Airtac GAFR Adjustable Filter Regulator GAFR400C10ASN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C10ASN 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 GAFR400C10ASN
The GAFR400C10ASN is a filter and regulator combined in one body, saving rail space and reducing potential leak points compared to separate units. It handles 3/8" ports and delivers a regulated 0.15-0.9 MPa (20-130 psi) output while filtering to 40 um.
This metal-bowl version uses an automatic drain to expel condensate without manual attention, and its 100 cc bowl suits continuous operation. The balanced regulator holds the set pressure steady as supply varies, and the pressed-in knob resists drift from vibration.

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 GAFR400C10ASN Is Used
Machine tool circuits
Feed a 3/8" line to a CNC clamping fixture or a small press, where steady pressure and clean air protect precision valves.
Assembly station headers
Supply a multi-operator workbench with filtered, regulated air for screwdrivers and vacuum pickups, with the auto drain reducing downtime.
Test rigs and benches
Use in a lab or QA station where a stable 0.15-0.9 MPa supply is needed for gauges or leak testers, with the metal bowl resisting knocks.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C10ASN the Right Air-Prep Unit?
Choose the GAFR400 body for medium-flow lines; its 7000 L/min plotted envelope at 0.7 MPa inlet sits between the GAFR300 (3500 L/min) and GAFR500 (8000 L/min). The metal bowl (C) suits demanding environments, while the automatic drain (A) handles wet or unattended lines without manual checks. This model omits the gauge (N), so the 1/4" gauge connection is available if you add one later; the included bracket simplifies panel mounting. The standard S type covers 0.15-0.9 MPa, and the 40 um element balances filtration with service life. If your line needs lubrication downstream, order the matching GAFC400-10 combination instead. 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 GAFR400C10ASN FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C. The drain bowl holds 100 cc, the unit weighs 880 g, and the port is 3/8".
The N code means no gauge is supplied, saving cost when you use a panel-mounted gauge. If you add one later, the GAFR400 body has a 1/4" gauge connection.
