Railway FRL

Filter, regulator and lubricator systems for reliable railway pneumatic performance

Total Pneumatic Solutions supplies Emerson AVENTICS railway FRL systems across New Zealand, designed to deliver clean, dry, and regulated compressed air for rail applications. These air preparation units are critical for ensuring reliable operation of braking systems, suspension, door controls, and other pneumatic functions across rolling stock and rail infrastructure.


What Are Railway FRL Systems?

Railway FRL systems are air preparation units made up of filters, regulators, and lubricators that condition compressed air before it is used within pneumatic systems. In rail environments, maintaining high air quality is essential to prevent failures caused by moisture, contamination, or pressure fluctuations.

These systems are specifically designed to meet the demands of railway applications, where reliability, safety, and compliance with industry standards are critical.

Built for Railway Performance and Compliance

Emerson AVENTICS railway FRL systems are engineered to meet strict rail industry standards, delivering reliable performance in demanding environments. Advanced filtration and air drying capabilities help prevent issues such as freezing, corrosion, and component wear.

These systems are designed for easy integration into both new rail projects and retrofit applications, helping operators maintain performance while reducing lifecycle costs.

  • Removes moisture, dirt, and contaminants from compressed air
  • Provides consistent and regulated air pressure
  • Protects critical railway pneumatic components
  • Reduces system wear and maintenance requirements
  • Improves reliability of braking and control systems
  • Designed for harsh rail environments (vibration, temperature variation)
  • Long service life with minimal downtime

Railway FRL systems are used across a wide range of rail applications in New Zealand, including:

  • Train braking systems
  • Air suspension and leveling systems
  • Door control systems
  • Pantograph control systems
  • HVAC and onboard air systems
  • Rail infrastructure and signalling equipment

Clean and properly regulated air is essential in these systems to ensure safe and consistent operation.
