Airtac B52-GAFR Copper-Free Air Preparation Unit B52-GAFR30008L
The AirTAC Airtac B52-GAFR Copper-Free Air Preparation Unit B52-GAFR30008L 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 See datasheet 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 B52-GAFR Copper-Free Air Preparation Unit B52-GAFR30008L
The GAFR30008L is a filter and regulator combined into a single body, cleaning incoming air and holding a steady outlet pressure without a separate filter-regulator pair. This lower-pressure version works from 0.15 to 0.4 MPa (20-58 psi) and comes with a 40 um element, a 60 cc condensate bowl, and a 500 g mass that suits compact machine builds.
Its diversion structure spins the airflow to drop liquid water and solid particles into the bowl before regulation, while the balanced, self-locking knob resists set-pressure drift from vibration. The circular gauge with clip and magnifier reads MPa/psi, and the mounting bracket is included for panel or frame installation.

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 GAFCB52-30 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 B52-GAFR Copper-Free Air Preparation Unit B52-GAFR30008L Is Used
Light Assembly Fixtures
Feed a single pneumatic clamp or a small indexing table on a benchtop assembly station, where the lower 0.4 MPa ceiling protects delicate workpieces from over-force.
Test Benches
Supply a regulated air signal to pressure gauges or leak-test fixtures on a lab bench, where the balanced regulator holds the setpoint as shop pressure fluctuates.
Paint Spray Booths
Run a low-pressure air line to a touch-up spray gun or blow-off nozzle, where the 40 um element traps particulates and the 60 cc bowl collects water before it reaches the tool.
Is the Airtac B52-GAFR Copper-Free Air Preparation Unit B52-GAFR30008L the Right Air-Prep Unit?
Choose the GAFR30008L when your circuit needs a lower regulated ceiling of 0.4 MPa, such as for light actuation or sensitive pneumatic controls. The 1/4in port and 500 g weight place it in the GAFR300 size class, with a flow curve plotted to 3500 L/min at 0.7 MPa inlet; the 60 cc drain bowl is the service driver, and the semi-auto plus manual drain lets you empty it on a schedule or automatically when pressure drops. The PC bowl is the standard build, the PT thread sets the gauge scale to MPa/psi, and the included bracket saves rail space; if you need finer filtration, the W option swaps the 40 um element for 5 um. For lines that require oil downstream, order the matching GAFC300-08 combination instead, since this unit does not lubricate. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above this unit's 0.4 MPa top setting, so plan your inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (See datasheet here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC, Metal, Nylon
- ✓ 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 See datasheet bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the See datasheet 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 GAFCB52-30 combination; do not expect an oil mist from this unit.
Airtac B52-GAFR Copper-Free Air Preparation Unit B52-GAFR30008L FAQ
The GAFR30008L is a filter & regulator with a 1/4in port, a pressure range of 0.15-0.4 MPa (20-58 psi), a max pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, has a 40 um element, a 60 cc drain bowl, and weighs 500 g. The gauge is fitted with an MPa/psi scale, and the mounting bracket is included.
The L type limits the regulated output to a maximum of 0.4 MPa (58 psi), whereas the standard S type reaches up to 0.9 MPa (130 psi). This makes the L version suitable for circuits that must never exceed a low pressure, but it cannot supply higher pressures if the machine's needs change. The body, port, bowl capacity, and weight remain the same as the standard GAFR300.
