The Multi-function Vacuum Generator Module VQ (-S3 spec.) is a high-performance vacuum generation unit designed for precise control of large vacuum flows in industrial automation and conveying systems. As a multitasking manifold-type device, it combines two-stage vacuum generation capabilities to deliver efficient suction performance while minimizing energy consumption. Its twin-nozzle design enables staged vacuum control—first generating vacuum from start to a preset reference level using the large-bore nozzle, then maintaining that level with the small-bore nozzle—resulting in significant air savings without compromising operational reliability.
The module is constructed entirely without copper-based metallic materials in its flow paths, ensuring compatibility with environments where copper corrosion or contamination could be problematic. The seal rubber components utilize HNBR or FKM elastomer, both known for their resistance to ozone and high-temperature exposure. This construction supports long-term durability and performance stability under demanding industrial conditions.
The VQ module features a twin-nozzle configuration that connects directly to standard vacuum lines via threaded fittings. It is designed to operate with one control signal—either 24 VDC or 100 VAC—allowing simple integration into existing systems. The module supports both normally closed and normally open valve operation, with double-piloted functionality available for enhanced control flexibility in complex applications.
The vacuum generator operates within a rated pressure range of -100 to +100 kPa and is suitable for air or non-corrosive, incombustible gases as defined by JIS B 8392-1 (Class 1.2.1 to 2.4.3). It functions reliably across an operating temperature range of 5°C to 50°C and humidity levels from 35% to 85% RH, with no dew condensation. The system is tested at a proof pressure of 500 kPa in the vacuum circuit and 1.05 MPa in the air supply circuit for safety assurance.
The VQ (-S3 spec.) model has a fixed width of 31.5 mm, making it suitable for integration into compact or space-constrained systems. It is available with two switch output types: NPN open collector (VUS-33R-N2) and PNP open collector (VUS-33R-P2), each offering two independent output points (SW1, SW2). The maximum load current supported is 125 mA, with a max supply voltage of 30 VDC for NPN and 24 VDC for PNP models.
The module integrates seamlessly into control systems via its switch outputs, which provide reliable signal feedback to PLCs or other automation devices. It operates using indirect pilot valve control, where the vacuum generation is triggered by a control signal—either 24 VDC or 100 VAC—with response times as low as 10 msec (at 24 VDC) and up to 35 msec under specific conditions. The current consumption remains at a maximum of 40 mA when idle, ensuring minimal power draw during standby.
