Airtac GAFR Adjustable Filter Regulator GAFR20008ASJNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR20008ASJNWK 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 GAFR20008ASJNWK
The GAFR20008ASJNWK is a filter and pressure regulator combined into a single body, saving rail space and reducing potential leak points compared to separate units. It handles 1/4in porting, delivers a standard 0.15-0.9 MPa (20-130 psi) range, and uses a 5 um element for finer particle removal.
This compact 290 g unit features an automatic drain and a 25 cc condensate bowl, making it suitable for tight spaces on small machines. The pressed-in, self-locking knob maintains the set pressure even when the machine vibrates, keeping the outlet stable.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFR200 is 1/8" if you add one. This unit filters and regulates only; it does not add lubrication.

The filter and the regulator are ONE body here — there is no separate GAF filter or GAR regulator part to assemble. Need lubrication downstream too? Add a lubricator by ordering the matching GAFC200-08 F.R.L. combination instead.

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 GAFR20008ASJNWK Is Used
Small jig clamping
Feed a single pneumatic clamp on an assembly fixture. The 5 um element protects the tiny valve pilot from fine dust, and the automatic drain keeps the bowl from filling during a shift.
Bench-mounted press
Regulate the force of a small arbor press. The self-locking knob holds the set pressure despite the vibration from each stroke, so parts come out consistent.
Lab air supply
Supply clean, regulated air to a test rig or a single instrument. The 5 um element and the stable regulator output suit sensitive measurement tasks.
Is the Airtac GAFR Adjustable Filter Regulator GAFR20008ASJNWK the Right Air-Prep Unit?
Choose this GAFR200 for small jigs or single actuators where 1/4in ports and a 290 g footprint fit. The PC bowl suits general dry indoor use, while the automatic drain handles wet lines without manual attention. This model omits the bracket (J) for panel mounting, has no gauge (N), and uses a 5 um element for finer filtration. The PT thread and the fitted reverse-flow valve (K) complete the specification. If you need lubrication downstream, order the matching GAFC200-08 combination instead. Remember that the 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 (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 GAFR20008ASJNWK FAQ
It is a filter & regulator with a 1/4in port, a 0.15-0.9 MPa (20-130 psi) working range, a 1.0 MPa (145 psi) maximum, and a 1.5 MPa (215 psi) proof pressure. The temperature range is -5 to 70 C. It has a 25 cc drain bowl and weighs 290 g.
The N code means no gauge is supplied; the 1/8in gauge connection is there if you add one later. The J code omits the mounting bracket for installations that use a panel mount or an existing bracket.
