Full range

Thanks to our 2-stage claw rotor and supplementary exhaust mechanism*, the ORION Oil-Free Vacuum Pump can achieve all-time high operating efficiency as well as full-range operation from 0 to 100 kPa. ※paten

Continuous operation

Thanks to the 2-stages (2-stage compression), we can achieve continuous operation at the attainable pressure of 100 kPa, despite being oil-free.

Compact, space saving design

The compact modular design that doesn't require side maintenance space, making installation easy, anywhere.

▲ Setup possible with walls on both sides of the product.

Energy saving pump construction that covers the range from low to high degrees of vacuum.

Electrical power consumption optimized over the full range of degree of vacuum (from open-atmosphere to attainable vacuum).

Constructed to prevent over-compression of exhaust air.

At high degrees of vacuum, a back-flow of air is formed in the exhaust process, and this returning air results in a loss of energy.

The KCM series sports a new design that reduces energy losses by reducing the volume just befor opening the exhaust port.

On the other hand, when open, the volume of air increases, there is an over-increase in pressure, and power consumption will rise."Supplementary Exhaust Ports" are established and the power consumption drops.

Expansion Possible to Multi-Unit Control System

Expansion to a multi-unit control system is possible by using our Group Controller.

Intelligent Touch Panel for Easy Operation

Various operating conditions and settings can be confirmed and operated, and operating conditions can be confirmed via the visual and intuitive touch panel.

This is the designed flow rate based on the cylinder volume of the pump. Confirm the actual flow rate based on the pressure-flow diagram.
Under ambient pressure of 1 atm. When operating at high elevations, there will be a difference in operating pressure from operation at a location under 1 atm of pressure. The calculation to measure the ultimate vacuum while operating at other elevations is as follows: Ultimate Vacuum Under Pressure (simplified) [kPa] - Specified Ultimate Degree of Vacuum [kPa] - Altitude [m] 0.0115 [kPa/m]
Operating noise measured at an operating vacuum of 80kPa with 200V / 60Hz power supply, and is not a guaranteed value.
The power supply voltage must not have intermittent fluctuations greater than 10%, or 5% if fluctuations are continued.
If the pump is started where the ambient temperature is around 5℃, a high frequency noise may be heard. The noise will naturally go away in a short time and does not indicate abnormal operation. If a high pitch noise continues for more than 30 minutes, consult with your dealer or a qualified repair person.
Please consult with ORION if the product is to be operated at an elevation above 1,000 m.
