The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C25SJNK 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.
The GAFR600C25SJNK is a filter and regulator combined into a single body, handling both air purification and pressure stabilization in one compact unit. This 1-inch port model operates across 0.15-0.9 MPa (20-130 psi) with a 40 um element, and its metal bowl holds 205 cc of condensate.
Its diversion structure spins incoming air to separate liquid water and solid particles before regulation. The balanced, self-locking regulator mechanism maintains the set outlet pressure even as supply pressure fluctuates, resisting drift from vibration. This unit weighs 1880 g and requires proper panel or frame mounting rather than 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.

Feed a multi-station machine header with this 1-inch port unit, providing filtered and regulated air to several actuators or valves from one central point.
Use on a main assembly line manifold where consistent pressure is critical for pneumatic tools and cylinders operating across multiple workstations.
Prepare air for heavy industrial equipment with high flow demands, where the 12000 L/min plotted flow envelope at 0.7 MPa inlet supports large-volume consumption.
This GAFR600 is the largest body in the series, with a 1-inch port and a 205 cc metal bowl. It is the only body offered exclusively with a metal bowl and standard pressure type (0.15-0.9 MPa / 20-130 psi). The J code means no mounting bracket is included, so plan for panel mounting or an existing bracket. The N code indicates no gauge is fitted, but the 1/4-inch gauge connection allows one to be added later. The K code includes a reverse-flow (reflux) valve as an ordering difference. The semi-auto and manual drains are both fitted for flexible condensate removal. If your line needs lubrication downstream, order the matching GAFC600-25 combination instead. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range.
Quick checklist
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.
The GAFR600C25SJNK operates at 0.15-0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. It has a 205 cc drain bowl and weighs 1880 g.
The J code omits the mounting bracket for installations using existing brackets or panel mounts. The N code means no gauge is supplied, though the 1/4-inch gauge connection allows adding one. This configuration suits buyers who have their own mounting and pressure display solutions.
