Frequently Asked Questions

Q: What are the differences between the CV-15HS, CV-20HS, and CV-25HS vacuum generator models?

A: The CV-15HS, CV-20HS, and CV-25HS models differ primarily in their port size and flow capacity. Each model is matched to a corresponding thread size (1/8", 1/4", and 3/8" respectively), making them suitable for different pipeline diameters and application scales. All three share the same core specifications for working pressure, materials, and vacuum performance.

Q: What type of air supply does this vacuum generator require?

A: The CV-15/20/25HS vacuum generator operates using standard compressed air as its flow medium. It works within a working pressure range of 1–6 BAR with a rated pressure of 5 BAR. A clean, dry compressed air supply is recommended to maintain optimal performance and longevity.

Q: Is this vacuum generator suitable for robotic and automated pick-and-place applications?

A: Yes, absolutely. This large-flow pneumatic vacuum generator is specifically designed for use with manipulator suction cups in industrial automation. It delivers a suction flow rate of 160 L/min and a vacuum pressure of -92 kPa, making it highly effective for pick-and-place robotics, packaging lines, electronics assembly, and more.

Q: How do I ensure a secure pipeline connection with this vacuum generator?

A: The injector interface features a high-precision internal thread structure machined by CNC equipment, ensuring a tight and firm connection with your pipeline. Simply match the correct thread size to your system (1/8", 1/4", 3/8", 1/2", or 3/4") and thread it securely — no additional adapters are typically needed.
