ULVAC to Develop and Launch the LS series of Dry Vacuum Pumps – High pumping speed combined with low power consumption –

April 18, 2018 ULVAC, Inc.

ULVAC, Inc. (Headquarters: Chigasaki, Kanagawa; President and CEO: Setsuo Iwashita; hereafter referred to as ULVAC) is pleased to announce that the company has developed and commercialized a new series of dry vacuum pumps to be called the LS series. The series will be launched on April 18, 2018.


Dry vacuum pumps are used in many production lines, including those for electronic parts and displays. Environmental considerations have led to dry vacuum pumps becoming mainstream thanks to their low power consumption. However, typical dry vacuum pumps with low power consumption tend to have the problem of long pumping down time, as they have a low pumping speed near atmospheric pressure.


To solve this problem, ULVAC has developed a new dry vacuum pump series called LS series that combines high pumping speed with low power consumption. By increasing the pumping speed near atmospheric pressure, ULVAC has realized a dry vacuum pump with high pumping speed (thereby shortening pumping down time) that uses the original technology developed by the company to reduce power consumption.

The LS series lineup will include 4 models of dry vacuum pumps with high pumping speed and low power consumption, providing pumping speed ranging from 120 to 1200 m3/h. Customers can select a pump with an exhaust capacity optimized for the size and usage conditions of their equipment.


■High pumping speed

The LS series has high pumping speed near atmospheric pressure, thereby shortening pumping down time.

This allows for a reduction in pumping down time of approximately 20% compared to typical dry vacuum pumps with low power consumption.

■Low power consumption

While realizing a high pumping speed, the LS series achieves industry top-class power consumption of no more than 0.6 kW upon reaching ultimate pressure.

■Low noise

The specialized built-in silencer reduces the noise level to no more than 61 dB (A).


[Sales price and target]

Sales price: 1.5 million yen and up (excluding sales tax)

Sales target: 1,000 units per year
