Airtac GAFR Adjustable Filter Regulator GAFR600C20S
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C20S 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 GAFR600C20S
The GAFR600C20S is a filter and regulator combined into a single body, handling both filtration and pressure control for large pneumatic systems. This model uses a 3/4in port, a 205 cc metal condensate bowl, and weighs 1880 g, placing it at the top of the GAFR size range.
It delivers a regulated output from 0.15 to 0.9 MPa (20-130 psi) with a 40 um filter element. The metal bowl is the only option for this body size, and the unit comes with a circular gauge showing MPa/psi. The integrated design replaces separate filter and regulator units, reducing potential leak points and saving space on the machine frame.

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 GAFR600C20S Is Used
Machine Header Supply
Feed a main air header for a multi-station assembly machine where several actuators and valves draw air simultaneously. The 3/4in port and high flow envelope keep pressure stable across the line.
Large Conveyor System
Supply a long conveyor line with multiple pneumatic stops and diverters. The 205 cc bowl handles condensate from high humidity plant air, and the included bracket mounts the heavy unit securely to the frame.
Central Prep for Precision Tools
Protect precision pneumatic tools and gauges by filtering to 40 um and regulating pressure at a central point. The balanced regulator holds the set pressure as supply fluctuates, keeping tool performance consistent.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C20S the Right Air-Prep Unit?
Choose this GAFR600 body when your line needs the highest flow capacity, with a flow curve plotted to 12000 L/min at 0.7 MPa inlet. The 3/4in port suits main headers feeding multiple stations, and the 205 cc drain bowl holds far more condensate than smaller bodies, meaning less frequent draining. The metal bowl is standard for this size, and the semi-auto plus manual drain gives you both automatic purging and a manual override. The included mounting bracket secures the 1880 g unit firmly to a frame or panel. The 40 um element handles general shop air; select the W option for 5 um filtration if you have sensitive valves downstream. The PT thread comes with an MPa/psi gauge scale, matching most local installations. If your process needs lubrication after this point, order the matching GAFC600-20 combination instead, which adds a lubricator. A 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan your inlet pressure near the maximum to achieve the highest setpoint.
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 GAFR600C20S FAQ
The GAFR600C20S is a filter and regulator with a 3/4in port. The pressure range is 0.15-0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C. It has a 205 cc metal drain bowl and weighs 1880 g.
The GAFR600 body is only available with a metal bowl. This is a design choice for the largest size in the series, likely for durability in high-flow industrial environments. The common specification of 1.0 MPa max pressure and -5 to 70 C temperature range applies, but confirm compatibility with your specific chemicals or impact conditions.
