Airtac GAFR Adjustable Filter Regulator GAFR600C25SNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C25SNK 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" ports, a 40 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 GAFR600C25SNK
The GAFR600C25SNK is a filter and regulator combined into a single body, handling both air cleaning and pressure stabilization without needing separate units. It uses a 1 inch port, operates from 0.15 to 0.9 MPa (20-130 psi), and comes with a 40 um filter element.
This model features a metal bowl and includes both semi-auto and manual drains, with a 205 cc condensate capacity. The 1880 g weight indicates a substantial unit designed for permanent mounting, not for support from tubing alone.

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 GAFC600-25 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 GAFR600C25SNK Is Used
Machine header supply
Feed a multi-station assembly machine header with clean, regulated air at a steady 0.15-0.9 MPa, using the 1 inch port to handle high demand.
Main line for conveyor system
Protect a long conveyor line's pneumatic controls from water and particles, with the 205 cc bowl reducing how often maintenance needs to intervene.
Central prep for precision tools
Supply a bank of precision pneumatic tools with filtered air, relying on the balanced regulator to keep outlet pressure stable as line pressure fluctuates.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C25SNK the Right Air-Prep Unit?
Choose the GAFR600 for high-flow applications where a 1 inch port and 12000 L/min flow envelope at 0.7 MPa inlet are needed. The metal bowl is the only option for this size, and the standard pressure type covers most industrial needs. This unit includes the mounting bracket and has no gauge, but the 1/4 inch gauge connection is ready for one. The 40 um element handles general workshop air, and the reverse-flow (reflux) valve is fitted as an ordering difference. If oil is needed downstream, order the matching GAFC600-25 combination instead. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the range.
Quick checklist
- ✓ Body size for your peak flow (1" 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 GAFC600-25 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR600C25SNK FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi). Maximum 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 205 cc and the unit weighs 1880 g.
The K code indicates the reverse-flow (reflux) valve is fitted. This is an ordering difference; the catalogue does not detail its function. The unit still filters and regulates air in one body.
