The AirTAC GC40015C2K AirTAC F.R.L. Combination, PT1/2 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 GC40015C2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one F-R-L set. This configuration is built on the size 400 body with PT1/2 ports (PT thread standard; G and NPT are order options), a 40 um filter element, a differential-pressure drain on the filter bowl, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, and a round gauge with a psi scale. A reverse/check valve is fitted, and the set includes a mounting bracket. The filter and lubricator bowls are polycarbonate (PC); only size 600 units use aluminium alloy bowls.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600, with choices of port size and thread, drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge style and scale, and a reverse/check valve option. Flow is published as curves rather than a single rated figure, so ask us to 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. 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 a filtered, regulated and lubricated air supply to impact wrenches and nutrunners at assembly stations, with the psi round gauge letting line staff read set pressure at a glance.
Conditions the air feeding carton sealers and wrapping equipment on a packaging line, removing water and particulate, holding steady regulator pressure and oil-mist lubricating the machine's air cylinders.
Installed at workshop air take-off points so technicians draw clean, regulated, lubricated air for air tools and test rigs, with the check valve helping hold the downstream circuit's set-up.
Work from the size and port first: size 400 with PT1/2 ports sits in the middle of the GC range (200/300/400/600), so step up or down depending on the air demand of the line and the pipe size you are connecting to. Because rated flow is published only as curves, ask us to confirm sizing against your application before ordering. Then settle the decodable options: drain type on the filter bowl (differential-pressure as fitted here, automatic, or manual), filter grade (40 um standard, 5 um with code W for finer filtration), gauge style and scale (this unit carries a round gauge with a psi scale; an embedded square gauge with MPa/psi/bar scales is the standard alternative), thread (PT standard, G or NPT to order), and the reverse/check valve (fitted on this unit, code K). A mounting bracket is included.
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 this family as curves rather than a single rated figure, so we do not quote a flow number. Send us your air demand and line conditions and we will confirm the sizing from the datasheet on request before you order.
The C2 in the code specifies a round external gauge with a psi scale; the standard alternative is an embedded square gauge with MPa, psi or bar scales. The trailing K means a reverse/check valve is fitted, which helps hold the downstream pressure setting. Both are catalogue options you can specify on other GC units.
