The AirTAC AirTAC GC30008ALC2WGK F.R.L. Unit G1/4 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 PT1/4" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30008ALC2WGK is a three-piece F.R.L. combination that conditions compressed air in one assembly: a filter to remove water and particulate, a regulator to set downstream pressure, and a lubricator to add oil mist for downstream air tools and cylinders. This size 300 unit is configured with a G1/4 port (PT is the standard thread form; G and NPT are order options), a fine 5 um filter element (code W, versus the 40 um standard), an automatic drain on the filter bowl, the low-pressure regulator type, a round external gauge scaled in psi, a reverse/check valve, and a mounting bracket. 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 available in sizes 200, 300, 400 and 600 with matching port sizes, and with choices of filter grade, drain type, gauge style and scale, thread form and reverse valve. Flow is published by AirTAC as curves rather than a single rated figure, 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.

|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic 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. |

| 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: GF300-08 filter, GR300-08 regulator and GL300-08 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 filtered, regulated and lubricated air to the clamping fixtures and air-powered tooling on a CNC machining centre, with the 5 um element protecting fine valves and the low-pressure regulator suiting low-pressure actuation circuits.
Conditioning the air supply for pneumatic cylinders, diverters and grippers on a packaging or bottling conveyor, where the automatic drain keeps condensate out of the circuit during continuous shifts and the lubricator mist extends cylinder seal life.
Installed as a point-of-use F.R.L. on a drop line at an automotive assembly station, supplying regulated, lubricated air to impact drivers and air ratchets, with the round psi gauge letting operators verify set pressure at a glance.
Sizing a GC combination starts with the port and size step: 200, 300, 400 and 600 step up in port and flow capacity, so pick the size that matches your line's air demand - here the 300 size with G1/4 ports. Choose the filter grade: 40 um is the standard element and 5 um (this unit, code W) suits finer protection of valves and cylinders. Choose the drain: differential-pressure (default), automatic (this unit, which empties the bowl without manual attention) or manual. On the regulator, decide standard versus low-pressure type - this unit is the low-pressure type - and pick the gauge: embedded square gauge standard, external round gauge optional, with MPa, psi or bar scales. This unit carries the round gauge in psi. Select the thread: PT is the standard, with G (BSPP) and NPT as order options, and decide whether a reverse/check valve (fitted here) and bracket (included here) are needed. Because flow is published as curves rather than a single rating, 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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and required flow, and we will confirm the sizing from the datasheet on request before you order.
The W in the code GC30008ALC2WGK selects the optional 5 um element instead of the 40 um standard, giving finer protection for downstream valves and cylinders. The A selects the automatic drain, which expels collected condensate from the filter bowl without manual intervention - useful on lines that run unattended.
