Airtac GAFR Adjustable Filter Regulator GAFR600C20SNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C20SNK 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 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 GAFR600C20SNK
The GAFR600C20SNK is a filter and regulator combined into a single body, handling both air cleaning and pressure stabilization in one compact unit. This 3/4in model operates from 0.15 to 0.9 MPa (20-130 psi) and comes with a 40 um element, ready for high-flow pneumatic systems.
Its metal bowl and 205 cc condensate capacity suit demanding industrial environments, while the included mounting bracket ensures stable installation. The unit also features a reverse-flow valve fitted as standard, making it a complete solution for large-scale air preparation.

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 GAFR600 is 1/4" if you add one. This unit filters and regulates only; it does not add lubrication.

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 GAFR600C20SNK Is Used
Machine Headers
Feed a central header supplying multiple pneumatic stations on a large assembly line, where consistent pressure and high flow are critical.
Heavy Presses
Protect large press actuators and cylinders from contaminated air while maintaining stable operating pressure for consistent cycle times.
Multi-Station Conveyors
Supply a long conveyor system with multiple diverters and stops, ensuring each station receives clean, regulated air for reliable operation.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C20SNK the Right Air-Prep Unit?
Choose the GAFR600 for heavy-duty applications requiring high flow, as its flow curve is plotted to 12000 L/min at 0.7 MPa inlet. This model includes the mounting bracket and a semi-auto plus manual drain, giving you flexibility in maintenance routines. The metal bowl is the only option for this size, and the 40 um element handles standard filtration needs.
The unit comes without a gauge, but the 1/4in gauge connection allows easy addition if needed. With a PT thread and standard pressure range, it integrates seamlessly into most industrial setups. If lubrication is required downstream, consider the matching GAFC600-20 combination instead. Remember that 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan your inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (3/4" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: Metal (C) only
- ✓ 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 205 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1880 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 GAFC600-20 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR600C20SNK FAQ
The GAFR600C20SNK operates from 0.15 to 0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works in temperatures from -5 to 70 C, has a 205 cc drain bowl, and weighs 1880 g.
