The valve is a positive-closing disc type with orifices, using spring and air pressure to activate.

Kobelco KNW Series Oil-Free Rotary Screw Air Compressors

Required settings for pressure control, temperature alarms, and control time delays are viewable and may be modified using the touch screen. The input bull gear is supported on each side. Pilot lights, viewable from a distance, are provided for indication of operating conditions.

Shells are made of carbon or optional stainless steel with an ASME stamp. The compressor will not operate until oil pressure is established. A lunch stop is made in the popular Hood River area.

Product Information | Kobelco KNW Series

Highly Efficient Cooling System. This course is designed for KNW compressor service personnel who are responsible for maintenance and equipment repair. VFD control becomes less energy efficient compared to fixed speed when operated at the upper end of speed range.

Kobelco KNW Series water-cooled models feature highly efficient, removable, copper tube bundles. Universal Module for communication with facility management system. This design includes a patented, high-efficiency super rotor profile and cooling jackets. Air-cooled heat exchangers are made of heavy-duty aluminum with a special coating and are designed for all published operating conditions.


Thrust balance pistons on each stage provide maximum air end life. Copper tubes with internal turbulators. Air Filter Element with pre-filter. This reduces the overall energy cost significantly.

Kobelco KNW SeriesĀ®

Standard air cooled kobelxo exchangers. All oil-side piping is stainless steel and has SAE leak-free fittings. Internal turbulators provide optimum heat transfer with minimal pressure drop. Competitors use a lip seal design, which is prone to wear and leakage. Push buttons are provided for specific control functions, allowing continued compressor operation in the event that the terminal is off-line.

Held Sunday from 8: Heavy Duty Air End Design. The stainless steel, non wearing air and oil seals with dual vents to atmosphere, assure oil-free air. The heavy-duty air end design has proven itself consistently since around the world in demanding applications.

These files can then be opened using Microsoft Excel. These features are not found on competitive models. Unloaded horsepower is guaranteed and repeatable. Lubrication prior to start up, during operation and shutdown is supplied by an independent iobelco gear pump. A universal communication module is onw available to handle virtually any Ethernet or Serial driver.

Leak-Free Fittings on Oil Circuit. Water-cooled models include a kobeco valve on the intercooler and an automatic shut-off valve on the cooling water inlet. Independent Motor-Driven Oil Pump. Messages are sent to direct the operator for service, pre-alarms, and alarms, and will be shown when necessary.


Owner Maintenance and Service Training. Competitors use carbon rings with single vents and no thrust balance. You Will Learn To: A filter change notice is indicated on the HMI.
