ARO P39124-124 Filter Regulator | ARO-Flo 1000 Series Air Prep

ARO P39124-124 ARO-Flo 1000 Series Filter Regulator

The ARO P39124-124 is a compact piggyback filter/regulator from the ARO-Flo 1000 Series. It combines particulate filtration and adjustable compressed-air pressure regulation in one assembly.

This configuration features 1/4-inch NPT ports, a rated airflow of 47 SCFM, a 5-micron filter element, metal bowl, automatic drain and a 0-140 psi pressure-control range. The unit is supplied without a pressure gauge.

Combined Compressed-Air Preparation

The piggyback design combines two common compressed-air preparation functions into one unit: particulate filtration and downstream pressure regulation.

This arrangement can reduce piping complexity and installation space compared with mounting separate filter and regulator components.

1/4 Inch NPT Port Size

The P39124-124 uses 1/4-inch NPT connections. Confirm that the air-line size and thread standard match the existing pneumatic system before installation.

47 SCFM Airflow

ARO rates this model at 47 SCFM. This airflow rating should be compared with the consumption requirements of the connected pneumatic equipment.

For high-demand applications, make sure the complete air supply system, including tubing, fittings and upstream components, can deliver the required flow without excessive pressure loss.

5-Micron Filtration

The integrated particulate filter provides 5-micron filtration. Removing particulate contamination before the air reaches downstream components can help support reliable operation and reduce contamination-related wear.

Adjustable 0-140 PSI Regulation

The regulator provides an adjustable 0-140 psi control range. Set the downstream pressure according to the operating requirements and pressure limits of the connected equipment.

Metal Filter Bowl

The P39124-124 specifically uses a metal bowl. This distinguishes it from closely related P39124 configurations that use a poly bowl with guard.

Automatic Condensate Drain

An automatic drain is included with this model. The drain helps remove accumulated condensate from the filter bowl and can reduce the need for routine manual draining.

No Pressure Gauge Included

The P39124-124 is a no-gauge configuration. If the installation requires local pressure indication, a compatible gauge or gauge-equipped ARO configuration should be considered.

Compare Similar P39124 Models

• P39124-100: Poly bowl, manual drain, no gauge
• P39124-104: Poly bowl, automatic drain, no gauge
• P39124-120: Metal bowl, manual drain, no gauge
• P39124-124: Metal bowl, automatic drain, no gauge
• P39124-620: Metal bowl, manual drain, gauge
• P39124-624: Metal bowl, automatic drain, gauge

The complete suffix is important because these models can share the same basic size while differing in drain, bowl and gauge configuration.

Application Considerations

The P39124-124 can be used in compatible compressed-air systems supplying pneumatic valves, actuators, industrial equipment, air tools and air-operated pumps.

Before selection, verify:

• 1/4-inch NPT connection requirement
• 47 SCFM flow capacity
• 5-micron filtration requirement
• 0-140 psi pressure range
• Metal bowl requirement
• Automatic drain requirement
• Whether a pressure gauge is required

Ordering Guidance

Specify the complete manufacturer model ARO P39124-124 when ordering. Using the full model number helps prevent substitution with another ARO-Flo 1000 Series version that has a different bowl, drain or gauge configuration.
