The AirTAC GC40010MLC2G AirTAC F.R.L. Combination, G3/8 (3/8 in) 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 GC series is AirTAC's three-piece F.R.L. combination: a separate filter, pressure regulator and oil-mist lubricator, so each stage can be inspected and serviced on its own. This GC40010MLC2G is the size 400 unit with a G3/8 (3/8 in) G-thread port. The filter stage carries the standard 40 um element with a manual drain, the regulator is the low-pressure type, and the set is fitted with an external round gauge scaled in psi. The bowls are polycarbonate, the reverse/check valve is not fitted, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options including automatic or differential-pressure drains, a 5 um filter element (code W), square or round gauges with MPa, psi or bar scales, PT, G or NPT threads, and a reverse/check valve. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure against 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.
| 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. |

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 filtered, regulated and lubricated air to the clamps and small presses on an assembly cell, with the low-pressure regulator set to the circuit's working pressure and the 40 um element keeping scale out of the valves.
Supplies the cylinders and actuators that drive diverters, pushers and packaging heads, removing water and particulate at the drop while the lubricator mists the cylinders to reduce seal and bore wear.
A service drop from the shop compressor feeding impact wrenches, ratchets and air drills, where the filter protects the tools from contamination and the oil-mist lubricator keeps them running smoothly.
Choose the size by the port and flow step: size 400 sits mid-range with its 3/8 in port, and you step up or down a size as your line's air demand changes. Where a bowl is present you pick the drain: differential-pressure (the default), automatic (code A) or manual (code M) as here - a manual drain means someone opens it periodically to discharge collected water. The filter element is 40 um standard or 5 um with code W. Gauges are an embedded square gauge as standard or an external round gauge, with MPa, psi or bar scales - this unit carries the round psi gauge. Threads come as PT (the standard), with G or NPT as order options; brackets are optional on most units and included here.
Because flow is published as curves rather than a single rating, we do not quote a rated flow number - send us your working pressure and air demand and we will confirm sizing and the datasheet figures 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 flow for this series as curves, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet before you order.
It marks the low-pressure type of regulator rather than the standard version. The exact adjustment range for this variant is not published in the material we hold, so we confirm it with the datasheet on request. The rest of the code decodes as: size 400, G3/8 port, G thread, manual drain, 40 um filter, round psi gauge, no reverse/check valve, bracket included.
