Airtac GAFR Adjustable Filter Regulator GAFR600C25ASJK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C25ASJK 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 GAFR600C25ASJK
The GAFR600C25ASJK is a filter and pressure regulator combined into a single body, handling both filtration and pressure control for large industrial air systems. It features a 1 inch port, a working range of 0.15-0.9 MPa (20-130 psi), and a 40 um element, with a metal bowl and an automatic drain.
This unit's 1880 g mass and 1 inch port place it at the top of the GAFR size range, designed for high-flow machine headers. Its diversion structure spins incoming air to separate liquid water and solid particles into the 205 cc drain bowl, while the balanced, self-locking regulator maintains the set outlet pressure despite supply variations.

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 GAFR600C25ASJK Is Used
Machine Header Supply
Feed a multi-station assembly machine header with a single, clean, regulated air supply. The 1 inch port and 205 cc bowl handle high demand and reduce drain frequency.
High-Flow Pneumatic Line
Supply a bank of large bore cylinders or rotary actuators on a packaging line. The 40 um element protects downstream valves while the regulator stabilizes pressure.
Central Plant Air Drop
Install at a central distribution point for a production cell. The automatic drain and metal bowl suit a fixed installation where maintenance access is limited.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C25ASJK the Right Air-Prep Unit?
Choose the GAFR600 body for the largest flow demands, with a 1 inch port and a flow curve plotted to 12000 L/min at 0.7 MPa inlet. The metal bowl is the only option for this size, and the automatic drain handles condensate without manual intervention. This model has no mounting bracket, so plan for a panel or frame mount, and the fitted circular gauge shows pressure on an MPa/psi scale. The 40 um element is standard, and the reverse-flow (reflux) valve is fitted as an ordering difference. For lines needing oil downstream, the matching GAFC600-25 combination adds a lubricator. 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" 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 GAFR600C25ASJK FAQ
The GAFR600C25ASJK is a filter & regulator with a 1 inch port. Its pressure range is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Operating temperature is -5 to 70 C. The drain bowl holds 205 cc and the unit weighs 1880 g.
The K code indicates a reverse-flow (reflux) valve is fitted to the unit. This is an ordering difference from models without the K code. The specific function is detailed in the catalogue page for the valve, which is not included in our data.
