The AirTAC GC40010MLC2GK AirTAC F.R.L. Combination, G3/8 Port 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC40010MLC2GK is a genuine AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 400-size unit for a G3/8 (3/8 inch) G-thread port. This configuration carries the standard 40 um filter element with a manual drain bowl in polycarbonate, a low-pressure-type regulator fitted with an external round gauge scaled in psi, and a reverse/check valve. It filters water and particulate from compressed air, holds a set downstream pressure and adds oil mist for downstream air tools.
This is a genuine AirTAC part in the GC size range (200/300/400/600), with port sizes, thread options (PT standard; G and NPT to order), drain types, 40 um or 5 um filter grades and gauge scales available across the family. Flow is published as curves rather than a single rated figure, so we 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. 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.
| GC400 | G-series F.R.L. combination, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Feeding filtered, regulated and lubricated air to the tool-clamp and pallet-change circuits of a CNC machining centre, with the psi gauge giving the operator a direct reading at the machine.
Conditioning the air feeding cylinders and grippers on a carton-forming and sealing conveyor line, where the lubricator keeps seal-less actuators running through long shifts.
A wall-mounted air preparation drop serving pneumatic screwdrivers and clamps at an assembly bench, with the manual drain emptied as part of the daily start-up routine.
Size 400 with a G3/8 port is the mid-large step in the GC range; step up or down (200/300/400/600) to match the pipe size and flow demand of the line. This unit is the low-pressure regulator type, so choose it where the working pressure sits below the standard regulator's range; the exact low-pressure adjustment range is not published, so confirm it with us. The manual drain bowl needs periodic hand draining, unlike the automatic or differential-pressure drain options. The 40 um element is the standard grade; specify the W code for 5 um where finer filtration is needed. The fitted round gauge is scaled in psi (MPa and bar scales are alternatives), and the G thread is an order option against the PT standard.
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, not as a single rated figure, so we do not quote a l/min or SCFM number. Send us your line pressure and downstream demand and we will confirm the correct size against the datasheet curves on request before you order.
The M in the code selects the manual drain bowl, which you empty by hand rather than relying on an automatic or differential-pressure drain. The L selects the low-pressure regulator type, intended for working pressures below the standard range; the exact adjustment range is not published, so confirm it with us. The C2 adds the external round gauge scaled in psi, and K fits the reverse/check valve.
