Airtac GAFR Adjustable Filter Regulator GAFR600C20SNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C20SNWK 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 GAFR600C20SNWK
The GAFR600C20SNWK combines a 40 um-equivalent diversion filter and a balanced pressure regulator in a single 1880 g metal-bodied unit with a 3/4in port. It spins incoming air to separate liquid water and solid particles into the 205 cc condensate bowl, then delivers a steady 0.15-0.9 MPa (20-130 psi) outlet regardless of supply fluctuations.
This model ships with the 5 um element for finer filtration, a semi-auto plus manual drain, and the reverse-flow valve fitted. The pressed-in self-locking knob resists vibration-induced drift, keeping the set pressure stable in high-shock environments. No lubricator is present; the single bowl is for condensate only.

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 GAFR600 is 1/4" 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 GAFC600-20 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 GAFR600C20SNWK Is Used
Machine tool header
Feed a multi-station machining center with stable 0.15-0.9 MPa air, filtering coolant mist and particulates before they reach precision valves.
Assembly line manifolds
Supply a bank of pneumatic actuators on a conveyor system, with the 205 cc bowl reducing drain frequency during continuous shifts.
Test bench instrumentation
Provide clean, regulated air to calibration fixtures where the 5 um element protects sensitive gauges and flow meters.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C20SNWK the Right Air-Prep Unit?
Choose the GAFR600 body for high-flow lines up to 1in ports; the 3/4in version here handles a plotted flow envelope of 12000 L/min at 0.7 MPa inlet, about 1.5x the GAFR500's 8000 L/min envelope. The metal bowl suits demanding shop-floor conditions, while the standard S type covers 0.15-0.9 MPa (20-130 psi). The included bracket simplifies panel mounting, and the 5 um element traps finer particles for sensitive downstream equipment. The semi-auto drain requires periodic manual checking; the K reflux valve is fitted as an ordering option. For lubrication downstream, order the matching GAFC600-20 combination instead. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range.
Quick checklist
- ✓ Body size for your peak flow (3/4" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: Metal (C) only
- ✓ 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 205 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1880 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 GAFC600-20 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR600C20SNWK FAQ
Working pressure is 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. The drain bowl holds 205 cc, the unit weighs 1880 g, and the port is 3/4in. It uses a 5 um element and has a semi-auto plus manual drain.
The N code after the port means no gauge is supplied. The gauge connection on GAFR600 is 1/4in, so you can add a compatible gauge later. Without one, the set pressure cannot be read directly on the unit.
