A water ejector is an ejector that uses water as a driving source to suction and exhaust gas. It can achieve an inlet pressure equivalent to the vapor pressure of the driving water, making it effective for exhausting gases that contain condensable and corrosive gases, as well as dust. It can also be used as the final stage in a multi-stage steam ejector system.

The ejector has a simple structure without mechanical drive components, so there are almost no occurrences of failure.

A steam ejector is an ejector that uses gas as a driving source to suction and exhaust gas. It is characterized by its simple structure, low failure rate, and ease of handling. Additionally, by arranging multiple ejectors in series, it is possible to reach higher vacuum levels.

The exhaust unit delivered for the leak test of automotive parts this time features the grease-lubricated ball bearing turbo molecular pump "TG350F" as the main pump, with a direct-coupled oil rotary vacuum pump as the auxiliary pump. It connects to the vacuum chamber via a 100mm diameter angle valve installed on the intake port of the turbo molecular pump through a short pipe. Both the turbo molecular pump and the oil rotary vacuum pump are mounted on a cart with wheels. Additionally, since both the main and auxiliary pumps are air-cooled, the exhaust unit can operate solely on AC100V input. With the touch panel controller mounted on the cart, it is possible to perform automatic operation of the entire system, including the operation of the vacuum gauge and slow leak valve, as well as manual operation of various components. The grease-lubricated ball bearing turbo molecular pump TG350F is resistant to external vibrations, allowing it to maintain rated operation while the cart is being moved. This simple yet highly reliable exhaust unit supports the manufacturing of automotive parts. *For more details, please refer to the PDF document or feel free to contact us.*

This time, in conjunction with the establishment of new equipment with increased manufacturing capacity, a larger vacuum exhaust system with a higher exhaust speed was necessary to evacuate the enlarged reaction vessel. Therefore, we manufactured and delivered a vacuum exhaust system. Since it is used in the adhesive manufacturing process, we considered the possibility of adhesive materials sticking and stopping the pump. To ensure that vacuum evacuation can continue even if one system stops due to sticking, it is configured with two parallel exhaust systems. The main exhaust system "PRD25-60" is a combination of a Roots vacuum pump (mechanical booster pump) "RD2500" and a screw-type dry vacuum pump. The gas contact section is oil-free, eliminating the need for frequent oil changes due to oil contamination from the intake gas. The auxiliary exhaust system "PRM25-45" combines a Roots vacuum pump (mechanical booster pump) "RD2500" with an economical oil rotary vacuum pump "P450," which is relatively resistant to adhesive material sticking. Additionally, since the installation site is a hazardous materials manufacturing facility, the motor is designed to be explosion-proof and pressure-resistant. *For more details, please refer to the PDF document or feel free to contact us.
