Air Filter Element with pre-filter.

Thrust balance pistons on each stage provide maximum air end life. Required settings for pressure control, temperature alarms, and control time delays are viewable and may be modified using the touch screen. Leak-Free Fittings on Oil Circuit. This finish is chip and corrosion resistant and keeps the compressor looking new throughout its lifetime. Oil Filter with Differential Indicator. Both provide the ability to download data loggers, alarm history, compressor status report, and the daily report from the HMI.

Also included is an SD memory card. An audible alarm is provided for alarm annunciation. VFD control provides a narrow system pressure band, reduces inrush at start-up, and allows more frequent stops and starts. The valve is a positive-closing disc type with orifices, using spring and air pressure to activate. Kobelco KNW Series air-cooled models include a thermostatic mixing valve to insure proper oil temperature in changing ambient temperatures.


Water-cooled models include a thermostatic valve on the intercooler and an automatic shut-off valve kobrlco the cooling water inlet. The design increases gear and bearing life and is not offered on competitive models.

Air, Oil and Water Flow Circuits. A filter change notice is indicated on the HMI. These features are not found on competitive models.

Operations include controlled sequential starting and stopping, pressure control, and protection from conditions that could damage the compressor. Internal turbulators provide optimum heat transfer with minimal pressure drop.

The inlet air filter is easily accessible and includes a cleanable prefilter which extends element life.

Messages are sent to direct the operator for service, pre-alarms, and alarms, and will be shown when necessary. State of the art IO-Link Communication.

Sign up for our newsletter! The HMI terminal shows operating conditions, pressures and temperatures. Real lobelco pressure and temperature values are displayed on the HMI. Unloaded horsepower is guaranteed and repeatable. Lubrication prior to start up, during operation and shutdown is supplied by kibelco independent motor-driven gear pump. A universal communication module is also available to handle virtually any Ethernet or Serial driver.

This reduces the overall energy cost significantly.

Kobelco KNW SeriesĀ®

Air-cooled heat exchangers are made of heavy-duty aluminum with a special kbelco and are designed for all published operating conditions. We recommend compressor service personnel who have 6 months to 1 year of experience with the Kobelco KNW Series compressors. Competitors use carbon rings with single vents and no thrust balance. Rotors, shafts and compression housing have a PTFE coating for corrosion and wear resistance.
