The AirTAC GC30010LC2WGK AirTAC F.R.L. Combination, G3/8, 5 um 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 5 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, a pressure regulator and a lubricator assembled as one air-treatment set, so the same air stream is filtered, regulated and lubricated in a single installation. This GC300 configuration is the 300 size with a G3/8 port (PT is the standard thread; G and NPT are catalogue options). It carries the W filter element (5 um, finer than the standard 40 um), a differential-pressure drain on the filter bowl, the low-pressure type regulator, a round gauge reading in psi, a reverse/check valve, and the mounting bracket is included. The filter and lubricator bowls on this size are PC (polycarbonate).
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with matching port sizes, and with options such as drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um with W), gauge style and scale, thread form and reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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 changers and air-powered actuators on a CNC machining centre, with the 5 um element protecting fine valve internals from particulate carry-over.
Supplies the pick-and-place cylinders and diverters on a carton packaging line: the filter removes water and dirt, the low-pressure regulator holds the setting the cylinders were designed around, and the lubricator mists oil to the moving seals.
Mounted at the drop leg of an assembly bench, it treats the air feeding air screwdrivers, riveters and clamping fixtures, with the reverse/check valve holding the downstream setting if the main supply dips.
Start with the size and port: this unit is size 300 with a G3/8 port; step up or down through sizes 200/300/400/600 as your line's flow demand and piping require, and match the thread to your installation (PT standard, G or NPT to order). Filter grade is a real choice: 40 um is the standard element, while this unit's W code selects the finer 5 um element for cleaner air downstream. Drain type is also selectable: differential-pressure (fitted here), automatic, or manual. For the regulator, this is the low-pressure type; the exact adjustment range for this variant is not published, so confirm it with us before ordering. Gauge style and scale are selectable (embedded square gauge standard, external round gauge optional, scales in MPa, psi or bar); this unit has a round gauge reading psi. A reverse/check valve is fitted (code K) and the mounting bracket is included. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application 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 curves, not as a single rated number, so we do not quote a flow figure for this unit. Tell us your application and line conditions and we will confirm the sizing from the datasheet on request before you order.
W selects the 5 um filter element instead of the standard 40 um element, for finer particulate removal. This unit's drain is the differential-pressure type (the default): it discharges collected condensate when the pressure differential across the bowl rises. Automatic (A) and manual (M) drains are available as ordering options on the GC family.
