Airtac GAFR Adjustable Filter Regulator GAFR400C10LNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C10LNK 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 3/8" ports, a 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR400C10LNK
The GAFR400C10LNK is a filter and pressure regulator combined into a single body, eliminating the need for separate units. It handles a 3/8in port and delivers a lower pressure range of 0.15-0.4 MPa (20-58 psi) with a 40 um filtering element.
This model features a metal condensate bowl with a 100 cc capacity, weighing 880 g. It includes both semi-auto and manual drains, and is fitted with a reverse-flow (reflux) valve. The unit has no gauge, but its 1/4in gauge connection allows for easy addition.

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 GAFR400 is 1/4" if you add one. This unit filters and regulates only; it does not add lubrication.

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 GAFR400C10LNK Is Used
Precision Fixturing
Power pneumatic clamps on a machining fixture with regulated low pressure, protecting delicate workpieces from excessive force.
Lab Air Supply
Provide a stable, low-pressure air source for sensitive laboratory instruments that require a gentle and consistent flow.
Packaging Line
Control low-pressure actuators in a packaging machine, ensuring gentle handling of products without risk of damage.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C10LNK the Right Air-Prep Unit?
Choose the GAFR400 body for a balance of flow and footprint, with a 3/8in port and a 100 cc drain bowl. The metal bowl suits demanding environments, while the lower pressure type (L) is ideal for applications needing only up to 0.4 MPa. This unit includes the mounting bracket and a 40 um element, with a PT thread. If you need to add lubrication downstream, order the matching GAFC400-10 combination. With a max supply of 1.0 MPa, you have about 0.6 MPa of headroom above the 0.4 MPa regulated top.
Quick checklist
- ✓ Body size for your peak flow (3/8" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ 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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 880 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 GAFC400-10 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR400C10LNK FAQ
This filter & regulator has a 3/8in port, a lower pressure range of 0.15-0.4 MPa (20-58 psi), and a maximum pressure of 1.0 MPa (145 psi). Its proof pressure is 1.5 MPa (215 psi), and it operates in temperatures from -5 to 70 C. The metal drain bowl holds 100 cc, and the unit weighs 880 g.
The 'K' indicates that a reverse-flow (reflux) valve is fitted to this unit. It is an ordering difference from models without this valve. The specific function of the valve is detailed in the full catalogue, which is not included in our data.
