The AirTAC GC40015LC2GK 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 GC40015LC2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This 400-size unit is built for 1/2 in (G1/2) ports and carries a 40 um filter element with a differential-pressure drain, a low-pressure type regulator, a round pressure gauge reading in psi, and a reverse (check) valve fitted downstream of the regulator. A mounting bracket is included, and the polycarbonate bowls suit compressed-air service from -5 to 70 C (non-freezing) at inlet pressures up to 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, a choice of 40 um or 5 um (W) filtration, differential-pressure, automatic or manual drains, square (embedded) or round external gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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: GF400-15 filter, GR400-15 regulator and GL400-15 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.

Feeding 1/2 in branch lines that serve impact wrenches and pneumatic clamps on a vehicle assembly line, where filtered, regulated and lubricated air keeps tools running shift after shift.
Supplying the air cylinders on a carton-forming and sealing conveyor, where the lubricator mists oil to the actuators and the check valve holds downstream pressure if the supply drops.
Preparing air for a bench-mounted pneumatic press or clamping fixture, where the low-pressure type regulator holds a gentle setpoint and the psi gauge lets the operator verify it at a glance.
Start with the port and size step: this unit is the 400 size with a 1/2 in G-thread port; smaller or larger sizes (200/300/600) move the port and flow capacity up or down, so match the step to your line's air demand. The 40 um element is the standard grade; choose the 5 um (W) option where downstream equipment needs finer particulate removal. Drain is differential-pressure here, which bleeds collected condensate as the pressure differential rises; automatic (A) or manual (M) drains are available if your maintenance routine suits them better. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are alternatives. The L code makes this a low-pressure type regulator - confirm the exact adjustment range with us before ordering if your setpoint is critical. Thread is G here; PT is the catalogue standard and NPT is also orderable. A bracket is included, and the K code means a reverse/check valve is fitted to hold downstream pressure. Because flow is published as curves and not a single rating, send us your application details and we will confirm sizing against the datasheet before you order.
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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the air demand of your equipment, and we will confirm the flow and sizing against the datasheet on request before you order.
L marks the low-pressure type regulator, and K means a reverse (check) valve is fitted so downstream pressure is held if the upstream supply fails. The exact adjustment range for the low-pressure type is not published in our sheet, so confirm it with us on request if your setpoint matters.
