Johnston Press has installed two
Boge SLF 75 frequency controlled
screw compressors along with a Boge
S 75 screw compressor.

The Boge SLF combines a coupled
drive system with frequency control
to provide a compressor for pressure
control under variable output
requirements. It is a low carbon
technology that works in accordance
with the compressed air demand by
producing the exact volume of
compressed air at the pressure
required. Frequency control
minimises idling time and helps even
out air demand fluctuations.
