Airtac GAFR Adjustable Filter Regulator GAFR200C08SJWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200C08SJWK 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 1/4" 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 GAFR200C08SJWK
The GAFR200C08SJWK is a filter and pressure regulator combined into a single body, eliminating the need for separate GAF and GAR units. It spins incoming air to separate liquid water and trap solid particles, then delivers a steady outlet pressure via a balanced, self-locking mechanism that resists vibration drift.
This model has a 1/4in port, a 0.15-0.9 MPa (20-130 psi) working range, and a 5 um element for finer filtration. The metal bowl (25 cc) and semi-auto+manual drain suit applications where condensate is checked regularly. It weighs 290 g, making it a compact choice for small jigs or single actuators.

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 GAFR200C08SJWK Is Used
Single Jig Actuation
Feed a single pneumatic jig or fixture that needs clean, regulated air at a consistent pressure. The 1/4in port and compact 290 g body mount directly on the machine frame.
Bench Top Assembly
Use on a bench-top assembly station where a small air cylinder or vacuum generator requires filtered air and a stable pressure setting without taking up much rail space.
Instrument Air Pre-Filter
The 5 um element makes this suitable for protecting sensitive instruments or precision valves from fine particles, provided the downstream air does not need oil removal.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200C08SJWK the Right Air-Prep Unit?
Choose the GAFR200 body for 1/8in or 1/4in ports where space is tight; step up to a GAFR300 (60 cc bowl, 3500 L/min plotted at 0.7 MPa inlet) if you need more condensate capacity. The metal bowl (C) is a build choice, not a performance upgrade - all bowls share the same 1.0 MPa max and -5 to 70 C rating. This unit ships without a bracket (J), so plan for panel mounting or an existing support. The 5 um element (W) traps finer particles than the standard 40 um, but will need more frequent service. The semi-auto+manual drain requires periodic attention; switch to an A code for automatic draining. The fitted gauge reads MPa/psi (PT thread). The reverse-flow valve (K) is present as an ordering difference. If you need lubrication downstream, order the GAFC200-08 combination instead. 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan for a supply near 1.0 MPa if you need 0.9 MPa out.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 25 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 290 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 GAFC200-08 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR200C08SJWK 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), and temperature range is -5 to 70 C. The drain bowl holds 25 cc, the unit weighs 290 g, and the port is 1/4in. It has a 5 um element and a semi-auto plus manual drain.
The K code indicates a reverse-flow (reflux) valve is fitted. It is an ordering difference from models without K. The catalogue does not detail its function in our data, so confirm the application requirement with the datasheet if you need to know its exact behavior.
