The AirTAC GFR30015LJF2WGK AirTAC Filter Regulator, G1/2, 5 um 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 differential-pressure 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 GFR30015LJF2WGK is an AirTAC GFR300 low-pressure filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built with G1/2 ports, a 5 um filter element (the fine W grade, versus the 40 um standard), a differential-pressure drain on the PC bowl, an embedded square gauge scaled in psi, and a reverse/check valve fitted. It ships without a mounting bracket, so plan your panel or manifold fixing accordingly.
This is a genuine AirTAC part from the GFR300 size class. The G-series filter-regulator line spans sizes 200 to 600 with port options from 1/8 to 1 inch, filter grades of 40 um standard or 5 um optional, drain choices, gauge styles and scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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. 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.

| (blank) | Drain: Differential-pressure 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). |
| F | Gauge shape: Square. 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. |
| 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-controlled air to a cartoning or wrapping line's cylinders and actuators, with the 5 um element guarding the machine's control valves from water and fine debris.
Regulating supply to a fixture-clamping or hold-down circuit that runs at reduced pressure, where the low-pressure regulator type and check valve hold the set condition downstream.
Conditioning shop air for a test rig or laboratory bench where finer 5 um filtration and a psi-scaled gauge give operators a clean, readable, stable supply at the bench.
Size and port step up with required flow: this unit is size 300 with G1/2 ports, so check it against your line's air demand before ordering. The 5 um element here is the finer option; the 40 um standard grade suits general-duty circuits, while 5 um protects sensitive valves and instruments. Drain is differential-pressure on this model; automatic (A) and manual (M) drains are available in the family if your duty cycle needs them. The embedded square gauge reads in psi here; MPa and bar scales and an external round gauge are alternatives. Thread is G (BSPP); PT is the catalogue standard and NPT is also orderable. A mounting bracket is optional (this unit omits it). Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before you order.
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 GFR series as curves, not as a single rated figure, so there is no one number we can quote. Tell us your application and required flow, and we will confirm the datasheet curve figures for this unit on request before you order.
The W in the code GFR30015LJF2WGK selects the optional 5 um filter grade instead of the 40 um standard, for finer protection of downstream components. The K selects a reverse/check valve fitted at the outlet. Both are order options; the 40 um grade and no-valve versions are available if your circuit does not need them.
