The AirTAC GFR30015ANT AirTAC Filter Regulator NPT1/2 is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/2" ports, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR30015ANT is a 300-size filter regulator that removes water and particulate from compressed air and reduces pressure to the set point in a single body. This configuration has a 1/2 in NPT port, an automatic drain that discharges collected condensate without operator attention, a 40 um standard filter element, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and no gauge is fitted.
This is a genuine AirTAC part. The GFR300 series is one of four sizes (200, 300, 400, 600) with ports from 1/8 to 1 in, PT as the standard thread and G or NPT to order, a choice of automatic, manual or differential-pressure drains, and a 5 um element option (code W). Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeding a pneumatic press cylinder with cleaned, regulated air: the 40 um element strips water and debris before the valve stack, while the regulator holds a stable set point so press stroke force stays repeatable across shifts.
Point-of-use preparation for conveyor and carton-sealing cylinders on a packaging line. The automatic drain keeps the polycarbonate bowl clear of condensate on lines that run unattended, and the 1/2 in NPT port suits a main machine drop.
A dedicated drop at an assembly cell where air tools and clamping fixtures share one supply. The filter regulator gives each cell its own pressure setting independent of the header, and the included bracket mounts the unit at the take-off point.
Step through the size and port range (200 to 600, 1/8 to 1 in) against the air your line consumes - flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering. Drain type is a real choice on this family: automatic (this unit) empties the bowl on its own, manual needs operator action, and differential-pressure drains on pressure drop. The 40 um element is standard; specify 5 um (code W) where finer filtration is needed. This model carries no gauge - a square or round gauge with MPa, psi or bar scale can be ordered. Thread is NPT here; PT is the standard and G is also available. A mounting bracket is included.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR300 series as curves rather than a single rated figure, so we do not quote a number here. Send us your operating pressure and air demand and we will confirm the flow from the datasheet before you order.
This model carries drain code A, the automatic drain, which discharges collected condensate from the bowl without operator action - the practical choice for unattended or hard-to-reach installations. Manual (code M) and differential-pressure (blank) drains are alternative order options on the GFR300 series.
