The AirTAC GC40010C2GK AirTAC F.R.L. Combination, G3/8 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40010C2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This size 400 unit carries G3/8 (BSPP) ports and conditions compressed air in three stages: the filter removes water and particulate down to 40 um, the regulator holds downstream pressure anywhere in its 0.15-0.9 MPa (20-130 psi) adjustment range, and the lubricator feeds an oil mist to downstream tools and actuators. The filter bowl is polycarbonate with differential-pressure drainage, an external round gauge with a psi scale is fitted, a reverse/check valve is installed, and a mounting bracket is included.
This is a genuine AirTAC part, supplied by a distributor for the US market. The GC family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including automatic or manual drains, a 5 um filter element, gauge scale choices and G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 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.

Feeding filtered, regulated and lubricated air to a workshop pneumatic press, with the check valve holding the set pressure if upstream supply dips mid-stroke.
Conditioning the air supply to cylinders and grippers on a carton packaging conveyor, keeping moisture and debris out while metering oil mist to the actuators.
Supplying air tools at a bench assembly station, where the psi gauge lets operators set and monitor working pressure and the lubricator keeps tool motors running smoothly.
Size 400 with G3/8 ports sits in the middle of the GC range: step up to size 600 for larger porting and more flow, or down to 200/300 where the demand is smaller. The regulator covers 0.15-0.9 MPa (20-130 psi) on this standard type. Drainage here is differential-pressure, which discharges automatically as the pressure differential across the filter changes; automatic (A) and manual (M) drains are orderable alternatives. The filter element is the 40 um standard grade; the 5 um grade (code W) is available if finer filtration is needed. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue choices. Thread is G (BSPP); PT is the standard thread and G/NPT are order options. Flow is published as curves, not a single rated figure, so have us confirm sizing against your line 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 there is no one rated flow number to quote. Tell us your line pressure and air demand and we will confirm the relevant datasheet curve figures for this unit on request.
C2 means an external round gauge with a psi scale is fitted (the embedded square gauge is the standard option, with MPa or bar scales available). K means a reverse/check valve is installed, which prevents downstream pressure loss if the upstream supply drops. This unit also carries G (BSPP) threads; PT is the standard thread and NPT is an orderable option.
