The AirTAC GC30008ALC2GK AirTAC F.R.L. Combination, G1/4 Port 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 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30008ALC2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This 300-size configuration carries a G1/4 (BSPP) port, an automatic drain on the filter bowl so collected condensate is expelled without manual attention, a 40 um standard filter element, a low-pressure type regulator, and a round pressure gauge reading in psi. A reverse/check valve is fitted, and the set includes a mounting bracket.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with a choice of ports, drain types, 40 um or 5 um (W) filtration, gauge style and scale, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so we confirm the datasheet and sizing figures 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.
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Feeds clean, regulated and lubricated air to pneumatic nutrunners and clamps along a vehicle assembly line, with the automatic drain handling condensate during continuous shifts.
Supplies filtered, pressure-controlled and oil-misted air to the clamping cylinders and tool-change actuators on a machining centre, with the psi gauge giving operators a local reading.
Prepares air for the diverters, pushers and stop gates on a carton packaging conveyor, keeping cylinders lubricated and the supply free of water and particulate.
Start with the size and port: 300 is the mid step of the four GC sizes (200/300/400/600), and this unit takes a 1/4 in port in G (BSPP) thread; PT is the catalogue standard and NPT can be ordered. Choose the drain type for the filter bowl - differential-pressure (default), automatic (as fitted here) or manual - and the filter grade: 40 um standard or 5 um with code W. For the regulator, decide between the standard and low-pressure (L) type; this unit is the low-pressure type, and its exact regulation range is not published, so ask us to confirm it. Gauge options are the embedded square gauge or an external round gauge with MPa, psi or bar scales - this configuration has a round psi gauge. A reverse/check valve (K) and bracket are fitted here.
Because flow is published only as curves and not as a single rated figure, send us your application details 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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated figure, so there is no one rated flow number we can quote. Send us your application details and we will confirm the flow and sizing figures from the datasheet on request.
The L in the code marks the low-pressure version of the regulator, intended for supplies that sit below the standard regulator's working band. The exact regulation range for this low-pressure type is not published in our sheet, so please ask us to confirm it against the datasheet before ordering.
