CONVUM NCV2 Wide-Range Vacuum Ejector

• Wide-range nozzle design: The NCV2 Series uses a new wide-range nozzle that supports operation across a broad supply pressure range.
• Maintains required vacuum pressure: It can maintain the vacuum pressure required for suction over a wide supply pressure range, allowing adjustment of suction flow and air consumption.
• Longer filter replacement cycle: The built-in cyclone filter separates foreign matter from the intake air, reduces element clogging, and extends the replacement cycle.
• Standard energy-saving pressure sensor: The series includes a pressure sensor with solenoid valve control, allowing efficient control using only suction and blow-off command signals.
• Smart body design: The pressure sensor and solenoid valves are stored inside the body, and the wiring is gathered on one side to reduce contact and wire interference.

Q1: What is the NCV2 Series?
A: The NCV2 Series is a wide-range vacuum ejector with a new wide-range nozzle that can maintain the vacuum pressure required for suction across a broad supply pressure range.

Q2: What is the key feature of the wide-range nozzle?
A: It can maintain vacuum pressure of -80 kPa or higher over a broad supply pressure range, allowing adjustment of suction flow and air consumption.

Q3: Why can NCV2 reduce the need for model changes after selection?
A: Because it can maintain the required vacuum pressure across a wide supply pressure range, it reduces the need to reselect the nozzle or replace the ejector after installation conditions change.

Q4: What does the cyclone filter do?
A: The cyclone filter creates a swirling flow in the filter case and uses centrifugal force to separate foreign matter from air, reducing element clogging and extending the replacement cycle.

Q5: What does the energy-saving pressure sensor do?
A: It includes solenoid valve control and allows efficient operation using only suction and blow-off command signals.

Q6: What is special about the NCV2 wiring design?
A: The pressure sensor and solenoid valves are stored inside the body, and the wiring is concentrated on one side to reduce wire break risk and interference with nearby equipment or tubing.

Q7: How should the rated pressure range be understood?
A: The rated pressure range of NCV2 is 0.3 to 0.6 MPa, which is the stable operating range for maximum vacuum pressure.

Q8: What should be noted near a supply pressure of 0.25 MPa?
A: Around 0.25 MPa, pulsation may occur in the maximum vacuum pressure, so the stable rated pressure range is specified as 0.3 to 0.6 MPa.
