Airtac GAFR Adjustable Filter Regulator GAFR50020SW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR50020SW 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 3/4" 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 GAFR50020SW
The GAFR50020SW is a filter and regulator combined in a single body, handling both filtration and pressure control without a separate filter unit. It serves a 3/4in port line, operates from 0.15-0.9 MPa (20-130 psi), and uses a 5 um element to catch fine particles.
The diversion structure spins incoming air to separate liquid water and solid debris into the 108 cc drain bowl, while the balanced regulator keeps the outlet steady. Weighing 950 g, this unit suits a machine header or multi-station line where a compact, integrated solution reduces potential leak points.

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 GAFR50020SW Is Used
Machine header supply
Feed a 3/4in header serving multiple pneumatic actuators on a production machine, with the 5 um element protecting sensitive valves from fine wear particles.
Instrument air prep
Prepare air for precision measurement or control instruments where the 5 um filtration removes fine solids that could clog orifices or affect readings.
Multi-station conveyor line
Regulate air for a conveyor system with several workstations, using the 108 cc bowl to handle condensate over longer shifts before manual draining.
Is the Airtac GAFR Adjustable Filter Regulator GAFR50020SW the Right Air-Prep Unit?
Choose the GAFR500 body for 3/4in port applications needing a flow envelope plotted to 8000 L/min at 0.7 MPa inlet. The PC bowl suits general industrial use; the included bracket simplifies mounting on a frame or panel. The 5 um element traps finer particles than the standard 40 um, ideal for precision valves or instrument air, though it requires more frequent service.
This model has a semi-auto drain plus manual drain, both fitted, and a circular gauge with MPa/psi scale. The standard pressure type covers 0.15-0.9 MPa (20-130 psi); if you need lubrication downstream, order the matching GAFC500-20 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 (3/4" 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 108 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 950 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 GAFC500-20 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR50020SW 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 108 cc and the unit weighs 950 g. It has a 3/4in port and a 5 um element.
The 5 um element traps much finer particles than the standard 40 um, making it suitable for precision valves or instrument air. The trade-off is that the finer element will load with contaminants faster, so it needs more frequent inspection and replacement.
