1. Above specification can be changed without advance notice for improvement of performance.
2. Outlet amount of air is value converting to inlet condition.

Structure and Characteristic

	Structural Design for Maintenance There are Arranged inside Compressor for Replace Convenience of each Expendable Parts.
	Fixed by Steel Pipe and Flange Connection with High Durability for Assembly and Disassembly There used Steel Pipe for Air Piping and Oil Piping to Increase Durability, and used Flange Joint to for Convenient Assemble and Disassembly.

High Durability Oil Level Gauge for Simple Identification

There are Mounted Oil Level Gauge that is used Bearable Special Material Against Pressure to 20kg/cm2 so that always can use Permanently in Clean State.

New Technology Application

Maximization of Oil Separation

Secured Space that can Absorb Shock Separator Element Flow-through Velocity in Separator Tank by making up for usual Oil Separation System. It Reduced Preservation Maintenance Charges by Maximum Extension of Life-time of Separator Element and Minimized oil in Outlet Air by Minimizing Changing Velocity of Flow.

New Unloading System

It is Adopted Unloading System that can Minimize Power Requirement when Operating with Non-step for Loading Amount Control at Loading Operation and Discharge Pressure Purge at no-load. Cooling Effect is Enlarged and Compressor becomes more Compact by Adopting new Material Heat Exchanger. (Hydro-cooling System).

High Effective Screw Rotor

It is Applied High Effective Key Screw Rotor that gets Born from Combination of Modern Manufacturing Technique Power with Computer Design of new Concept by long Experience. This Key Type is Consisted of Lobe Medical Charge 4:5 with the Shortest Seal Line and having the Less Leakage. This Key Type Minimized blow Hole, and Reducing Torque Requirement, can Produce Lots of Capacity under same Power. As a Result, it Display the highest Efficiency by few Leakage and the Lowest Power Consumption.
