Essential air supply
To maintain this versatile output, Fabricon
Design operates an investment strategy of
continually upgrading to the latest developments
in CNC milling machines. But, to fully exploit
equipment capability, a reliable and adequate
supply of compressed air must always be
available as an integral part of the machines’
operation.
The air supply is required to operate the
clamps and valves on the CNC machines as well
as provide motive power for a battery of auto
saws. At the same time, compressed air is used
to control equipment temperature during dry
cutting procedures.
This air requirement became even more
critical when new production equipment was
installed. As Fabricon Design’s compliance savings with a 5-year payback from an upgrade
