· Human-friendly space arrangement

By maximizing the convenience of maintenance by assembling friendly components and applying a hinged door, the maintenance time has been reduced, and the conversion type oil filter that has minimized bolts has been improved and the oil filter O-ring has been applied. replacement of parts is minimized and the convenience of cleaning the cooler is added. We guarantee the safety and convenience of product cleanliness to our customers at all times.

· Energy saving

The rotor of SCREW Airend, a newly developed product, is a world-class product optimized for the space of construction through precise processing.
- Configuration of 1:1 rotation speed ratio between motor and rotor
- Designed based on the rotation efficiency of Male Rotor & Female Rotor
- Energy saving through application of high-efficiency suction valve

· Low noise

Airend is specially designed to suppress noise generation, and the low-rotation fan motor reduces the noise caused by air friction through the simulation of the air flow of the silencer and fan motor. Noise is suppressed with a high-precision silencer. We succeeded in suppressing noise with specially designed venting valve.

· Air Filter

Air filter prevent infiltration of dust and impurity to the rotor, and it secure lubrication oil from contamination, thus it play an important role for smooth operation of compressing system, i.e., it directly affects to lubricating oil, air end, oil-air separator, and electromagnetic valve. Because fine dust is invisible, when inferior and cheap filter element is used then very small particles of dust accumulated in the room of air compressing system rapidly, as the result it occurs severe damage of rotating parts. BUMATEC has applied filter element with two-stage processed high quality material to ensure clean air intake.

· Energy Saving 1:1 Direct Driving with Soft Coupling

There is a set of soft coupling between electric motor and air end for efficient power transmission of driving. The coupling is reliable, and has the function of smooth connection of motor axis and air end axis, and reduces the shock load caused by starting torque.

· Convenient Maintenance of Belt Transmission

BUMATEC’s another design is application of belt driven air compressor for low power model. The advantages of these models are easy adjusting of compressing pressure and overload protection. Seal of shaft can be simply replaced, thus it reduces maintenance time and cost.

· 3 Steps of Oil and Gas Separation System

Step 1 : It is gravity separation by vortex wind flow in the separator tank.
Step 2 : Air and oil are separated by hitting on the bottom part of separator wall.
Step 3 : As compressed air is going through ultra-fine filter element, it can be obtained clean air that the oil content is

to be less than 2 PPM.

· Lubrication Oil

BUMACOMPRESSOR has applied ‘Super Cooling Oil’ for lubrication of air compressing system. The advantages of super cooling oil are less oil content in compressed air and less temperature rising due to its outstanding heat conduction capability, and thus it improves reliability and efficiency. Furthermore carbon and hydrogen are not contained in this oil so that the inner part of air compressing system can eliminate oxidation and extend operating time longer.
