Airtac GAFR Adjustable Filter Regulator GAFR600C25SJN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C25SJN 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 GAFR600C25SJN
The GAFR600C25SJN is a filter and regulator combined into a single body, handling both air cleaning and pressure stabilization without a separate filter-regulator train. This 1-inch port unit weighs 1880 g, placing it in the largest size class where a rigid frame or panel mount is essential rather than relying on tubing support. Its metal bowl holds 205 cc of condensate, reducing the frequency of drain checks compared to smaller bodies.
This model operates in the standard pressure band of 0.15-0.9 MPa (20-130 psi) and comes with a 40 um filter element. The semi-auto drain plus manual drain are both fitted, allowing either automatic purge during operation or manual release when needed. With no gauge supplied, the 1/4-inch gauge connection is available if you add one later to monitor outlet pressure.

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 GAFR600C25SJN Is Used
Machine Header Supply
Feed a multi-station assembly machine header where several actuators and valves draw air simultaneously. The 1-inch port and 12000 L/min plotted envelope at 0.7 MPa inlet support high simultaneous demand without starving downstream devices.
Central Filtration Point
Install at the central point feeding precision pneumatic controls that need clean, regulated air. The 40 um element traps solid particles while the regulator holds a steady outlet pressure, protecting sensitive valves from supply fluctuations.
Heavy Automation Line
Use on a heavy automation line with long distribution runs where pressure drop is a concern. The large 205 cc metal bowl handles condensate from wet supply air, and the semi-auto drain purges automatically during operation.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C25SJN the Right Air-Prep Unit?
Choose the GAFR600 when your line demands high flow capacity; its flow curve is plotted to 12000 L/min at 0.7 MPa inlet, far exceeding the GAFR500's 8000 L/min envelope. The metal bowl is the only option for this body, and the standard pressure type is fixed, so the key choices are the drain style and accessories. This unit ships without the mounting bracket (J code), so plan for a panel cutout or existing bracket, and the absence of a gauge (N code) means you must add one through the 1/4-inch connection to read set pressure. For lines needing oil downstream, the matching GAFC600-25 combination adds a lubricator while keeping the same body and port. The 40 um element suits general shop air; switch to the 5 um element if you need finer filtration for sensitive equipment. The PT thread with MPa/psi gauge scale is standard for most installations. A 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 achieve the highest setpoint.
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 GAFR600C25SJN FAQ
Pressure range is 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). Operating temperature is -5 to 70 C and must not freeze. The drain bowl holds 205 cc and the unit weighs 1880 g. It uses a 40 um element and has a 1-inch port.
The J code means the mounting bracket is omitted, so you must use a panel mount or an existing bracket. The N code means no gauge is fitted; the 1/4-inch gauge connection is available if you add one later. Both options reduce the initial cost when you already have these accessories.
