Airtac GAFR Adjustable Filter Regulator GAFR50020SNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR50020SNW 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 GAFR50020SNW
The GAFR50020SNW is a filter and regulator combined into one body, handling both air preparation tasks without a separate filter and regulator pair. This 3/4in unit operates from 0.15 to 0.9 MPa (20-130 psi) and comes with a 5 um element that traps finer particles for sensitive downstream equipment.
Its 108 cc condensate bowl collects water and solids separated by the internal diversion structure, while the 950 g body with included mounting bracket suits fixed installations. The balanced regulator mechanism holds the set outlet pressure steady as supply pressure varies, and the pressed-in self-locking 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 GAFR500 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 GAFC500-20 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 GAFR50020SNW Is Used
Machine Header Supply
Feed a multi-station assembly machine header where several actuators and valves draw from one 3/4in line, with the 5 um element protecting precision components.
Conveyor System Air
Supply a long conveyor line with multiple air cylinders, using the 108 cc bowl to handle condensate from a wet compressor before it reaches controls.
Instrument Air Feed
Provide filtered, regulated air to a bank of I/P transducers or flow meters that need the finer 5 um filtration and stable pressure from the balanced regulator.
Is the Airtac GAFR Adjustable Filter Regulator GAFR50020SNW the Right Air-Prep Unit?
Choose the GAFR500 for 3/4in lines needing up to 8000 L/min at 0.7 MPa inlet, stepping down from the GAFR600's 12000 L/min envelope or up from the GAFR400's 7000 L/min. The PC bowl suits standard shop air, while the 5 um element handles precision valves or instrument air at the cost of more frequent service. This model ships with both semi-auto and manual drains, includes the mounting bracket, and omits the gauge - the 1/4in gauge connection is ready for a field-installed unit. The PT thread carries an MPa/psi scale, and no reverse-flow valve is fitted. If lubrication is needed downstream, order the matching GAFC500-20 combination instead. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated 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 GAFR50020SNW FAQ
The GAFR50020SNW is a filter & regulator with a 3/4in port, working pressure range of 0.15-0.9 MPa (20-130 psi), maximum pressure of 1.0 MPa (145 psi), and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 108 cc and the unit weighs 950 g.
The N code means no gauge is supplied, so the set pressure cannot be read directly on the unit. The 1/4in gauge connection is present, allowing you to add an AirTAC gauge later if needed. This is useful for installations where a remote or panel-mounted gauge is preferred.
