Lubricators for air preparation units (FRL) are critical components in pneumatic systems, ensuring the delivery of properly lubricated air to pneumatic tools and equipment. By injecting controlled amounts of oil into the compressed air stream, these lubricators reduce friction, wear, and corrosion, extending the lifespan of components and improving performance. Widely used in manufacturing, automotive, and assembly operations, FRL lubricators help maintain optimal functionality and reliability in a variety of industrial applications.
