The AirTAC GC40010MC2GK 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 GC40010MC2GK is an AirTAC GC three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-treatment set for compressed air. This configuration is size 400 with a G3/8 (3/8 in) G-thread port. It filters water and particulate down to 40 um, regulates downstream pressure over 0.05-0.9 MPa (7-130 psi) with the standard regulator, and adds oil-mist lubrication for downstream components. The drain is manual (code M), the pressure gauge is the round external type with a psi scale, and a reverse/check valve (code K) is fitted. Maximum working (inlet) pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing. The filter and lubricator bowls are PC (polycarbonate) at this size; a mounting bracket is included.
This is a genuine AirTAC part. The GC line is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um filter grade (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet figures 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 0.05 - 0.9 MPa (7 - 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: GF400-10 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.

Installed at the point where the workshop ring main drops down to a CNC machining cell, the set cleans water and 40 um particulate from the compressed air, holds a set working pressure for the machine's air circuit, and feeds oil mist to its pneumatic actuators.
Mounted on the supply line feeding the air cylinders and grippers of a packaging or palletising conveyor, the combination keeps regulated pressure stable through shift changes and lubricates the cylinders, while the manual drain is emptied during planned line stops.
Fitted at the wall outlet feeding a maintenance workshop's air tools, impact wrenches and test rigs, the unit removes water and dirt, lets the technician dial in working pressure on the psi gauge, and oils the tools, with the check valve holding the set-up between uses.
Size 400 with a G3/8 (3/8 in) port suits lines that need more flow than the 200/300 step; step up to 600 or down to 300 against your demand, and we will confirm sizing from the published flow curves before you order. The manual drain (code M) means an operator or a scheduled routine drains each bowl - choose automatic or differential-pressure drain if nobody is at the machine. The 40 um standard filter grade covers general plant air; specify the 5 um W grade where finer filtration is needed. The round gauge here reads in psi; MPa and bar scales are also available. The G (BSPP) thread is the order option in this code - PT is the standard thread and NPT is also available. A mounting bracket is included, and the reverse/check valve is fitted.
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 number, so there is no one figure we can honestly quote. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet curves on request before you order.
The M in the code specifies a manual drain: the bowls are emptied by hand on a schedule. If the unit will be mounted where nobody regularly attends it, the same GC400 series can be ordered with an automatic (code A) or differential-pressure (blank) drain instead - the manual-drain version also carries the wider 0.05-0.9 MPa (7-130 psi) regulation range.
