The AirTAC GFR30015LC2WG AirTAC Filter Regulator G1/2 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 GFR30015LC2WG is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the 300 size with a G1/2 (BSPP) female port, a 5 um filter element (code W, against the 40 um standard), a differential-pressure drain on the bowl, and the low-pressure regulator type. A round pressure gauge reading in psi is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, offered with manual, automatic or differential-pressure drains, 40 um or 5 um filtration, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). 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.

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 low-pressure air to the pneumatic cylinders on a carton-forming and sealing machine, with the 5 um element protecting the directional valves downstream.
Supplying regulated air to pneumatic clamps on a CNC machining fixture, where the low-pressure regulator type holds a reduced clamping pressure and the bowl drains itself via differential pressure.
Regulating air to diverter and stopper cylinders on a bottling-line conveyor, with the psi round gauge letting operators check the set pressure at a glance.
Size and port set the flow path: the 300 size with a G1/2 port suits lines plumbed at 1/2 inch; step up to the 400 or 600 size where demand is higher. The 5 um element (code W) is the choice where finer particulate removal matters, while the 40 um standard element suits general downstream protection. The differential-pressure drain (the default) clears bowl condensate without manual attention; automatic (A) and manual (M) drains are order options. The round gauge on this unit reads in psi, with MPa and bar scales available. The L in the code marks the low-pressure regulator type, intended where controlled pressures sit below the standard range - ask us to confirm its exact adjustment span from the datasheet.
Thread here is G (BSPP); PT is the standard thread and NPT is also an order option, so match the thread to your piping before ordering. A mounting bracket is included. Because flow is published as curves rather than one rated figure, send us your flow and pressure requirements 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 GFR300 flow as curves rather than a single rated figure, so there is no one number we can quote. Send us your required flow and working pressures and we will confirm against the datasheet whether the 300 size and its G1/2 port suit your line.
L marks the low-pressure regulator type, intended for applications where the controlled downstream pressure sits below the standard regulator range. The exact adjustment span for the low-pressure type is not listed in the summary data, so ask us to confirm it from the datasheet before ordering.
