Airtac GAFR Adjustable Filter Regulator GAFR500N20SW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR500N20SW is a genuine two-in-one filter & regulator — a diversion-type water/particulate filter and a balanced pressure regulator built into ONE body. It has 3/4" ports, a 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR500N20SW
The GAFR500N20SW is a filter and regulator combined into a single body, eliminating the need for separate GAF and GAR units. This 3/4in model handles 0.15-0.9 MPa (20-130 psi) and uses a 5 um element to trap fine particles for downstream precision equipment.
Its nylon bowl holds 108 cc of condensate, and the unit weighs 950 g, placing it in the mid-large size class. The pressed-in self-locking knob resists set-pressure drift from vibration, keeping your outlet stable.

Figures are the end of the flow curve plotted in the AirTAC catalogue at 0.7 MPa inlet pressure — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. Outlet pressure falls as flow rises, so size a body with headroom above your peak demand.

Where the Airtac GAFR Adjustable Filter Regulator GAFR500N20SW Is Used
Machine headers
Feed a multi-station assembly machine header with clean, regulated air at 3/4in port size, supporting up to 8000 L/min envelope.
Precision valve control
The 5 um element protects sensitive pneumatic valves and positioners from fine particulate, extending their service life.
Paint spray booths
Provide steady 0.15-0.9 MPa pressure to spray guns while the diversion filter spins out water droplets that could ruin finishes.
Is the Airtac GAFR Adjustable Filter Regulator GAFR500N20SW the Right Air-Prep Unit?
Choose the GAFR500 for 3/4in lines needing up to 8000 L/min flow, plotted at 0.7 MPa inlet. The nylon bowl is a build choice, not a performance upgrade - all materials share the same 1.0 MPa max and -5 to 70 C range. This model includes the mounting bracket and a circular gauge with MPa/psi scale, plus both semi-auto and manual drains for flexible service. The 5 um element suits instrument air but needs more frequent changes than the 40 um standard. If you need oil downstream, order the GAFC500-20 combination instead. 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range.
Quick checklist
- ✓ Body size for your peak flow (3/4" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Bracket kept or removed (J); add a lubricator = GAFC
Installation & Maintenance Notes
- check Install with the airflow arrow: IN to OUT, gauge/knob accessible.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Set pressure with the pressed-in self-locking knob; pull to adjust, press to lock.
- check Drain condensate before the 108 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 950 g unit on its bracket, not on the tubing.
This is a filter and regulator only — it delivers filtered, pressure-set air with no added oil. If a downstream tool needs lubrication, add a separate lubricator or order the GAFC500-20 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR500N20SW FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), max pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -5 to 70 C. The drain bowl holds 108 cc and the unit weighs 950 g.
The 5 um element traps much finer particles than the standard 40 um grade, making it suitable for precision valves or instrument air. The trade-off is that the element will need more frequent service or replacement in dirty environments.
