The AirTAC GC40010LC2WK AirTAC F.R.L. Combination, PT3/8, 5 um 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 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40010LC2WK is a genuine AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-treatment set for compressed air. This size 400 unit is fitted with a PT3/8 (3/8 in) port, and the filter element is the fine 5 um grade (code W), so it removes water and particulate down to 5 um before the air reaches the regulator and lubricator. The drain is differential-pressure type, the regulator is the low-pressure (L) type, and this configuration carries a round external gauge with a psi scale plus a reverse/check valve (code K); the mounting bracket is included.
This is a genuine AirTAC part from the GC range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, thread options PT (standard), G and NPT, drain choices, 40 um or 5 um filtration, and gauge or no-gauge variants. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow 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.

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 robotic assembly cell where actuators and grippers need filtered, regulated and lubricated air from one treatment point, with the fine 5 um element protecting downstream valves from fine particulate.
Supplies spinning and weaving machines that rely on a continuous oil-mist carry-over to keep pneumatic cylinders and bearings running, with regulation handled by the low-pressure type regulator.
Conditions air for a clamping or holding circuit that runs at reduced pressure, where the low-pressure regulator type, psi-scale round gauge and reverse/check valve hold the setting and guard against backflow.
Size 400 with a PT3/8 port sits in the middle of the GC range: step down to 200/300 for smaller lines or up to 600 where larger porting is needed, matched against the flow your line requires. This unit is already specified with the fine 5 um filter grade (the 40 um standard grade is the alternative), differential-pressure drain, low-pressure regulator type, round psi-scale gauge and a reverse/check valve, with the bracket included. Thread is PT as standard; G (BSPP) and NPT are order options if your pipework needs them. Because flow for this series 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 GR400-10 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 we do not quote one number. Tell us your line pressure and air demand and we will confirm the flow and datasheet figures for this exact configuration on request.
The L code marks the low-pressure regulator variant of the GC series, intended for circuits set below the standard range. The exact adjustment range for this variant is not published in our sheet, so we confirm it against the datasheet on request. The unit also carries a round psi-scale gauge and a reverse/check valve (code K).
