FAQ

Question?
The included pressure gauge shows a range up to 16 bar, but the specifications state a regulation range of 0.5-10 bar. Why is there a difference?

This is common practice. The regulator’s internal mechanism is designed and calibrated for optimal performance and longevity within the 0.5-10 bar range. A standard, more widely available pressure gauge with a higher range (0-16 bar) is used for cost-efficiency and to provide a safety margin for monitoring system pressure, even if it exceeds the intended regulation range. Always operate the regulator within its specified 10 bar limit.

Question?
Can this NL1 series regulator be connected to other Aventics air preparation units?

Yes, the NL1 series is modular. This pressure regulator can be easily assembled into blocks with other NL1 series components, such as filters (F) and lubricators (L), to create a complete FRL (Filter-Regulator-Lubricator) unit. This requires the appropriate connection plates and assembly kits from the NL1 series.

Question?
What is the function of the lockable knob on this regulator?

The lockable knob is a safety and process control feature. Once you have set the desired output pressure, you can push the knob down to lock it in place. This prevents accidental or unauthorized changes to the pressure setting, which is crucial for maintaining consistent performance and safety in automated processes.
