The AirTAC GC30015AC2GK AirTAC F.R.L. Combination, G1/2 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015AC2GK is a three-piece AirTAC F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one unit. It cleans compressed air of water and particulate down to 40 um, regulates downstream pressure within a 0.15-0.9 MPa (20-130 psi) range, and adds oil mist to the air supply for downstream pneumatic tools and actuators. This configuration is fitted with a 1/2 in port in G (BSPP) thread, an automatic drain on the filter bowl, a polycarbonate bowl, a round external gauge with a psi scale, and a reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GC series, which covers sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), filter grades (40 um standard, 5 um optional), gauge styles and scales, and thread options. Flow figures for the GC300 are published as curves rather than a single rated number, so ask us to confirm the datasheet 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: GF300-15 filter, GR300-15 regulator and GL300-15 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.

A filtered, regulated and lubricated air drop feeding impact wrenches, nutrunners and air cylinders on an automotive or appliance assembly line, where one unit conditions the whole station supply.
Conditioning the air feeding carton sealers, case packers and bagging machines, where clean, pressure-stable and lubricated air keeps cylinders and grippers cycling reliably shift after shift.
Supplying spray guns and coating equipment in a finishing booth, where the filter removes water and 40 um particulate before the regulator sets a stable working pressure for consistent atomisation.
Sizing a GC combination starts with the port step: this unit is size 300 with a 1/2 in port, and larger sizes carry larger ports and more flow capacity - match the size to the air demand of the circuit rather than the pipe alone. Because flow is published as curves and not as a single rated figure, ask us to confirm sizing against your application before ordering. The remaining choices are decodable from the code: the automatic drain here discharges collected condensate without manual attention (a manual-drain variant would also widen the regulator's low-end adjustment to 0.05 MPa), the 40 um grade suits general pneumatic supply (a 5 um W-code element is available where finer filtration is needed), and the round psi gauge can be swapped for an embedded square gauge or an MPa/bar scale. G thread is a catalogue option ordered in place of the PT standard, and the 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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC publishes flow for the GC300 as curves rather than a single rated figure, so we do not quote a rated flow number. Ask us to confirm the datasheet flow figures for your application on request, and we will check the curve against your air demand before you order.
A is the drain code: this unit has an automatic drain that discharges condensate from the filter bowl without manual intervention (the default is differential-pressure drain, and M would be manual). C2 is the gauge code: an external round gauge with a psi scale is fitted; an embedded square gauge is the standard alternative, with MPa or bar scales also available.
