PneumaticPlus PPP2-N02BG Air Filter Regulator Combo | 1/4" NPT, 47 SCFM, 5 Micron | Poly Bowl, Manual Drain
The PneumaticPlus PPP2-N02BG is a piggyback compressed air filter regulator designed to deliver clean, regulated air at the point of use for pneumatic tools, automation panels, and industrial compressed air systems and circuits.
It combines 5 micron particulate filtration with a 0–140 PSI regulating range and a compact filter regulator unit form factor, helping reduce contamination-related issues and pressure fluctuations in downstream components.
ARO® Cross-Reference: PneumaticPlus PPP2-N02BG replaces ARO® P39124-600-VS and P39124 variations. PPP Series compressed air filter regulator combos are designed to match the corresponding ARO part family.
Common Applications & Use Cases
The PPP2-N02BG is commonly used where compact point-of-use air preparation helps protect downstream pneumatic components.
- Workstations & air drops: Filtration + pressure control at benches and tool stations.
- Machine panels / OEM equipment: Compact piggyback filter regulator assembly reduces fittings and saves space.
- Automation circuits: Helps reduce particulate contamination to valves, cylinders, and actuators.
- Maintenance/retrofit: Simple upgrade for an existing 1/4" NPT compressed air line.

Frequently Asked Questions
Q: What does a piggyback filter regulator do?
A: It combines particulate filtration and pressure regulation to help deliver clean, stable compressed air to downstream tools and components.
Q: Is PPP2-N02BG a replacement for ARO® P39124-600-VS?
A: Yes. PPP2-N02BG is intended as a replacement for ARO® P39124-600-VS (and P39124 variations).
Q: What does 47 SCFM mean?
A: It is the rated airflow capacity used for sizing so the filter regulator does not become a restriction in your circuit.
Q: When should I select PPP3-N02BG instead?
A: Choose PPP3-N02BG when you need higher airflow but must keep 1/4" NPT piping; it uses 1/4" threads on a larger body to reduce restriction.
Q: What types of applications is PPP2-N02BG best suited for?
A: It is best suited for point-of-use compressed air preparation on small tools, automation panels, and general industrial air lines where 1/4" NPT and moderate flow are required.
