Airtac GAFR Adjustable Filter Regulator GAFR40015S
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015S 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 1/2" 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 GAFR40015S
The GAFR40015S is a filter and regulator combined into a single body, handling both air preparation steps without a separate filter unit upstream. It uses a diversion structure to spin the incoming air, dropping liquid water and solid particles into the 100 cc condensate bowl while the balanced regulator holds a steady outlet pressure.
This model has a 1/2in port and a standard pressure range of 0.15-0.9 MPa (20-130 psi). It comes with a 40 um element, a circular gauge with MPa/psi scale, and both semi-auto and manual drains fitted. The 880 g body with its 100 cc bowl places it in the mid-size class, suited for machine headers or multi-station lines.

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 GAFC400-15 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 GAFR40015S Is Used
Machine header supply
Feed a 1/2in header on a stamping press or assembly machine, providing filtered and regulated air to multiple actuators from one central point.
CNC coolant and clamp circuits
Protect precision valves and cylinders on a CNC lathe or mill, where stable 0.15-0.9 MPa pressure keeps clamping forces consistent.
Packaging line air prep
Condition air for a carton erector or strapping machine, using the 100 cc bowl to handle condensate from a busy production line.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015S the Right Air-Prep Unit?
Choose the GAFR400 for applications needing a 1/2in port and a 100 cc condensate bowl, stepping up from the GAFR300's 60 cc bowl when you want fewer drain interventions. The PC bowl suits general industrial use, while the included mounting bracket supports the 880 g unit properly on a panel or frame. This standard type covers 0.15-0.9 MPa (20-130 psi), and the 40 um element handles typical workshop air; select the W option for 5 um filtration if you feed precision valves. The semi-auto and manual drains are both fitted, so you can drain manually or let the semi-auto function purge when pressure drops. If you need lubrication downstream, order the matching GAFC400-15 combination instead, as this unit does not add oil. The 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 (1/2" 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 GAFC400-15 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR40015S FAQ
The GAFR40015S is a filter and regulator with a 1/2in port, working pressure 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, 100 cc drain bowl, and 880 g weight. It has a 40 um element, PC bowl, semi-auto and manual drains, and a fitted circular gauge.
The GAFR40015S combines both functions in one body, so it filters the air and regulates the pressure in a single unit. A GAF filter only removes contaminants, while a GAR regulator only controls pressure. This combined design saves space and reduces potential leak points compared to using two separate parts.
