The AirTAC GC400C10ALC2WK AirTAC F.R.L. Combination, PT3/8 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This GC400C10ALC2WK is the size 400 unit with a PT3/8 (3/8 in) port. The filter carries the 5 um element (code W) for finer water and particulate removal, with an automatic drain (code A) that expels collected condensate without manual attention. The regulator is the low-pressure type (code L), and the set is fitted with a round gauge scaled in psi (code C2), a reverse/check valve (code K) and a mounting bracket. The filter bowl on this size is polycarbonate. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature 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 port sizes from 1/8 in to 1 in, and options including G or NPT threads, manual or differential-pressure drains, the standard 40 um element, gauge scales in MPa, psi or bar, and embedded square or external round gauges. Flow is published as curves rather than a single rated figure, so ask us to 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

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-C1 filter, GR400-C1 regulator and GL400-C1 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 impact wrenches and nutrunners on a low-pressure tool circuit: the 5 um element keeps fine contamination out of the tools, the lubricator delivers a continuous oil mist, and the round psi gauge lets line technicians read the setting at a glance.
Supplying carton sealers and case-packer cylinders on a packaging conveyor: filtered, regulated and lubricated air from one set, with the reverse/check valve fitted to guard the downstream circuit and the automatic drain clearing condensate through shift-long running.
Providing conditioned air to gauges, fixtures and test instruments on a bench rig: the low-pressure regulator suits sensitive circuits, the 5 um grade protects fine components, and the psi-scaled round gauge gives a direct reading during test set-up.
Choose the size and port step (200/300/400/600, 1/8 in to 1 in) against the flow your line needs - the larger the size, the larger the port and flow capacity. On this configuration the choices are already fixed: 5 um filtration instead of the standard 40 um, an automatic drain instead of manual or differential-pressure, a low-pressure regulator, a round gauge scaled in psi, a reverse/check valve and a mounting bracket. The same series can be ordered with different options if your application calls for them. Thread is PT as standard; G (BSPP) and NPT are order options. 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 GR400-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and sizing figures from the datasheet on request.
The L code marks the low-pressure regulator variant of this set. Its exact adjustment range is not published in the standard table, so ask us to confirm the range for your setting before ordering. Note this configuration also carries the 5 um filter element (code W) instead of the standard 40 um.
