The AirTAC Airtac B52-GAFR Copper-Free Air Preparation Unit B52-GAFR20008SW 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.
The GAFR20008SW is a filter and regulator combined into a single body, saving space and reducing potential leak points compared to separate units. It handles a 1/4in port with a standard pressure range of 0.15-0.9 MPa (20-130 psi) and uses a 5 um element for finer filtration.
This compact 290 g unit includes a circular gauge with an MPa/psi scale and a mounting bracket. Its 25 cc condensate bowl and semi-auto plus manual drain make it a straightforward choice for small automated systems needing clean, regulated air.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. The fitted circular gauge reads in MPa / psi, set by the PT thread code. This unit filters and regulates only; it does not add lubrication.

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 GAFCB52-20 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.

Feed a single pneumatic clamp or small positioning jig on an assembly bench with clean, regulated air at a steady pressure.
Provide filtered air to a lab instrument or test rig that needs consistent pressure and finer 5 um particle removal.
Supply a workshop air tool or blow-off station where a compact, reliable filter-regulator is needed to protect the equipment.
Choose the GAFR200 body for light-duty circuits with 1/4in porting; the GAFR300 offers a larger 60 cc bowl and a flow envelope plotted to 3500 L/min at 0.7 MPa inlet if you need more capacity. The PC bowl is the standard build, and the 5 um element suits precision valves or instrument air, though it will need more frequent service than a 40 um unit. This model includes the mounting bracket and a fitted gauge, with a semi-auto plus manual drain for flexible condensate removal. If your line needs lubrication downstream, order the matching GAFC200-08 combination instead, as this unit does not add oil. A 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range.
Quick checklist
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 GAFCB52-20 combination; do not expect an oil mist from this unit.
It is a filter & regulator with a 1/4in port, a working pressure range of 0.15-0.9 MPa (20-130 psi), a max pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, the drain bowl holds 25 cc, and the unit weighs 290 g.
The 5 um element traps much finer particles than the standard 40 um grade, making it suitable for precision valves or instrument air. The trade-off is that the finer element will load up faster and require more frequent replacement.
