Airtac GAFR Adjustable Filter Regulator GAFR40010ASNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010ASNK 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 GAFR40010ASNK
The GAFR40010ASNK is a filter and regulator combined into a single body, eliminating the need for separate GAF filter and GAR regulator units. This 3/8in port model handles 0.15-0.9 MPa (20-130 psi) with a 40 um element, and its automatic drain clears condensate without manual attention.
The 100 cc drain bowl and 880 g weight place this unit in the mid-size class, suitable for machine headers feeding several actuators. A reverse-flow (reflux) valve is fitted, and the PT thread option with MPa/psi gauge scale matches common regional installations.

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.

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 GAFR40010ASNK Is Used
Machine tool circuits
Feed a 3/8in header on a CNC machine or press, where the 100 cc bowl handles condensate from high-cycling solenoids and the automatic drain prevents downtime.
Assembly line stations
Supply multiple pneumatic cylinders on a conveyor work cell, with the 7000 L/min envelope at 0.7 MPa inlet supporting simultaneous actuation.
Packaging equipment
Regulate air for film sealing and labeling machinery, where stable pressure from the balanced regulator keeps cycle times consistent.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010ASNK the Right Air-Prep Unit?
Choose the GAFR400 body when you need 3/8in or 1/2in ports with a 100 cc drain bowl, stepping up from the GAFR300's 60 cc bowl for longer intervals between drains. The PC bowl suits standard shop air; select the metal or nylon option if your environment demands different material compatibility. This model includes the mounting bracket and an automatic drain, ideal for unattended operation. The standard pressure type covers 0.15-0.9 MPa (20-130 psi), while the 40 um element handles general filtration needs. No gauge is fitted, but the 1/4in gauge connection allows easy addition. The K code indicates the reverse-flow valve is attached. For lines requiring lubrication downstream, order the matching GAFC400-10 combination instead. Max supply 1.0 MPa 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 GAFR40010ASNK FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi) with 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the unit weighs 880 g with a 3/8in port and 40 um element.
The K indicates a reverse-flow (reflux) valve is fitted. This is an ordering difference from the standard version; the valve's detailed function is covered in separate catalogue documentation not included here.
