Airtac GAFR Adjustable Filter Regulator GAFR400C10ASJNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C10ASJNWK 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 5 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 GAFR400C10ASJNWK
The GAFR400C10ASJNWK is a filter and regulator combined into a single body, eliminating the need for separate GAF and GAR units. This 3/8in model handles 0.15-0.9 MPa (20-130 psi) and uses a 5 um element to trap fine particles.
A metal bowl with automatic drain handles condensate, while the 880 g weight signals a unit that needs proper mounting. The balanced regulator holds outlet pressure steady as supply varies, and the pressed-in knob resists vibration drift. No lubricator is included-this unit only filters and regulates.

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 GAFR400C10ASJNWK Is Used
Precision machining
Feed a CNC tool changer or precision vise with 5 um filtered air to protect sensitive valves and cylinders from fine abrasive particles.
Assembly line automation
Supply a multi-station assembly fixture with stable 0.15-0.9 MPa pressure, while the automatic drain removes condensate without manual attention.
Instrument air
Protect laboratory pneumatic instruments or gauges with 5 um filtration and consistent regulated pressure, reducing the risk of particle-induced drift.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C10ASJNWK the Right Air-Prep Unit?
Choose the GAFR400 body for medium-flow lines; its 7000 L/min flow envelope at 0.7 MPa inlet inlet outpaces the GAFR300's 3500 L/min. The metal bowl suits demanding environments, and the automatic drain handles unattended operation. The 5 um element filters finer than the standard 40 um, while the missing gauge means you'll need to add one via the 1/4in connection. The J code omits the bracket, and the K code adds a reverse-flow valve. For lubrication downstream, order the 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.
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 GAFR400C10ASJNWK FAQ
Working pressure range is 0.15-0.9 MPa (20-130 psi), with 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 100 cc and the unit weighs 880 g.
The N code means no gauge is supplied, so you'll need to add one via the 1/4in gauge connection to read outlet pressure. The J code omits the mounting bracket, making this suitable for panel-mount installations or when using an existing bracket.
