The AirTAC GFR30015ALJC1WT 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 GFR30015ALJC1WT is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration carries a 1/2 in NPT port, a 5 um filter element (code W), an automatic drain that ejects condensate without daily attention, and a round pressure gauge scaled in MPa. The L code marks the low-pressure regulator type, and no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the bowl on size 300 is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options across drain types (differential-pressure, automatic, manual), filter grades (40 um standard, 5 um optional), gauge styles and scales (MPa, psi, bar), threads (PT standard, G and NPT to order) and bracket choice. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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. |

| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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. |

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.

Filter and regulate the air feeding a bank of directional control valves on a packaging or assembly machine, keeping condensate and fine particles out of the valve seats while holding a set downstream pressure.
Supply filtered, regulated air to the cylinders that index, clamp and divert product along a conveyor line, with the automatic drain clearing collected condensate through continuous shifts.
Condition the shop-air feed to a CNC machining centre's pneumatic circuits - tool-change clamps, chip gates and air blasts - where the 5 um element protects the downstream components.
Every choice in GFR30015ALJC1WT is decodable from the code. Size 300 pairs with the 1/2 in NPT port; step up or down a size when your line needs a different port or more flow capacity. The 5 um element (code W) suits air feeding sensitive valves and instruments, while the 40 um standard element is the usual choice for general plant air. The automatic drain handles condensate continuously; manual and differential-pressure drains remain available in the family. The low-pressure regulator type is selected by the L code - its exact adjustment span is not published in the material we hold, so we confirm it on request. The gauge fitted here is the round type scaled in MPa (psi and bar scales exist), and this unit is supplied without a mounting bracket - order one if you panel-mount. Thread is NPT on this code; PT is the standard thread and G is also available. Because flow is published as curves, not a single rating, send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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 we do not quote one number here. Send us your required flow and working pressure and we will confirm sizing from the datasheet on request.
The W in the code specifies the 5 um filter element instead of the 40 um standard, for air feeding finer components, and the A specifies an automatic drain that ejects collected condensate on its own. Manual-drain and differential-pressure-drain versions are available in the same family if you prefer.
