The AirTAC GFR30015MLJC2T AirTAC Filter Regulator NPT 1/2 in is a genuine G-series filter regulator: water separation, 40 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 GFR30015MLJC2T is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single 300-size body. This configuration is fitted with 1/2 in NPT ports, a manual drain bowl, the standard 40 um filter element and a low-pressure regulator type, so it suits circuits that need conditioned air held at a set pressure below the standard regulator span. The external round gauge is scaled in psi, the bowl is polycarbonate, and no mounting bracket or reverse/check valve is included in this code.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT thread, manual, automatic or differential-pressure drains, 40 um or 5 um (code W) filtration, gauge and scale options, and bracket variants. Flow for this model is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application before you order.

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. |
| (blank) | Filtering grade 40 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.

Conditioned, regulated air feeding clamping fixtures that must hold at a set low pressure, with the 40 um element keeping scale and pipe debris out of the clamp cylinders.
Filtered and regulated air supply to sealing jaws and actuated guides on a packaging line, where the manual drain lets operators bleed accumulated condensate at shift start.
A bench-mounted supply point for pneumatic test rigs running at reduced pressure, with the round psi gauge giving a direct, readable setpoint in US units.
Start with the size and port: this unit is size 300 with 1/2 in NPT ports; step up or down through sizes 200, 300, 400 and 600 as your line's flow demand grows, since larger sizes carry larger ports and more flow capacity. Because this code is the low-pressure regulator type, confirm your working pressure band with us first - the exact adjustment range for the low-pressure variant is not published in the standard table, and we will verify it against the datasheet. Choose the drain to match maintenance access: this unit has a manual drain, so someone must bleed the bowl; automatic or differential-pressure drains are available on other codes. The standard element is 40 um; specify code W for 5 um finer filtration. Gauge scale is selectable (MPa, psi or bar) - this code carries a round psi gauge. Thread is NPT here; PT and G are orderable options. A mounting bracket can be added on bracket-equipped codes; this one is code J (no bracket).
Flow is published as curves, not a single rating, so 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, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow curve and sizing from the datasheet before you order.
The M in the code specifies a manual drain bowl: an operator opens the drain to release collected condensate. If you cannot rely on regular draining, order a code with an automatic drain or the default differential-pressure drain instead - all three options exist across the GFR range in this size.
