Design and Performance Characteristics
The Festo VN-10-H-T3-PQ2-VQ2-RO1-F1A (manufacturer ID 8187684) is a T-shape vacuum generator engineered for high-vacuum ejector duty. Its Laval nozzle has a nominal width of 0.95 mm, and the unit delivers a maximum suction rate of 25 l/min at an operating pressure of 3.1 bar. The generator achieves a maximum vacuum of 89% when supplied at 4.5 bar, with a nominal operating pressure of 6 bar. The open silencer design keeps the noise level at 74 dB(A) under nominal conditions, making it suitable for environments where acoustic comfort is a consideration.
Integration and Mounting Flexibility
This vacuum generator can be mounted in any position, which simplifies installation into existing automation layouts. It offers two mounting options: through-hole mounting or mounting with accessories. The compact width of 14 mm and a product weight of only 24 g allow for space-saving integration into end-of-arm tooling or modular handling systems. Pneumatic connections are QS-6 for both the supply (connection 1) and vacuum (connection 3), while the exhaust port features an integrated open pneumatic muffler.
Material Selection and Environmental Suitability
The housing is made of reinforced POM, with the nozzle and connecting threads also in POM. The jet nozzle is wrought aluminum alloy, and seals are NBR. The muffler is PE. These materials are RoHS-compliant and meet the requirements for Li-ion battery production, with restrictions on copper, zinc, and nickel content (except for specific exceptions). The unit is rated for low corrosion stress (CRC 1) and conforms to VDMA24364-B1/B2-L for LABS (PWIS) compatibility, making it appropriate for paint shops and similar sensitive applications.
Operating Conditions and Media
The VN-10-H-T3-PQ2-VQ2-RO1-F1A operates on compressed air per ISO 8573-1:2010 [7:4:4] and cannot be used with oil-lubricated media. The permissible operating pressure range is 1 to 8 bar, with a nominal operating pressure of 6 bar. The medium and ambient temperature range is 0°C to 60°C. The air supply time at nominal operating pressure is 1.1 seconds, which is a useful parameter for cycle time calculations in pick-and-place applications.
Practical Application Considerations
For engineers and procurement teams, the key selection criteria are the high vacuum level (89%) and the moderate suction rate (25 l/min), which make this generator suitable for handling small to medium-sized workpieces in battery production, electronics assembly, and packaging. The open silencer reduces exhaust noise, but note that the muffler is open to the environment, so ensure that the exhaust air is directed away from sensitive areas. The maximum tightening torque is 0.5 Nm, so care must be taken during installation to avoid damaging the POM threads. The unit's light weight and compact size also facilitate dynamic motion in robotic applications.
