The AirTAC Airtac GAFR Filter & Regulators GAFR40015ST 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 1/2" 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 GAFR40015ST is an AirTAC filter & regulator: a diversion-stage air filter and a balanced pressure regulator share one body, so a single panel unit replaces the pair of separate parts a filtered, regulated drop would otherwise need. Air enters, gets spun so liquid water and solid particles settle into the bowl, then leaves at a set pressure held steady as supply fluctuates. This model ports at 1/2 in with NPT threads, regulates across 0.15-0.9 MPa (20-130 psi), and carries the standard 40 um element.
Build details worth noting before you order: the body weighs 880 g, so it belongs on a bracket or panel rather than hanging off the tubing, and the mounting bracket ships with it. The single 100 cc condensate bowl drains semi-automatically, with a manual drain fitted as backup. A circular gauge comes installed and, because the T thread code was chosen, its scale reads psi/bar. Rated temperature span is -5 to 70 C. There is no lubricator here and only one bowl; if oil mist is wanted downstream, the GAFC400-15 combination on the same body and port is the upgrade path.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. The fitted circular gauge reads in psi / bar, set by the NPT 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 GAFC400-15 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.

Feeds cartoners and case packers that need clean air at a fixed pressure; the 40 um element stops grit reaching the machine's air cylinders while the regulator holds the set point through each cycle.
A 1/2 in regulated drop suits conveyor gates, stops and pusher cylinders, where pressure sag during a shift would cause misfires at the divert station.
Mounted on the bracket at a machine tool or assembly bench, it filters line water and solids into the 100 cc bowl and delivers a steady 0.15-0.9 MPa (20-130 psi) output to clamps and fixtures.
Port first: the 400 body takes a 1/2 in line and its flow curve is plotted to 7000 L/min at 0.7 MPa inlet, which is a sizing envelope rather than a rated figure. If your demand sits well under that, a 300-size unit still covers 1/2 in ports; if you are feeding a big header, look at the 500 or 600 body instead. The bowl code is blank on this SKU, so the bowl is polycarbonate; order C for metal or N for nylon when the install environment calls for a different material, and confirm compatibility for aggressive surroundings since the catalogue prints no chemical data. Drainage here is the blank option: semi-automatic drain plus a manual drain, both fitted. The S type sets the working band at 0.15-0.9 MPa (20-130 psi); if the machine will never exceed 0.4 MPa, an L suffix lowers the ceiling instead. Bracket included, gauge fitted, 40 um filtration, and the T code gives you NPT threads with a psi/bar gauge scale; add W for a 5 um element or K for a reverse-flow valve if the order needs them. Remember that 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 GAFC400-15 combination; do not expect an oil mist from this unit.
It is a 400-size AirTAC filter & regulator with a 1/2 in NPT port. Working range is 0.15-0.9 MPa (20-130 psi); maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). Temperature rating is -5 to 70 C. The condensate bowl holds 100 cc and the unit weighs 880 g. Filtration grade is 40 um, the drain is semi-auto plus manual, and the gauge reads psi/bar.
The T at the end of GAFR40015ST selects NPT thread ports. The thread code also fixes the gauge scale on this series: PT ships with an MPa/psi dial, G with bar/MPa, and T with psi/bar. Choose the code matching the scale your operators already read, since mixing a bar dial into a psi-only workshop invites misreading of the set pressure.
