Q1: What is the VFL-M5 vacuum inline filter used for?
A: It filters dust/particles in vacuum lines to help protect vacuum-side components and improve stability.
Q2: When should I add a vacuum line filter?
A: Add one when dust is present, contaminants may enter the line, or when vacuum-side components need protection.
Q3: Why use a clear-body vacuum filter?
A: The clear body enables quick visual inspection, making maintenance timing easier and reducing downtime.
Q4: Can I use the VFL-M5 on positive pressure lines?
A: No. The VFL-M5 is for vacuum lines only and should be used on vacuum circuits.
Q5: What is the filtration rating of the VFL-M5?
A: The filtration rating is 37 µm, suitable for low-flow vacuum piping protection.
Q6: Any installation precautions?
A: Resin body—do not exceed 0.24 N·m tightening torque and avoid excessive lateral load.
Q7: How often should I service the filter?
A: It depends on dust level and cycle rate. Inspect if suction drops or response slows, then clean/replace.
Q8: What applications is the VFL-M5 best for?
A: Tight spaces, small devices, and low-flow vacuum lines where compact inline protection is needed.
