasso 12|12E and Grasso 10 series have
an unique welded steel crankcase that ensures
an extremely high heat dissipation, which allows
operation without cylinder head cooling and
oil cooling in most applications.
