The AirTAC GFR30015MLJF2W 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 GFR30015MLJF2W is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body, with a 1/2 in PT port. It removes water and particulate down to 5 um via the W-grade element and holds a set downstream pressure on low-pressure circuits. This configuration has a manual drain bowl in polycarbonate, a fitted embedded square gauge scaled in psi, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, gauge and thread options, and a low-pressure type where the circuit calls for it. Flow is published as curves rather than a single rating, so ask us to confirm 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". |
| 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. |
| (blank) | PT 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.

Feeding filtered, regulated air to the directional valve and cylinder circuit of a low-pressure pneumatic press or clinching station, where the 1/2 in port matches the main air drop and the 5 um element protects the valve spools.
Conditioning the air supply to grippers, pushers and diverters on a cartoning or case-packing conveyor line, holding a steady regulated pressure so pick-and-place motions stay repeatable through the shift.
Serving as the point-of-use filter regulator at an assembly-cell air drop, removing water and fine particulate before the cell's fittings and actuators, with the psi gauge giving operators a local pressure readout.
Size 300 with a PT1/2 port suits lines where 1/2 in piping is already run; step up or down a size if your flow demand changes, since larger sizes carry larger ports. The 5 um W-grade element is the right pick when downstream valves or instruments are sensitive to finer particles; the 40 um standard element covers general-duty circuits. Manual drain means an operator opens the bowl drain during checks - choose automatic or differential-pressure drain if the unit sits where regular manual draining is impractical. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. PT is the standard thread, with G (BSPP) and NPT available as order options, and a bracket can be added if this J (no bracket) version needs panel fixing. Flow is published as curves, not a single rating, so send us your application details 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, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the relevant flow and datasheet figures for this exact model on request.
The M in the code specifies a manual drain bowl: condensate is released by opening the drain during routine checks. If the unit will be mounted where regular manual draining is awkward, the GFR300 is also available with automatic or differential-pressure drains - ask us for the alternative model code.
