The AirTAC GC40010LC2WGK AirTAC F.R.L. 3-Unit, G3/8, 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator supplied together as one conditioning set. This GC40010LC2WGK is the 400 size with G3/8 ports in G (BSPP) thread. The filter stage carries the 5 um element (code W) with a differential-pressure drain, the regulator is the low-pressure type fitted with an external round gauge scaled in psi, and a reverse/check valve (K) is fitted. Bowls are polycarbonate at this size, and the mounting bracket is included.
This is a genuine AirTAC part. The GC family spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge style and scale, PT, G or NPT threads, and standard or low-pressure regulators. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet for your application.

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". |
| (blank) | Drain: Differential-pressure 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. |

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.

Conditioned air for the gripper and pusher cylinders on a bottling conveyor: 5 um filtration protects seals from grit and water, the low-pressure regulator suits sensitive actuation, and the lubricator feeds a steady oil mist to keep cylinders and valves running smoothly.
Feeds impact wrenches and nut runners at an assembly bench. The lubricator delivers a continuous oil mist for the air motors, the 5 um element keeps abrasive particles out of the tools, and the round psi gauge lets operators set and check line pressure at a glance.
Supplies filtered, regulated and lubricated air to pneumatic clamps and swing cylinders in a robotic weld cell. The reverse/check valve protects the downstream circuit if supply is interrupted, and the differential-pressure drain handles condensate without a manual drain valve.
Size and port step up with flow demand: 200, 300, 400 and 600 map to larger ports, and this unit sits at 400 with G3/8 in G thread (PT is the standard thread; G and NPT are order options). The drain is differential-pressure here, with automatic (A) and manual (M) available; filtration is 5 um (W) against the 40 um standard. The gauge is the external round type scaled in psi; an embedded square gauge is standard, with MPa, psi or bar scales. The regulator is the low-pressure type (L) with a reverse/check valve (K) fitted, and the mounting bracket is included. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing from 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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes GC-series flow as performance curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and other datasheet figures for the GC40010LC2WGK on request.
The L in GC40010LC2WGK marks the low-pressure regulator type. Its exact adjustment range is not published in the catalogue data we work from, so we confirm it on request rather than quoting a figure. If your line needs the standard adjustment range instead, the same 400 size is available without the L code.
