Airtac GAFR Adjustable Filter Regulator GAFR500C20SJWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR500C20SJWK 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 GAFR500C20SJWK
The GAFR500C20SJWK is a filter & regulator with both functions sharing one body, so a separate GAF filter and GAR regulator are not needed. This 3/4in unit works in the 0.15-0.9 MPa (20-130 psi) band and uses a 5 um element to trap fine particles.
Its metal bowl collects condensate from the diversion structure that spins air to separate liquid water and solids. The pressed-in self-locking knob resists set-pressure drift from vibration, keeping the outlet steady as supply pressure varies.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. The fitted circular gauge reads in MPa / psi, set by the PT thread code. This unit filters and regulates only; it does not add lubrication.

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 GAFR500C20SJWK Is Used
Machine header supply
Feed a 3/4in machine header that runs several pneumatic actuators, where the 950 g body mounts on a frame and the 5 um element protects precision valves.
Instrument air line
Use the 5 um element ahead of sensitive instruments or flow controls that need finer particle removal than the standard 40 um grade provides.
Multi-station assembly
Supply a multi-station assembly line where the 108 cc metal bowl holds condensate between scheduled drains and the self-locking knob holds pressure despite machine vibration.
Is the Airtac GAFR Adjustable Filter Regulator GAFR500C20SJWK the Right Air-Prep Unit?
Choose this GAFR500 when a 3/4in port and the 950 g mass fit your header or multi-station line; it is the step up from the GAFR400's 100 cc bowl. The metal bowl suits demanding environments, while the 5 um element filters finer than the standard 40 um grade. This model ships with both semi-auto and manual drains, has no mounting bracket (J), and includes a circular gauge with MPa/psi scale. The fitted reverse-flow (reflux) valve is an ordering difference only. If oil is needed downstream, order the matching 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 GAFR500C20SJWK FAQ
It is a filter & regulator with a 3/4in port, working range 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 108 cc drain bowl, and 950 g weight. The 5 um element and metal bowl are fitted.
The K code indicates the reverse-flow valve is fitted as an ordering difference. The catalogue does not explain its function in our data, so treat it as a specified option for this unit.
