The AirTAC GFR30015MLJC2W AirTAC Filter Regulator PT1/2 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 GFR30015MLJC2W 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 PT1/2 port, a 5 um filter element (the finer of the two catalogue grades), a manual drain for the PC bowl, the low-pressure regulator type, and a round external gauge scaled in psi. No mounting bracket is fitted and no reverse/check valve is included.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with a choice of drain type, 40 um or 5 um filtration, gauge style and scale, G or NPT thread options, and bracket variants. 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.
| 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). |
| 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. |
| (blank) | PT 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.

Feeds spray guns and atomising air on a finishing line, where the 5 um element helps keep water and particles out of the finish and the low-pressure regulator type suits circuits run at reduced working pressure.
Supplies cleaned, regulated air to cylinders and actuators on a cartoning or wrapping conveyor, with the manual drain emptied during scheduled changeover stops.
Conditions bench air for lab apparatus and test rigs that need a stable, low-pressure regulated feed, with the round psi gauge read directly at the point of use.
Step up through the size range (200/300/400/600) to match the port and flow your line needs; the 300 size with a 1/2 in PT port suits circuits fed at 1/2 in. Choose the drain to match maintenance practice: manual (this unit, lowest regulated setting range), automatic, or the differential-pressure default. Pick the 5 um element (code W, as here) when downstream equipment needs finer filtration than the 40 um standard. Gauge style and scale are decodable: embedded square or external round, in MPa, psi or bar (this unit is round, psi). Thread is PT as standard with G (BSPP) and NPT as order options, and the J code here means no bracket is supplied.
Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing from 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 a number. Send us your application details and we will confirm the flow and sizing from the datasheet on request.
The M code means the PC bowl is emptied by hand rather than automatically, which suits lines with regular maintenance stops; automatic and differential-pressure drains are available as alternative codes. The W code selects the 5 um element instead of the 40 um standard, for finer protection of downstream equipment.
