The AirTAC GFR30015ALJC2K AirTAC Filter Regulator PT1/2 Low-Pressure 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 automatic 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 GFR30015ALJC2K is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration carries a PT1/2 port, an automatic drain that expels collected condensate without manual attention, and a 40 um standard filter element. The regulator is the low-pressure (L) type, an external round gauge scaled in psi is fitted, and a reverse (check) valve is included; the J code means no mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the bowl is polycarbonate.
This is a genuine AirTAC part. The GFR300 series is also available in other port sizes and thread options (PT as standard, with G and NPT to order), manual or differential-pressure drains, a 5 um filter element (code W), embedded square gauges with MPa, psi or bar scales, and with or without a bracket. AirTAC publishes flow as curves rather than a single rated figure, so ask us to confirm flow and 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.

| 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. |

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.

Point-of-use conditioning ahead of air cylinders on a clamping or workholding fixture: the filter removes water and particulate, the low-pressure regulator holds a steady setting, and the round psi gauge gives the operator a local readout.
Supplying clean, regulated air to spray guns on a paint or coating line, where the 40 um element keeps moisture and debris out of the finish and the automatic drain clears condensate during continuous booth operation.
Conditioning air for diverters, sealers and gripper cylinders along a packaging conveyor, with the check valve holding the circuit and the automatic drain keeping condensate away from downstream valves.
The real choices within GFR300: step up or down in size (200/300/400/600) and port to match the flow your line needs - the larger the size, the larger the port and flow capacity. Choose the drain: this unit has an automatic drain, with manual and differential-pressure drains as the catalogue alternatives. Filter grade is 40 um standard here; specify W for the 5 um element where finer filtration is required. For the gauge, this unit carries an external round gauge scaled in psi, while embedded square gauges with MPa, psi or bar scales are the other option. Thread is PT as standard, with G (BSPP) and NPT as order options, and the J code means no mounting bracket is fitted. The L code makes this the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us. Because AirTAC publishes flow only as curves, not a single rating, ask us to confirm sizing 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 one number. Send us your application details and we will confirm the flow and datasheet figures for GFR30015ALJC2K on request.
The A code fits an automatic drain that expels collected condensate from the polycarbonate bowl without manual attention. Manual and differential-pressure drains are catalogue alternatives - tell us which you prefer when ordering.
