Q1: What is the CVZ Series?
A: The CVZ Series is a big vacuum flow ejector with a 3-stage multistage nozzle structure for applications that require large suction flow.
Q2: Why is CVZ suitable for porous and heavy workpieces?
A: Because the series combines high suction flow with high vacuum performance, it is suitable for porous workpieces, heavy workpiece suction, and large-capacity degassing.
Q3: What is the maximum suction flow of CVZ?
A: The CVZ-4 model reaches a maximum suction flow of 877 L/min (ANR) at a supply pressure of 0.55 MPa.
Q4: What is special about the 3-stage nozzle design?
A: The 3-stage nozzle design achieves both large suction flow and high vacuum, and the exhaust from one nozzle is used as the supply pressure for the next nozzle for high efficiency.
Q5: Why can CVZ reduce the number of ejectors used?
A: A single CVZ unit can replace multiple ejectors, which helps simplify maintenance by reducing the total number of units.
Q6: Can the nozzle quantity be selected?
A: Yes. The series can be selected with 1 to 4 nozzles according to the required suction flow and air consumption.
Q7: What does the large filter do?
A: The large filter helps separate dust and foreign matter, allows visual clogging checks through the clear case, and supports disassembly cleaning and element replacement.
Q8: Can a pressure sensor be mounted on CVZ?
A: Yes. The body includes a vacuum pressure confirmation port, and a pressure sensor can be mounted directly on the unit.
