Airtac GAFR Adjustable Filter Regulator GAFR20008SJNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR20008SJNWK 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 GAFR20008SJNWK
The GAFR20008SJNWK is a genuine AirTAC filter & regulator with both functions sharing one compact body. This 1/4in unit handles 0.15-0.9 MPa (20-130 psi) and uses a 5 um element to trap fine particles for sensitive equipment. The diversion structure spins incoming air to separate liquid water and solid debris into the 25 cc condensate bowl, while the balanced regulator holds the outlet steady as supply pressure varies.
This model ships without a mounting bracket and without a gauge, so plan for panel mounting and read pressure via the 1/8in gauge connection if you add one later. A reverse-flow valve is fitted as an ordering option. The pressed-in self-locking knob resists set-pressure drift from vibration, keeping your regulated output stable in demanding shop-floor environments.

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.

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 GAFR20008SJNWK Is Used
Precision jig clamping
Feed a single pneumatic clamp on a benchtop assembly fixture. The 5 um element protects the clamp's fine seals from abrasive particles, while the regulator holds clamping force steady across shifts.
Portable service cart
Mount this 290 g unit on a mobile maintenance cart to supply clean, regulated air to handheld blow guns or small cleaning nozzles. The compact body and 1/4in port keep the cart light and maneuverable.
Lab air supply point
Provide stable 0.15-0.9 MPa air to a laboratory test rig or prototype station. The 5 um element reduces particle contamination in experimental setups, and the self-locking knob maintains your set pressure during long tests.
Is the Airtac GAFR Adjustable Filter Regulator GAFR20008SJNWK the Right Air-Prep Unit?
Choose the GAFR200 for small jigs, single actuators, or point-of-use stations where a 1/4in port and 290 g mass fit tight spaces. The PC bowl suits general industrial air; the 5 um element catches finer particles than the standard 40 um, though it will need more frequent service. This unit has the semi-auto drain plus manual drain, so you can purge the 25 cc bowl on a schedule or on demand. The J code means no bracket is included, and the N code means no gauge is supplied - the 1/8in connection is ready if you add one. PT threads with an MPa/psi scale match standard regional fittings. The K code adds the reverse-flow valve as a specified option. If your line needs oil downstream, order the matching 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 your inlet pressure near the maximum to reach the full regulated output.
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 GAFR20008SJNWK FAQ
This filter & regulator handles 0.15-0.9 MPa (20-130 psi) working pressure, with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. It operates from -5 to 70 C and must not freeze. The 25 cc drain bowl collects condensate, and the unit weighs 290 g. It uses a 5 um element and has PT threads with an MPa/psi gauge scale.
The J code omits the mounting bracket for installations that use existing panel mounts or custom frames, saving space and weight. The N code means no gauge is fitted; the 1/8in gauge connection is available if you add one later. This configuration suits OEM panels where the operator reads pressure from a central display or where the set point is fixed and verified during maintenance.
