EBARA Dry Pump (EV-A Model)

Hello, this is VALVEPARK.

Today we introduce the EBARA Dry Pump (EV-A Model) - a vacuum pump that is seeing growing adoption across industrial sites. With its air-cooled design, easy installation, and low maintenance requirements, it is a versatile vacuum pump used across general industry and precision analytical equipment alike.

What Is a Dry Pump?

In simple terms, it is a machine that continuously draws in air - just like deflating a balloon, it removes the air inside the equipment to create a completely empty state (vacuum).

What Makes the EV-A Model Special?

The EBARA EV-A Model is an Air-Cooled Dry Vacuum Pump based on a non-contact Roots-type mechanism, designed for high efficiency. Its standout feature is that it requires neither oil nor cooling water, simultaneously achieving a clean process environment and minimized maintenance. It delivers stable vacuum performance for Load Lock chambers, analytical instruments, and a wide range of general industrial processes.

In plain language: no water and no oil needed! Typical machines require oil or water to operate, but the EV-A Model needs neither - making it cleaner and more convenient.
