A Cosmic Airmatics FRL unit integrates three critical modules into a single, compact assembly: Filter (F): Removes dust, rust, moisture, and liquid water droplets from the incoming air stream to prevent equipment corrosion and clogging. Regulator (R): Stabilises and controls the downstream air pressure via an integrated pressure gauge, ensuring components operate within safe thresholds. Lubricator (L): Injects a fine, controlled mist of oil into the clean air line to reduce friction and wear on moving components like cylinders and valves.
