Airtac GAFR Adjustable Filter Regulator GAFR40010SJK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010SJK 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 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR40010SJK
The GAFR40010SJK is a filter and pressure regulator combined into a single body, saving rail space and reducing potential leak points compared to separate units. It handles 3/8" porting, regulates from 0.15 to 0.9 MPa (20-130 psi), and uses a 40 um element to trap solid particles.
A circular gauge with MPa/psi scale is fitted, and the unit weighs 880 g, indicating a substantial build for machine-level service. The semi-auto and manual drains are both included, giving you immediate control over condensate removal from the 100 cc bowl.

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 GAFC400-10 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 GAFR40010SJK Is Used
Machine tool circuits
Feed a 3/8" line to a machining center's clamping fixtures. The 40 um filter protects precision valves, while the regulator holds a steady 0.4 MPa for consistent clamping force.
Assembly station headers
Mount this unit at a workbench to supply a manifold of pneumatic screwdrivers. The 100 cc bowl handles condensate from a humid plant line, and the manual drain gives operators a simple daily task.
Test bench air supply
Use it on a prototype bench where a clean, regulated 0.6 MPa supply is needed for cylinder actuation tests. The fitted gauge lets you verify set pressure at a glance, and the 880 g weight keeps the unit stable on a plate.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010SJK the Right Air-Prep Unit?
Choose this GAFR400 body when you need 3/8" ports and a 100 cc condensate bowl, stepping up from the GAFR300's 60 cc bowl for longer intervals between draining. The PC bowl suits general-purpose lines, while the included semi-auto and manual drains let you automate purging or handle it manually. This model ships without the mounting bracket (J), so plan for panel mounting or an existing bracket. The standard pressure type (S) covers 0.15-0.9 MPa, and the fitted gauge reads in MPa/psi with PT threads. The 40 um element is the default choice for standard shop air. If your line needs lubrication downstream, order the matching GAFC400-10 combination instead. Note that 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan your inlet pressure accordingly.
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 GAFR40010SJK FAQ
It is a filter & regulator with a 3/8" port, 40 um element, and a 100 cc drain bowl. The pressure range is 0.15-0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Operating temperature is -5 to 70 C. The unit weighs 880 g and has a flow curve plotted to 7000 L/min at 0.7 MPa inlet.
The 'K' code indicates a reverse-flow (reflux) valve is fitted, which is an ordering difference from the standard unit. The 'J' code means the mounting bracket is not included, so you will need to use a panel mount or an existing bracket. The unit still includes the semi-auto and manual drains and a fitted gauge.
