The AirTAC GFR30010AJF2TK AirTAC Filter Regulator 3/8 in NPT 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 PT3/8" 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 GFR300-10 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/8 in NPT port, a 40 um filter element, an automatic drain that expels collected condensate without manual attention, an embedded square pressure gauge reading in psi, and a reverse/check valve fitted. The polycarbonate bowl suits non-freezing compressed air from -5 to 70 C, maximum inlet pressure is 1.0 MPa (145 psi), and the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi).
This is a genuine AirTAC part from the GFR300 series. GFR filter regulators are available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options across the series include manual or differential-pressure drains, a 5 um element (code W), G or NPT threads, alternative gauge scales, and bracket choices. 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.
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". 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. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 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. |
| K | Reverse-flow (reflux) valve fitted. |
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 at the point of use on a machine shop air drop, it dries and cleans the supply to the machining center's pneumatic valves and holds the set pressure steady as clamps and tool changers cycle through the shift.
Mounted on the frame of a bottling or carton-packing conveyor, it conditions the air feeding the case-sealing and pusher cylinders and lets the line technician set a consistent operating pressure for repeatable strokes.
Fitted ahead of the spray gun supply line in a paint finishing booth, it removes water and pipe scale that would otherwise blemish the finish and provides an adjusted, gauge-monitored pressure at each station.
Size and port set the capacity: this 300-size unit carries a 3/8 in NPT port, and stepping up to the 400 or 600 size gives a larger port for greater air demand. Drain choice matters in use: automatic (fitted here) suits unattended installations, while manual and differential-pressure drains are the other catalogue options. The standard element is 40 um; specify code W for 5 um when finer filtration is required. The embedded square gauge reads in psi, with MPa and bar scales available as alternatives. This code specifies NPT thread (PT is the standard thread; G and NPT are order options), no mounting bracket, and a reverse/check valve fitted. Flow is published as curves, not a single rating - 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes G-series flow data as curves rather than a single rated figure, so we do not quote a flow number here. Send us your application's air demand and operating pressure and we will confirm from the datasheet whether this 300-size unit with its 3/8 in NPT port is correctly sized before you order.
This unit carries drain code A, an automatic drain that expels collected condensate from the bowl without manual attention. The series also offers manual (M) and differential-pressure (blank) drains. Note that the regulation range differs by drain type: 0.15-0.9 MPa (20-130 psi) for automatic and differential-pressure drains, 0.05-0.9 MPa (7-130 psi) for manual drain, so check the drain code when ordering.
