The AirTAC GFR30015AJC2GK AirTAC Filter Regulator G1/2 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 GFR30015AJC2GK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This configuration has G1/2 ports, an automatic drain that ejects collected condensate without operator attention, standard 40 um filtration, a round gauge reading in psi, a reverse/check valve fitted, and no mounting bracket. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing). The bowl on this 300 size is polycarbonate (PC); only the 600 size uses aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and catalogue options include manual or differential-pressure drains, a 5 um filter element (code W), embedded square or external round gauges with MPa, psi or bar scales, PT, G (BSPP) or NPT threads, and a mounting bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

|---|---|
| 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. |

| C | Gauge shape: Round. 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. |
| G | G (BSPP) 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.

Feeding clean, pressure-stable air to spray guns in a paint booth: the 40 um element strips water and particulate that would spoil the finish, while the regulator holds one steady setting for consistent atomisation.
Supplying filtered, regulated air to pneumatic clamps on a machining cell so clamp force stays consistent part after part, with the fitted reverse valve blocking backflow toward the supply side.
Regulating air to cylinders and diverters along a packaging conveyor, with the automatic drain clearing collected condensate through long production runs without an operator visiting each station.
Choose the size by port and flow: this 300 unit carries G1/2 ports; step up to 400 or 600, or down to 200, as the flow demand of your line changes - we can confirm flow against the published curves before you order. Drain choice: automatic (this unit) clears condensate by itself; manual needs operator action; differential-pressure drains only when the pressure drop across the element is high enough. Filter grade: 40 um standard, 5 um (code W) for finer protection. Gauge: this unit has a round, psi-scaled gauge; embedded square gauges and MPa or bar scales are options. Thread: PT is the standard; G (BSPP, fitted here) and NPT are order options. Bracket: this configuration has no mounting bracket; bracketed versions exist as options. Because 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 flow for the GFR300 as curves, not a single rated number, so we do not quote a figure here. Send us your flow and pressure requirements and we will confirm the sizing from the datasheet on request.
This unit's code includes A for an automatic drain, which ejects collected condensate without operator attention. Manual (M) and differential-pressure (blank) drains are catalogue options in the same family. Note that the regulation range is split by drain type: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drains, and 0.05-0.9 MPa (7-130 psi) with a manual drain.
