The AirTAC GFR30015MLJF2WGK 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR30015MLJF2WGK is a 300-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1/2 (BSPP) port, a 5 um filter element for finer filtration than the 40 um standard, a manual drain for the polycarbonate bowl, a low-pressure regulator type, an embedded square gauge scaled in psi, and a built-in reverse (check) valve. It ships without a mounting bracket.
This is a genuine AirTAC part from the GFR300 series, one of four sizes (200/300/400/600) spanning the GFR line, with port, thread (PT standard, G and NPT as order options), drain type, filter grade, gauge scale and bracket choices configurable per code. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures against 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.
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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.

On a fixture-clamping manifold that must run well below normal line pressure, the low-pressure regulator type gives finer control in the lower band, while the 5 um element keeps dirt out of the clamping cylinders and the check valve holds the circuit if upstream supply dips.
Feeding the cylinder bank on a carton-forming or case-sealing conveyor, this unit filters condensed water and fine particulate from the shop air, holds a steady regulated pressure for consistent stroke speed, and its manual drain is bled during shift checks.
At a workbench drop feeding impact tools or a small pneumatic press, the G1/2 port matches the main header, the 5 um element protects tool internals, the psi-scaled square gauge gives a direct pressure readout, and the reverse valve prevents downstream backflow.
Size 300 with a G1/2 port suits lines where the 1/4 to 3/8 step is too small; step up to 400 or 600 for larger ports and higher flow demand, or down to 200 for compact circuits. The 5 um element (code W) is the right pick when downstream valves and cylinders need finer protection than the 40 um standard. The manual drain needs periodic bleeding by an operator, unlike the automatic or differential-pressure options. The square gauge here reads in psi; MPa and bar scales are available, and an external round gauge is optional. Thread is G (BSPP) in this code; PT is the standard and NPT is an order option. A bracket is omitted with the J code, so plan mounting accordingly.
One honest note: flow for this series is published as curves, not a single rating, and the exact adjustment range of the low-pressure type is not in our published data. Ask us to confirm sizing and the regulator range 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 GFR series as curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Tell us your application and we will confirm the flow curve and sizing from the datasheet on request before you order.
The M code in the model means the polycarbonate bowl drains by hand, so an operator opens it periodically instead of relying on an automatic or differential-pressure drain. The L code sets the regulator as the low-pressure type, intended for circuits regulated well below standard line pressure; its exact adjustment range is not in our published data, so confirm it with us on request.
