The "T-Station75" is a turbo exhaust unit newly developed by Edwards that allows for the starting and stopping of the system with the push of a single button. It is capable of controlling Edwards' active gauges and vent valves, and when a gauge is attached, it can control the delayed start of the turbo pump based on time or pressure, making it suitable for common needs in the laboratory. 【Features】 ■ System start and stop can be performed with a single button ■ Capable of controlling Edwards' active gauges and vent valves ■ Can control the delayed start of the turbo pump based on time or pressure when a gauge is attached ■ Suitable for common needs in the laboratory *For more details, please refer to the PDF document or feel free to contact us.

• Ventilation and Exhaust

The "Oil-Free Scroll Pump" is a product that achieves a clean vacuum without using lubricating oil in the exhaust mechanism. Its simple structure allows for quick disassembly and assembly, and since it does not use oil, it provides a clean maintenance environment. Additionally, it completely isolates the bearings from the vacuum environment, preventing degradation of the bearing grease due to water vapor, resulting in an even cleaner vacuum. 【Features】 ■ Clean exhaust ■ Quick disassembly and assembly due to simple structure ■ nXDS and XDS pumps utilize patented bearing shields ■ Prevents degradation of bearing grease due to water vapor *For more details, please refer to the PDF document or feel free to contact us.

The "Small Rotary Pump" is a product that operates smoothly from atmospheric pressure to high vacuum using a pressurized oil supply method. In particular, the RV series is designed to achieve smooth continuous operation not only at high vacuum but also at high throughput (high pressure), incorporating an oil flow adjustment valve. It completely prevents oil backflow during sudden stops, such as power outages, keeping the system in a vacuum state. Additionally, due to precision machining and a special oil supply method, it has extremely low vibration and noise, with the RV series operating at around 48 dB(A). 【Features】 ■ Smooth operation from atmospheric pressure to high vacuum using a pressurized oil supply method ■ Oil backflow prevention mechanism ■ Low vibration and low noise ■ Complete prevention of oil backflow during sudden power outages *For more details, please refer to the PDF document or feel free to contact us.

• Vacuum pump

The "Air Open-Close Type BV Series" is a vacuum valve with excellent reliability, driven by a rack and pinion mechanism. There are no restrictions on installation posture or direction, and its conductance performance relative to diameter is the highest among vacuum valves. Additionally, the air cylinder ensures reliable operation by doubling the thrust when open, and it achieves shock mitigation through the air cushion effect at the stroke end. 【Features】 ■ Excellent reliability ■ No restrictions on installation posture or direction ■ Achieves shock mitigation *For more details, please contact us.
