The AirTAC GC40015ALC2WG AirTAC F.R.L. Combo, G1/2, 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 PT1/2" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one coordinated set. This GC40015ALC2WG is the 400 size with a G1/2 (BSPP) port. The filter element is the fine 5 um grade (code W) and the bowl drains itself via the automatic drain, so collected water leaves the bowl without anyone opening it. The regulator is the low-pressure type, and the set is ordered with the external round gauge on a psi scale. The bowls are polycarbonate (PC), and the mounting bracket is included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600, with a choice of drain type (differential-pressure, automatic or manual), 40 um standard or 5 um fine filtration, gauge scale in MPa, psi or bar, and PT (standard), G or NPT threads. Flow is published 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.

|---|---|
| 15 | Port size PT1/2". 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. |
| 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. |
| (blank) | No reverse-flow valve (the default). |
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: GF400-15 filter, GR400-15 regulator and GL400-15 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 pneumatic clamps and tool-change cylinders on a machining centre, with the 5 um element protecting fine valves from particulate and water carryover.
Conditions the air feeding conveyor stoppers, pushers and sealing cylinders on a packaging line, where the automatic drain handles condensate during continuous shifts and the lubricator keeps actuator seals working.
Supplies conditioned air to pneumatic nutrunners and clamping fixtures at an assembly station, with the low-pressure regulator holding a gentle setpoint and the psi gauge letting operators check line pressure at a glance.
Start with the port and size: the 400 size with a 1/2 in connection suits lines running larger pneumatic loads, while 200/300 cover smaller circuits and 600 the largest. Because flow is published as curves rather than a single rating, send us your air demand and we will confirm the right size against the datasheet before you order. On this set the working choices are already made: 5 um fine filtration instead of the 40 um standard element, an automatic drain instead of manual or differential-pressure, a low-pressure regulator instead of the standard type, and a round psi gauge instead of the embedded square gauge. If your circuit needs different choices, the same size is available with 40 um filtration, another drain type, a standard regulator, or a square gauge in MPa, psi or bar. Thread options are PT (standard), G or NPT; this unit is ordered with the G thread. Note that the low-pressure regulator's exact adjustment range is not published in the catalogue - confirm it with us for your setpoint.
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 GR400-15 regulator with a GF400-15 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 figure that is not in the datasheet. Send us your operating pressure and air demand and we will confirm the flow and correct sizing against the datasheet on request before you order.
The L in the code marks the low-pressure regulator variant rather than the standard one, intended for circuits that run at lower setpoints. Its exact adjustment range is not published in the catalogue, so confirm your target setpoint with us and we will verify suitability on request. The rest of the decode is standard: 5 um filtration, automatic drain, round psi gauge and G1/2 thread.
