The AirTAC GC300C10C2GK AirTAC F.R.L. Combination Unit, G3/8 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator built up as one unit, so incoming compressed air is cleaned of water and particulate, regulated to your set pressure, and given an oil mist for downstream air tools. This GC300C10C2GK is the 300 size with a G3/8 port. It carries the standard 40 um filter element with a differential-pressure drain on the filter bowl, a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi), a round psi gauge, and a reverse (check) valve fitted. 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 is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options including 5 um filtration (code W), automatic or manual drains, gauge scale in MPa, psi or bar, and G or NPT threads as order options (PT is the standard thread). Flow is published as curves rather than a single rated figure, so ask us to confirm the 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 impact wrenches, ratchets and air screwdrivers at assembly stations: the filter removes water and swarf from the shop air, the regulator holds a steady set pressure at the tool, and the lubricator carries an oil mist to keep the tool motors running.
Supplying the pneumatic cylinders and stopper gates on a packaging conveyor: clean, regulated air protects the cylinder seals, and the check valve holds the downstream circuit stable when the main supply dips during shift changeovers.
Air preparation for pneumatic clamps and workholding fixtures on a CNC cell: the 40 um element keeps grit out of the clamping valves, the regulator sets a repeatable clamping pressure, and the lubricated air conditions the actuator side of the circuit.
The real choices in this series are the size and port step (200/300/400/600, 1/8 to 1 inch) matched to the flow your line needs; the drain type on the filter bowl (differential-pressure as here, automatic, or manual); the filter grade (40 um standard, 5 um with code W); the gauge and its scale (an embedded square gauge is standard, an external round gauge is optional, in MPa, psi or bar); the thread (PT standard, G or NPT to order); and the reverse/check valve (code K, fitted on this unit). Flow for each size is published as curves, not a single rating, so send us your flow and pressure requirements 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 GR300-C1 regulator with a GF300-C1 filter on that branch.
Flow for this series is published as curves in the AirTAC datasheet rather than as a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm from the datasheet whether the 300 size at G3/8 is correctly sized for your application before you order.
The filter bowl on this GC300 is fitted with a differential-pressure drain as the standard arrangement: it uses the pressure drop across the filter element to expel collected condensate while the unit is working, so there is no drain code in the model. Automatic (code A) and manual (code M) drains are available as order options if your installation prefers them.
