Airtac B52-GAFR Copper-Free Air Preparation Unit B52-GAFR30008ASJN
The AirTAC Airtac B52-GAFR Copper-Free Air Preparation Unit B52-GAFR30008ASJN 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-GAFR30008ASJN
The GAFR30008ASJN is a filter and regulator combined into a single body, so it cleans incoming air and sets a steady outlet pressure without needing a separate filter and regulator pair. This 1/4in port unit weighs 500 g and works across 0.15-0.9 MPa (20-130 psi), with a 40 um element trapping solid particles.
The diversion structure spins the air to separate liquid water and solids into the 60 cc drain bowl, while the balanced regulator holds the set pressure as supply varies. Since this model has no gauge, the 1/8in gauge connection is ready for adding one later if needed.

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-GAFR30008ASJN Is Used
Precision jig clamping
Feed a single fixture or clamping cylinder on a small assembly station, where the automatic drain keeps the 60 cc bowl from filling during long shifts.
Bench test rigs
Supply a regulated air supply to a benchtop test setup with a 1/4in port, relying on the balanced regulator to keep the outlet stable as shop pressure fluctuates.
Light automation cells
Power a compact pick-and-place unit or a small indexing table, using the 40 um element to protect sensitive valves from particle wear.
Is the Airtac B52-GAFR Copper-Free Air Preparation Unit B52-GAFR30008ASJN the Right Air-Prep Unit?
Choose the GAFR300 body for a 1/4in port with a 60 cc condensate bowl and a flow curve plotted to 3500 L/min at 0.7 MPa inlet. The automatic drain (A) suits unattended lines, while the missing bracket (J) means you plan a panel mount or use an existing bracket. With no gauge fitted, operators cannot read the set pressure without adding one to the 1/8in connection. The 40 um element handles general shop air, and the PT thread matches common local fittings. If oil is needed downstream, order the matching GAFC300-08 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 (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-GAFR30008ASJN FAQ
The GAFR30008ASJN is a filter and regulator with a 1/4in port, working range 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 60 cc drain bowl, and 500 g weight. It has a 40 um element and an automatic drain.
The J code means the mounting bracket is omitted for panel-mount or existing bracket setups, and the N code means no gauge is supplied. The 1/8in gauge connection is available if you add a gauge later, but without one you cannot read the outlet pressure directly.
