Airtac GAFR Adjustable Filter Regulator GAFR500N20ASWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR500N20ASWK 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 GAFR500N20ASWK
The GAFR500N20ASWK is a filter & regulator that combines both functions in a single body, eliminating the need for separate filter and regulator units. It handles a 3/4in port and delivers a standard pressure range of 0.15-0.9 MPa (20-130 psi), with a 5 um element for finer filtration.
This unit uses a diversion structure to spin the air, separating liquid water and solid particles into the 108 cc nylon bowl. The pressed-in self-locking knob maintains the set pressure even under vibration, while the balanced mechanism keeps the outlet steady as supply pressure varies.

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 GAFR500N20ASWK Is Used
Machine header supply
Feed a 3/4in machine header serving multiple pneumatic actuators, where the 5 um element protects precision valves from fine particulate contamination.
Multi-station assembly line
Regulate air for a multi-station assembly conveyor, using the automatic drain to handle condensate in a continuously running production environment.
Process equipment skid
Mount on a process equipment skid where the 950 g body with included bracket provides stable support and the 108 cc bowl reduces drain frequency.
Is the Airtac GAFR Adjustable Filter Regulator GAFR500N20ASWK the Right Air-Prep Unit?
Choose the GAFR500 for 3/4in port applications that need a 950 g unit with a flow curve plotted to 8000 L/min at 0.7 MPa inlet. The nylon bowl offers a build alternative to PC or metal, while the automatic drain handles condensate without manual intervention. This model includes the mounting bracket, has a fitted gauge with MPa/psi scale, and uses a 5 um element for finer particle removal. The reverse-flow (reflux) valve is fitted as an ordering difference. If oil is needed downstream, order the matching GAFC500-20 combination instead. Remember that 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 GAFR500N20ASWK FAQ
The GAFR500N20ASWK has a pressure range of 0.15-0.9 MPa (20-130 psi), max pressure of 1.0 MPa (145 psi), proof pressure of 1.5 MPa (215 psi), and temperature range of -5 to 70 C. It has a 108 cc drain bowl and weighs 950 g.
The automatic drain (A code) expels condensate from the 108 cc bowl without manual intervention, making it suitable for unattended operation or wet air lines. This contrasts with the semi-auto+manual drain found on models without the A code.
