The AirTAC GFR30015ALJC2WG 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 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 AirTAC GFR30015ALJC2WG is a size-300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration carries a G1/2 (BSPP) port, a 5 um filter element (the finer of the two published grades), an automatic drain that ejects collected condensate without manual attention, and the low-pressure regulator type. An external round gauge scaled in psi is fitted so the downstream setting can be read directly, and no mounting bracket is included. The polycarbonate bowl suits the non-freezing -5 to 70 C operating window, with a maximum inlet pressure of 1.0 MPa (145 psi).
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, and PT, G or NPT threads. Because flow is published as curves rather than a single rating, we confirm the datasheet figures for your application on request.

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". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 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. |
| G | G (BSPP) 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.

Conditions and regulates the air feeding clamp cylinders on a fixture, with the 5 um element protecting valve spools and the round psi gauge letting a setter verify clamp pressure at the panel.
Mounted at the drop of a carton-sealing or wrapping line, it removes water and debris from the mill air and holds a steady low-pressure setting for the machine's actuator circuit, draining condensate automatically between shifts.
Prepares the supply to benchtop pick-and-place and dispensing modules, filtering to 5 um ahead of sensitive pilot valves while the low-pressure regulator type suits circuits running well below standard line pressure.
Step up or down through the GFR sizes (200/300/400/600) against the port and flow your line needs; this unit sits at size 300 with a 1/2 in port. Choose the drain to match attendance: automatic (this unit) for unattended duty, manual for periodic checks, or the differential-pressure default. Pick 5 um (this unit) where downstream valves and cylinders need finer air than the 40 um standard. Gauge style and scale (round psi here, or embedded square with MPa/psi/bar), thread (PT is the standard; G and NPT are order options), and bracket inclusion are all decodable choices. Note this is the low-pressure regulator type; its exact adjustment range is not published, so tell us your setpoint and we will confirm suitability. Flow is published 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Send us your required port size and consumption and we will confirm the flow figures from the datasheet for this exact model on request.
The A in the code specifies an automatic drain, which ejects collected condensate from the bowl without anyone opening it - useful on lines that run unattended. The same GFR300 size is also available with a manual drain or the differential-pressure default, and with the 40 um standard element instead of this 5 um one.
