The AirTAC GFR30015LJC2W AirTAC Filter Regulator PT1/2 Low-Pressure 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 differential-pressure 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 GFR30015LJC2W is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air through a fine 5 um element (the W grade, finer than the standard 40 um) and regulates downstream pressure in a low-pressure configuration. This unit is built with a 1/2 inch PT threaded port, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a round pressure gauge reading in psi. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and is ordered with choices of drain type, filter grade, gauge style and scale, thread (PT standard, G or NPT to order) and bracket. Flow is published by AirTAC as curves rather than a single rated figure, so 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.

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.

A filter regulator feeding clamp cylinders on a CNC fixture: the 5 um element keeps sludge and scale out of the clamp valves while the low-pressure regulator holds the lighter holding pressure the fixture design calls for.
On a cartoning or wrapping line, this unit conditions and regulates the air feeding small actuator circuits that run at reduced pressure, with the psi gauge giving operators a direct reading at the machine.
Supplying filtered, regulated air to panel-mounted indicators and pneumatic sensors in a process area, where the fine 5 um grade protects sensitive orifices and the differential-pressure drain keeps moisture moving out without manual attention.
Start with the port step: this unit is size 300 with a 1/2 inch PT port, one step up from the 3/8 inch size-300 alternative and below the 3/4 inch size-400. Match the port to the air line and let the required flow guide the size - and because AirTAC publishes flow as curves rather than one rating, ask us to confirm sizing against your application before ordering. This code carries the 5 um W-grade element; the standard 40 um grade suits coarser protection, while 5 um suits downstream valves, cylinders and instruments that need cleaner air. Drain is the differential-pressure type here; automatic (A) and manual (M) drains are available if your duty cycle or maintenance routine calls for them. The gauge in this code is the round external type reading in psi; an embedded square gauge with MPa, psi or bar scales is the alternative. Thread is PT as standard, with G (BSPP) and NPT as order options, and this code omits the mounting bracket (J).
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 GFR flow as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your line pressure, downstream demand and allowable pressure drop, and we will confirm the sizing from the datasheet on request before you order.
L marks the low-pressure regulator type, for applications regulated below the standard range - the exact range is not published in the catalogue, so we confirm it on request. C2 specifies the round external gauge with a psi scale, and W specifies the fine 5 um filter element instead of the standard 40 um grade.
