The AirTAC GC30010C2GK AirTAC F.R.L. 3/8 in G-Thread 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 PT3/8" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30010C2GK 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 for compressed air. This configuration is size 300 with a 3/8 in port in G (BSPP) thread, fitted with a round psi-scale pressure gauge, a reverse/check valve, and the included mounting bracket. The filter element is the standard 40 um grade, the bowls are polycarbonate, and the bowls use differential-pressure drainage, which bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough - no daily manual draining on a well-sized installation.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of PT, G or NPT thread, automatic, manual or differential-pressure drains, a 5 um filter element option (code W), gauge scale in MPa, psi or bar, and an optional reverse/check valve. Flow is published in the AirTAC catalogue as curves rather than a single rated figure, so ask us to confirm the flow and 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. 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: GF300-10 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.

Feeding air cylinders on a bench or gantry assembly press: the filter strips water and 40 um particulate, the regulator holds a steady working pressure for repeatable cylinder stroke, and the lubricator mists oil to the valve and cylinder seals.
Supplying the air cylinders, grippers and stop-gates on a packaging or conveyor line, where clean, regulated and lubricated air keeps directional valves cycling reliably through long production shifts.
A point-of-use F.R.L. at the air drop feeding a CNC machine, air chuck or clamping fixture, giving the operator a local psi gauge, a set working pressure and a reverse/check valve to hold the circuit if supply pressure dips.
Start with the size and port: GC300 carries a 3/8 in port, one step up from GC200 (1/4 in) and one step down from GC400 (1/2 in), so match the step to the air consumption of the machine it feeds. Drain type is a real choice on this family: differential-pressure (this unit's default), fully automatic, or manual. Filter grade is 40 um standard or 5 um with code W - choose 5 um only where downstream equipment needs finer filtration. Gauge scale is selectable: this unit carries the round gauge in psi; square embedded gauges and MPa or bar scales are also available. Thread is G (BSPP) here, with PT and NPT as orderable options, and the mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the correct size and flow data from 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not state a flow number here. Tell us your working pressure and the air consumption of the equipment you are feeding, and we will confirm the correct size and the flow data from the datasheet before you order.
C indicates the round external pressure gauge and 2 sets its scale to psi (MPa and bar scales are also available). K means a reverse/check valve is fitted, which holds downstream pressure if the upstream supply drops. The unit also carries the standard 40 um filter element, differential-pressure drains, and a G (BSPP) 3/8 in port; PT and NPT threads and a 5 um element are orderable options.
