The AirTAC GFR30015AJNT 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 GFR30015AJNT is a size-300 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 1/2 in NPT port, the standard 40 um filter element, and an automatic drain that expels collected condensate from the PC bowl without manual attention. No gauge is fitted (code N) and no mounting bracket is included, so add a gauge separately if local pressure indication is needed.
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for your application before ordering.

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.
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| 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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Installed on a 1/2 in branch line feeding impact wrenches and air ratchets at an assembly plant, cleaning the supply and holding a steady working pressure for the tool circuit.
Mounted ahead of the cylinders and air cylinders on a carton-forming and sealing conveyor, filtering condensate from the header air and regulating it to the pressure the actuators were set up for.
Used as the conditioning and regulation point on a dedicated drop feeding valve manifolds and process actuators on an automated production machine, with the automatic drain keeping the bowl clear between service visits.
Choose the size and port step against the air demand of the circuit: this unit is size 300 with a 1/2 in NPT port. Drain type is a real decision: this unit has an automatic drain (code A), which suits unattended installations; manual and differential-pressure drains are available in the same series. Filter grade is the standard 40 um element; a 5 um element (code W) is offered where finer filtration is required. Thread here is NPT; PT is the catalogue standard and G (BSPP) is also an order option. Brackets are optional (this unit has none, code J) and a gauge with MPa, psi or bar scale can be ordered if needed.
Because flow for the GFR series is published as curves and not as a single rated figure, ask us to confirm sizing against your application before ordering.
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 GFR series as curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Tell us your application and required flow and we will confirm sizing from the datasheet on request before you order.
The N in the code GFR30015AJNT means no gauge is fitted. A gauge is an order option on GFR units, with an embedded square gauge or an external round gauge in MPa, psi or bar scale, so add one if you want downstream pressure indicated at the unit.
