Airtac GAFR Adjustable Filter Regulator GAFR500C20SW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR500C20SW 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 GAFR500C20SW
The GAFR500C20SW is a filter & regulator that combines a diversion-type air filter and a balanced pressure regulator inside a single metal-bodied unit. It handles a 3/4in port and delivers a regulated output from 0.15 to 0.9 MPa (20-130 psi), with a 5 um element for finer particle removal.
This 950 g body sits in the upper-middle size class, with a 108 cc condensate bowl that requires less frequent draining than smaller GAFR units. The pressed-in self-locking knob holds the set pressure steady against vibration, and the circular gauge with MPa/psi scale is fitted for direct reading.

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 GAFR500C20SW Is Used
Machine tool coolant systems
Feed a 3/4in line supplying coolant valves and cylinders on a CNC lathe, where the 5 um element protects precision spool valves from fine swarf particles.
Mid-size conveyor drives
Regulate air for a 10-meter conveyor with multiple air motors and tensioning cylinders, using the 108 cc bowl to handle condensate over a full shift.
Assembly station headers
Supply a central header for a multi-station assembly bench with pneumatic presses and screwdrivers, where steady pressure from the balanced regulator keeps cycle times consistent.
Is the Airtac GAFR Adjustable Filter Regulator GAFR500C20SW the Right Air-Prep Unit?
Choose the GAFR500 when you need a 3/4in port and a flow envelope plotted to 8000 L/min at 0.7 MPa inlet; step down to the GAFR400 (3/8in or 1/2in, 100 cc bowl) for lighter lines, or up to the GAFR600 (1in, 205 cc bowl) for a machine header. The metal bowl (C) suits demanding environments, and the 5 um element (W) traps finer particles than the standard 40 um. This model keeps the mounting bracket, has both semi-auto and manual drains fitted, and uses PT threads with an MPa/psi gauge scale. If oil is needed downstream, order the GAFC500-20 combination instead. 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 (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 GAFR500C20SW FAQ
Working pressure range is 0.15-0.9 MPa (20-130 psi), max pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -5 to 70 C. The drain bowl holds 108 cc and the unit weighs 950 g with a 3/4in port.
The metal bowl is a build choice for the condensate chamber; it is the only bowl option on the GAFR500C20SW. The common specifications (1.0 MPa max, -5 to 70 C) are identical to PC or nylon bowls, so confirm compatibility with your specific fluids or cleaning agents.
