The Multi-function Vacuum Generator Module VX (-S3 spec.) is a specialized vacuum generation unit designed for use in secondary battery manufacturing processes. It serves as a multitasking manifold solution, enabling precise and responsive control of vacuum operations through its high-cycle performance and optimized valve response. This module ensures reliable operation during critical stages of production where rapid on/off switching and consistent vacuum levels are essential.
The unit is constructed without any copper-based metallic materials in its flow paths, ensuring compatibility with non-corrosive and ozone-sensitive environments. Sealing components utilize low-concentration ozone-resistant elastomers such as HNBR or FKM, which are specifically selected for their durability under vacuum conditions. The internal element material is PVFM (polyvinyl formal), providing chemical resistance and long-term stability in demanding industrial settings.
The module features two selectable installation methods, offering flexibility during integration into existing systems. It connects via standard interfaces compatible with solenoid valves and pneumatic circuits. Pressure sensing is supported through a diffused semiconductor pressure switch, which allows for precise monitoring of vacuum levels within the operational range of -99 to 0 kPa.
The module operates within an air medium compliant with JIS B 8392-1 (Class 1.2.1 to 2.4.3). It functions over a pressure range from 0.3 to 0.7 MPa in the supply circuit and delivers vacuum down to -100 kPa, with an operating temperature range of 5 to 50°C and humidity levels between 35% and 85% RH (no dew condensation). Proof pressures are 1.05 MPa for the air supply circuit and 0.2 MPa for the vacuum circuit. The rated voltage is 24 VDC ±10%, or 100 VAC ±10%, with a 12 to 24 VDC ±10% range (ripple P-P: 10% max).
The module offers two pressure setting options—two settings for standard configurations and one setting for simplified setups. It is available in a lightweight, compact design that meets market demands for space-efficient and high-performance vacuum solutions without compromising on operational reliability or cycle speed.
Integration of the VX (-S3 spec.) module supports both indirect operation via pilot valve and direct-operated poppet valve configurations. The valve type is normally closed by default, with a double-piloted option available for specific applications. Response times are optimized: under 24 VDC, ON→OFF response reaches as low as 3 msec (for direct operation), while OFF→ON response is within 8 msec (-S3 spec.). These characteristics ensure fast and repeatable vacuum cycling critical in high-speed manufacturing environments.
