Parker Air Preparation Products | Global FRLs


The Global Air Preparation System is a comprehensive modular system from Parker, available in three body sizes to meet all of your air filtration and regulation needs.

The system's components can be assembled into a variety of combinations using lightweight body connectors. Filters remove moisture, vapors and particulates to produce a clean, dry pneumatic system. Regulators provide accurate pressure regulation, available in relieving and non-relieving types. Lubricators deliver proportional, precise oil drip over a wide range of air flows.

  • NPT, BSPP and BSPT ports
  • Robust, lightweight aluminum construction
  • Positive bayonet latch to ensure safe and correct fitting
