The AirTAC GFR30015ALJC2WT AirTAC Filter Regulator NPT1/2 is a genuine G-series filter regulator: water separation, 5 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 GFR30015ALJC2WT is a GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with 1/2 in NPT ports, a 5 um filter element (code W), an automatic drain, the low-pressure regulator type, a round gauge with a psi scale, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in, PT as the standard thread and G or NPT to order, a choice of differential-pressure, automatic or manual drains, and 40 um standard or 5 um optional filtration. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet numbers 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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.

Filtered, regulated air feeding clamp cylinders on a CNC fixture, with the low-pressure regulator type suiting circuits that hold workpieces at reduced pressure and the 5 um element protecting the clamping valves.
A 5 um element ahead of directional valves and actuators on a packaging machine, with the automatic drain keeping the bowl clear through unattended shifts and the psi gauge giving operators a direct line readout.
Clean, regulated air to instruments and test rigs where the round psi-scaled gauge gives a direct readout, the 5 um grade protects sensitive components, and the low-pressure type matches reduced-pressure bench circuits.
Within GFR300 you step the port (1/4 in on the -08, 3/8 in on the -10, 1/2 in on the -15) against the air your line consumes; because flow is published as curves and not a single rating, send us your demand and we will confirm the right size before you order. Drain type is a real choice: automatic empties the bowl without operator attention, manual relies on a routine drain, and differential-pressure drains as the element loads up - this unit is automatic. Element grade is 40 um standard or 5 um (this unit, code W) where finer protection matters. The gauge scale can be MPa, psi or bar (this unit reads psi), the thread is PT standard with G and NPT as order options (this unit is NPT), and the bracket is optional (omitted here).
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 as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the datasheet curve and sizing for your application before you order.
The W code selects the 5 um element instead of the 40 um standard, giving finer protection for downstream valves and actuators, and the A code fits the automatic drain, which removes collected condensate without manual attention. Both are standard catalogue options on the GFR300.
