The AirTAC GC300C15MC2WGK 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator built as one air-preparation set. This GC300C15MC2WGK is a size 300 unit with a G1/2 (BSPP) port. The filter carries the fine 5 um element (the W option; 40 um is the standard grade) and the bowl has a manual drain, so condensate is released by opening the drain during service checks. The regulator is the standard type with a 0.05-0.9 MPa (7-130 psi) adjustment range, and the set includes a round pressure gauge reading in psi. A reverse/check valve (code K) is fitted and a mounting bracket is included. The polycarbonate bowls are rated for a maximum inlet pressure of 1.0 MPa (145 psi) and operation from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and with choices of drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge style and scale (MPa, psi or bar), thread (PT standard, with G and NPT as order options) and reverse/check valve. AirTAC publishes flow for this series as curves rather than a single rated figure, so ask us and we will confirm the flow and datasheet figures 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: GF300-C1 filter, GR300-C1 regulator and GL300-C1 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 machining centres where pneumatic clamps, tool changers and parts-blow-off circuits all draw from one drop: the filter removes water and fine particulate, the regulator holds the set pressure, and the lubricator oils the valve and cylinder seals.
Installed ahead of carton sealers, case packers and labelling heads so the cylinders and grippers on the line receive clean, regulated, lubricated air, with the check valve holding the circuit against backflow when upstream pressure dips.
Powering impact wrenches, air ratchets and nutrunners at assembly stations: the 5 um element keeps water and debris out of the tools, the regulator pins the working pressure, and the oil-mist lubricator keeps the air motors running smoothly.
Size 300 with a 1/2 inch port sits in the middle of the GC range (200/300/400/600); step up or down a size when your flow demand or existing piping calls for it. The decodable choices on this set are already fixed: 5 um filtration for cleaner air than the 40 um standard element, a manual drain instead of automatic or differential-pressure, a round gauge scaled in psi, a G (BSPP) thread instead of PT or NPT, and a fitted reverse/check valve. Because AirTAC publishes flow for the G series as curves rather than a single rating, ask us to confirm sizing against your application 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 GR300-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for the G series as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow from the datasheet and help you check this size 300, G1/2 unit against your air demand.
The M in the code sets a manual drain on the filter bowl: condensate is released by opening the drain when you service the unit, rather than being expelled automatically. With a manual drain the regulator adjustment range is 0.05-0.9 MPa (7-130 psi); automatic and differential-pressure drain versions are rated 0.15-0.9 MPa (20-130 psi).
