The AirTAC GC30015LF2GK AirTAC F.R.L. Combination G1/2 Low-Pressure is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT1/2" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015LF2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one conditioning set for compressed air. This 300-size unit is built with G1/2 ports, a 40 um filter element, a differential-pressure drain on the filter bowl, and a low-pressure-type regulator. The square pressure gauge fitted to the regulator reads in psi, a reverse/check valve is fitted, and the set includes a mounting bracket. The polycarbonate bowls suit the -5 to 70 C (non-freezing) operating range, with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port options, thread choices (PT standard; G and NPT as order options), drain types, 5 um filtration (code W), gauge scales in MPa, psi or bar, and bracket options. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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. The combination has no separate bracket code — the three units couple together with their own mounting hardware. 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, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF300-15 filter, GR300-15 regulator and GL300-15 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

A workholding or light-forming press fed by shop air gets filtered, regulated and lubricated supply in one GC set, with the check valve holding the downstream circuit if upstream pressure dips.
Case packers, sealers and labelling heads on a packaging line run on cylinders and air motors; this combination conditions the branch line at the machine, with oil mist carry-over for actuator life.
A CNC cell's air drop for clamping, chip blow-off and spindle-seal air takes one GC300 set at the machine entry: 40 um filtration, regulated low-pressure supply and lubrication where needed.
Choose the GC size by the port and flow step you need: this 300-size unit carries G1/2 ports, and larger sizes step up in port and flow capacity. The filter element is 40 um as standard; specify code W for 5 um if downstream equipment needs finer filtration. Drain choice is differential-pressure (as fitted here), automatic (code A) or manual (code M). The regulator here is the low-pressure type (code L); its adjustment range is not published in the standard tables, so confirm it with us against your set pressure. Gauge scale is psi on this unit, with MPa or bar available, and an external round gauge is an option. Thread is G (BSPP) on this code; PT is the standard and NPT is an order option. A bracket is included. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as 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 this 300-size, G1/2 unit before you order.
L marks the low-pressure-type regulator, whose adjustment range is not published in the standard tables - confirm it with us against your set pressure. K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply drops. This unit also carries a square gauge reading in psi and a differential-pressure drain on the filter bowl.
