Improvement on durability for ambient
Reviewing the total cooling system including design of coolers and cooling fan with safety margin, the compressor can operate even under ambient temperature of 45¡C.
Improved maintainability
■Extended overhaul schedules
Recommended overhaul schedule of Air End (for both 1st and 2nd stage) was extended to 6 years. As for water cooled machine, maintainability of coolers also improved with easy cleaning construction.

■High-performance intake filter
A two-stage separation system (centrifugal separation and filtering separation with high dust collection efficiency) is adopted as a counter measure against dusty environments.
High performance screw unit
A completely new design of the two-stage compressor unit and a reduction in package internal pressure losses resulted in an energy saving by 8% over existing models.Furthermore, a plate-fin, the first in the industry, was incorporated for the water-cooled, inter cooler and after cooler, reducing the air pressure loss to 1/5.
Ultimate clean air
The oil-free design introduces absolutely no oil to the rotor chamber in the process. Stainless steel shaft-seal rings are used to prevent the generation of carbon dust, and KobelcoÕs patented twin atmospheric shaft vents prevent lubricating oil from contaminating the compression chamber even during extended periods of unloaded operations.
New type electronic monitor with liquid crystal display

Totally enclosed fan-cooled (TEFC) motor with enough capacity is selected to reduce the motor coil temperature and motor bearing temperature,leading significant improvement of reliability. Motor coil thermal detector is equipped for safety aspect.
Protection features
Various improved protection for Electric parts.
●Momentary interruption protection: Within 0.5 sec.
The compressor unit does not stop even when an momentary power failure (momentary power interruption, momentary power drop, temporary blackout) occurs, as long as the interruption time interval is less than the set value. The compressor unit is stopped when the power interruption duration exceeds the set value.

●Built-in 12,000-V lightning surge killer and noise filter.

●Automatic reset from power failure: 0.5 to 20 sec.
Example: Setting for recovery after power interruption: 5 sec.; power recovery standby time: 15 sec.
Using new type of refrigerant
R407C of no ozone destruction coefficient is used for all dryers.
Using new intake valves
To prevent oil contamination, air pressure is used for capacity control, instead of oil pressure.
Noise insulation material that is easily sorted for disposal
Materials are easily sorted for disposal, when disposing of the compressor unit (treated as industrial waste).
Reduction of pulse noise
A perforated panel silencer is adopted to reduce high-frequency noise (more then 1KHz,) and unconfortable noise.
Exhaust cleaner that requires no oil mist breather piping
Conventional countermeasure for oil mist is discharging the oil mist outside of package by using oil mist breather piping, which may cause the environmental problem. To avoid pollution,it was necessary to install filter on the end of piping or corona separation-type mist collector. Newly developed Exhaust Cleaner utilizes super fine filter which can be installed inside the compressor package, and no more breather piping is required.
This Exhaust Cleaner has its self oil separation and recovery function. This can prevent differential pressure increase and can realize long term maintenance interval.
