The AirTAC Airtac GAFR Filter & Regulators GAFR600C25ST 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" 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 GAFR600C25ST puts AirTAC's biggest filter-regulator stage into one machined body: incoming air is spun through a diversion structure so liquid water and solid grain settle into the 205 cc drain bowl, and a balanced, self-locking regulator then holds the outlet anywhere from 0.15 to 0.9 MPa (20-130 psi). The standard 40 um element handles general plant air, and because this is a filter plus regulator unit only, there is no lubricator stage anywhere in it. This model has 1 inch NPT ports, so its supplied circular gauge is scaled in psi and bar for operators who read imperial. At 1880 g it is far too heavy to be carried by the tubing, and the included mounting bracket should be bolted to a panel or frame. Its plotted flow curve at 0.7 MPa inlet reaches 12000 L/min, and the 1.5 MPa (215 psi) proof rating of every GAFR body applies here as a burst-test margin rather than a working figure.

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 GAFC600-25 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 inch inlet suits the main distribution header of a large machine, where one filtered and regulated supply point feeds every downstream branch.
Several valve-and-cylinder stations can draw from a single regulated drop, with the metal bowl and 205 cc reservoir coping with heavy condensate loads.
High-cycle packaging machinery with large actuators needs the steady outlet pressure this body's balanced regulator maintains through each shift.
Body 600 is the ceiling of the GAFR range, and it removes two decisions for you: the bowl is metal only and the pressure type is standard only, covering 0.15-0.9 MPa (20-130 psi). What you do choose is the port, and a 3/4in line should step down to the GAFR500C20S, which shares this construction at a smaller scale. The blank drain position on this SKU includes both a semi-automatic drain and a manual drain; if the line runs unattended or carries wet air, order the A version instead. Omitting the gauge or the mounting bracket (codes N and J) is possible on request, and the blank element position means the coarse 40 um grade, with W available for 5 um. If the machine downstream also needs lubrication, the matching GAFC combination is the correct upgrade, since this unit filters and regulates but never adds oil. On capacity, the plotted flow curve here of 12000 L/min at 0.7 MPa inlet is 1.5x the 8000 L/min of a GAFR500, so moving up one body size from 3/4in buys half again the sizing envelope.
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 GAFC600-25 combination; do not expect an oil mist from this unit.
It is a filter and regulator in one body with 1 inch NPT ports. Pressure range is 0.15-0.9 MPa (20-130 psi) on the standard type, maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). The rated temperature range is -5 to 70 C. The drain bowl holds 205 cc, the unit weighs 1880 g, the element grade is 40 um, the bowl is metal, and both a semi-automatic and a manual drain are fitted.
The final letter T in the ordering code selects NPT ports, and in this series the thread code also fixes the gauge scale: NPT models carry a gauge reading psi and bar. Ordering with a blank thread position gives PT ports with an MPa/psi scale, while G gives G threads and a bar/MPa scale, so pick the scale your operators already read.
