The AirTAC GC30010LC2GK AirTAC F.R.L. Combination G3/8 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 PT3/8" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30010LC2GK is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one GC300 unit. It cleans compressed air of water and particulate down to 40 um, regulates downstream pressure with the low-pressure type regulator, and adds oil mist for downstream air tools and cylinders. This configuration has G3/8 (3/8 in) ports with G thread, a differential-pressure drain on the filter bowl, a round gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included. The filter and lubricator bowls are polycarbonate, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, drain types (differential-pressure, automatic, manual), a 5 um filter option (code W), gauge scale choices, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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: GF300-10 filter, GR300-10 regulator and GL300-10 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.

Feeds filtered, regulated and lubricated air to the clamps, tool-change actuators and air jets on a CNC machining centre, with the psi gauge giving operators a visible setpoint at the machine.
Supplies treated air to the cylinders and grippers on a carton-forming and sealing conveyor, where the lubricator keeps seals moving smoothly through long production shifts.
Conditions the air feeding paint spray guns in a finishing booth: the 40 um filter removes water and debris that would spoil finish quality, while the low-pressure regulator suits the modest supply pressures spray work needs.
Size up the GC series by port and expected flow: this GC300 unit carries 3/8 in ports, and the larger 400 and 600 sizes move more air - match the step to your consumption. The blank drain code on this model is the differential-pressure type; automatic (A) and manual (M) drains are available if your maintenance routine suits them better. The standard 40 um filter grade suits general plant air; specify the W option for 5 um filtration where finer protection is needed. The fitted round gauge reads in psi; square gauges and MPa or bar scales are alternatives. Thread: PT is the AirTAC standard, with G and NPT as order options - this unit is built with G thread. A bracket is included on this configuration. Because flow is published as curves rather than a single rated figure, 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated figure, so no single flow number is stated here. We can confirm the datasheet and check the curve against your application's air consumption before you order - just ask.
The L marks the low-pressure type regulator; the exact adjustment range for this type is not published, so confirm it with us if your setpoint is critical. The blank drain code means the filter uses a differential-pressure drain, with automatic (A) and manual (M) drains available as alternatives in the GC series.
