The AirTAC GC300C10LC2GK AirTAC 3/8" F.R.L. Combination Unit 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator that together remove water and particulate, regulate pressure and add oil-mist lubrication on one compressed-air line. This GC300C10LC2GK is the size 300 unit for a G3/8 port. The filter carries the standard 40 um element with a differential-pressure drain in a polycarbonate bowl, the regulator is the low-pressure type fitted with an external round gauge scaled in psi, and a reverse/check valve is fitted. A mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600 with ports from 1/8" to 1", and options include automatic or manual drains, a 5 um element (code W), embedded square or external round gauges scaled in MPa, psi or bar, and G or NPT threads alongside the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm flow and other 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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-C1 filter, GR300-C1 regulator and GL300-C1 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 cleaned, regulated and lubricated air to the cylinders and grippers on a carton erector and sealer in a food or consumer-goods plant, where the 40 um element and oil mist keep valves and actuators working over long shifts.
Supplying impact wrenches, nutrunners and air ratchets at a final-line assembly cell, with the low-pressure regulator set to the tool's working pressure and the lubricator misting the tool motors.
Running clamping fixtures, tool-change cylinders and chip conveyors on a machining centre, where the reverse/check valve holds the downstream circuit and the drain keeps condensate out of the valve stack.
Pick the size step (200/300/400/600) and its port against the air demand of your line; this unit is size 300 with a G3/8 port. Drain choice matters: the differential-pressure drain fitted here bleeds with airflow, automatic (code A) drains on condensate level, and manual (code M) needs periodic draining. The standard element is 40 um; specify W for the 5 um grade where finer filtration is required. Gauges are the embedded square type as standard with an external round gauge optional, scaled in MPa, psi or bar - this unit carries a round psi gauge. Threads are PT as standard with G and NPT as orderable options, and a bracket is included here. Flow is published as curves rather than a single rating, so 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-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a number here. Tell us your line demand and we will confirm the correct size and flow from the datasheet on request.
The L in the code marks the low-pressure regulator type; its exact adjustment range is not published in the catalogue, so we confirm it on request. C2 means an external round gauge scaled in psi is fitted, while the embedded square gauge with MPa, psi or bar scales is the standard alternative.
