The AirTAC GC40010ALC2GK AirTAC F.R.L. Combination, 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 PT3/8" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40010ALC2GK is an AirTAC GC series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one conditioning set. This size 400 unit is configured with a G3/8 (3/8 in) port, automatic drain on the filter bowl, the standard 40 um filter element, a low-pressure regulator type, a round pressure gauge reading in psi, a reverse/check valve, and a mounting bracket. The filter removes water and particulate before regulation, the regulator holds a stable downstream pressure, and the lubricator adds oil mist for downstream air tools and cylinders. Bowls on the 400 size are polycarbonate (PC).
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a choice of ports and thread types (PT standard; G and NPT as order options), drain types (differential-pressure, automatic or manual), 40 um or 5 um (W) filtration, gauge style and scale, and reverse/check valve. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details against 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 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. |

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: GF400-10 filter, GR400-10 regulator and GL400-10 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 a stamping or assembly press where cylinders and clamps need filtered, regulated and lubricated air at a stable low-pressure setting, with the psi gauge letting operators verify the set point at a glance.
Conditions the air supply for diverters, sealers and pick-and-place actuators along a packaging line, with automatic drain keeping condensate out of the bowls without daily manual attention.
Serves a workbench or cell drop feeding impact wrenches, grinders and air motors, where the lubricator's oil mist extends tool life and the reverse/check valve holds the circuit if supply pressure is lost.
Size and port drive the choice: the GC400 with its G3/8 port sits in the middle of the 200/300/400/600 range, so step up or down depending on the air demand of the machines downstream - larger sizes carry larger ports and more flow. The drain is decodable: this unit has an automatic drain (code A), while differential-pressure (blank) and manual (M) are the other catalogue options. Filtration is the standard 40 um element; specify W for the 5 um grade where finer particle capture is needed. The gauge here is the external round type with a psi scale; embedded square gauges and MPa/bar scales are the alternative options. Thread is G (BSPP) on this unit - PT is the standard, with G and NPT as order options - and the bracket is included on this configuration. Flow for the series is published as curves, not a single rating, so 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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for the GC 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 sizing from the datasheet flow curves on request before you order.
The L in the code marks the low-pressure regulator type, suited to circuits that run at reduced downstream settings; the exact adjustment range for this type is not published, so confirm it with us. The A sets an automatic drain, which expels collected condensate from the filter bowl on its own - the alternatives are manual drain (M) and the differential-pressure default (blank).
