The AirTAC GC40015C2GK AirTAC F.R.L. Combination Unit, G1/2 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 PT1/2" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC40015C2GK is a three-piece F.R.L. combination that cleans, regulates and lubricates compressed air at the point of use. The filter section removes water and particulate down to 40 um through a differential-pressure drain, 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. This unit is built around a G1/2 port, is rated to 1.0 MPa (145 psi) maximum inlet pressure, and operates from -5 to 70 C in non-freezing conditions. It is supplied with a round psi-scale gauge, a reverse/check valve fitted on the regulator, and a mounting bracket.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch and options including automatic or manual drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet numbers 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. 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: GF400-15 filter, GR400-15 regulator and GL400-15 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, pressure-regulated and lubricated air to spray booths and air-driven paint equipment on a finishing line, where clean, dry, correctly lubricated air protects finish quality and gun life.
Sits at the air inlet of a CNC machine tool or machining cell, conditioning the supply that actuates tool changers, clamps and pneumatic axes at a stable set pressure.
Conditions the air feeding cylinders and vacuum generators on a cartoning or palletising conveyor line, keeping seals and moving parts lubricated while holding line pressure steady.
Choose the GC size by the port and flow your line needs: this 400 size carries a 1/2 inch port, one step up from 3/8 and one down from 3/4. Drain type is a real choice - differential-pressure (as here, the default), automatic for unattended condensate removal, or manual where you bleed the bowl by hand. Filter grade is 40 um standard; specify the W code for 5 um when downstream equipment needs finer filtration. Gauge scale is selectable (MPa, psi or bar) and this unit carries the external round gauge in psi. Thread is PT as standard, with G and NPT available as order options - this unit is the G-thread version. A reverse/check valve (code K) holds the regulator setting if upstream pressure is lost.
Because flow is published only as curves and not as a single rated figure, ask us to confirm sizing against your air consumption 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and air consumption and we will confirm the correct sizing from the datasheet on request.
The K code in GC40015C2GK means a reverse/check valve is fitted, which holds the regulator setting if upstream pressure drops. The drain is the differential-pressure type (the default) and the filter element is the standard 40 um grade; automatic or manual drains and a 5 um element are available as order options.
