The AirTAC Airtac GAFR Filter & Regulators GAFR40015AST 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 GAFR40015AST is an AirTAC filter and regulator combined in a single body with a 1/2" port. The same housing first spins the incoming air so water and solid particles fall into the bowl, then a balanced mechanism sets a steady outlet pressure anywhere from 0.15 to 0.9 MPa (20-130 psi). A 40 um element is fitted as the standard grade, and there is no lubricator anywhere in this unit. Because it is one body instead of a separate filter plus a separate regulator, you seal fewer joints and occupy less rail width on the preparation wall. An automatic drain empties the 100 cc condensate bowl on its own, which suits lines that run unattended, and the included mounting bracket lets the 880 g mass sit on a panel rather than hang from the tubing.

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.

A 1/2" port carries the volume a machining centre drawbar or fixture clamp circuit consumes, while the balanced regulator keeps clamp force consistent as shop supply wanders during the day.
Packaging machinery runs long shifts with nobody watching the drains, so the automatic condensate drain on this model protects cylinders and valves without a daily walk-round.
On a multi-station floor, one filtered and regulated drop per bench keeps torque tools steady, and the included bracket fixes the 880 g unit firmly to each station panel.
This code pairs the GAFR400 body with a 1/2" port, automatic drain, standard pressure type and NPT threads, so the supplied circular gauge reads in psi and bar. The transparent PC bowl is the standard build; metal (C) or nylon (N) versions can be ordered instead, and compatibility should be confirmed with the datasheet if the surroundings involve solvents or heavy impacts. If a setting above 0.9 MPa could ever be required, this is the correct type, since the L variant tops out at 0.4 MPa (20-58 psi). A 5 um (W) element is available when finer particle capture matters more than service intervals. Should the circuit also need oil mist, order the matching GAFC400-15 combination rather than expecting lubrication from this part. For sizing, its flow curve is plotted to 7000 L/min at 0.7 MPa inlet, a 2x step over the 3500 L/min envelope of the smaller GAFR300.
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 filters and regulates compressed air in one 1/2" ported body. The standard type regulates from 0.15 to 0.9 MPa (20-130 psi), with a maximum working pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). Rated temperature is -5 to 70 C and the unit must not freeze. The condensate bowl holds 100 cc and the complete unit weighs 880 g.
The T selects NPT threads instead of the default PT, and it also fixes the gauge scale: an NPT version reads in psi and bar, whereas the blank PT version reads in MPa and psi. Pick the scale your operators actually check, because the code changes both the thread and the dial together.
