The PAV‑B8 is a powerful, dry (oil-free) vacuum pump developed by Flying Vision, specifically designed for field work and use with vacuum boxes (bubble test) in NDT leak testing. With its dry vane technology, it provides reliable vacuum without the need for lubrication or risk of contamination, and can operate in any position.

Key features and benefits

• High performance – Nominal air flow of 8 m³/h and final vacuum of 150 mbar.

• Oil-free operation – Self-lubricating graphite bushing eliminates the need for oil lubrication and reduces maintenance.

• Robust construction – Stainless steel housing provides long life and high resistance to field conditions.

• Low noise – Only 58 dB at 50 Hz, making it more comfortable to use during inspections.

• Operation in all positions – Because the pump is oil-free, it can be used upside down or in an inclined position without risk of weakening.

• Convenient connections – Fast “Rectus 21” quick connector for easy connection to vacuum box.

• Air and particle filter – Built-in two-stage filter protects the pump from dust and moisture.

• Adjustable vacuum pressure – Adjustable valve for minimum vacuum provides better control during testing.

• Power Options – Available in 110/120V and 220/240V versions, depending on your work location.

• IP protection – IP54 rating protects against dust and splashes, suitable for field use.
