The AirTAC GC300C15MC2GK AirTAC F.R.L. Combination, 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 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 set up as one complete air-treatment train. This configuration, the GC300C15MC2GK, is the size 300 unit with a G1/2 (1/2 in) port and G thread, a 40 um standard filter grade, a manual drain on the filter bowl, and a reverse/check valve fitted. Regulation is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the external round gauge fitted to this code reads in psi. The lubricator mists oil into the downstream air for tools and actuators that need it. Maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port options, thread choices (PT standard; G and NPT as order options), drain types (differential-pressure, automatic or manual), a 5 um (W) filter grade option, gauge styles and scales, 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 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: 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.

A filtered, regulated and lubricated supply for impact wrenches, nut runners and air ratchets at assembly stations, with the round psi gauge letting line staff verify set pressure at a glance and the check valve holding the circuit if the main supply drops.
Clean, regulated and lubricated air for tool-clamp cylinders, chip-clearing blow-off and pneumatic clamping on machining centres, where the 40 um grade protects valves and the regulator holds a steady clamp pressure.
Conditioned air for case-erectors, carton sealers and conveyor diverters, with the lubricator oil-misting the cylinders that cycle all shift and the manual-drain filter bowl emptied during scheduled line cleaning.
Start with the size and port: the GC series steps through sizes 200, 300, 400 and 600, and the port grows with the size (here 1/2 in on the size 300 body), so match the step to the air consumption of the machines downstream - we can confirm the flow curve against your demand on request. Choose the drain type on the filter: manual (as on this code) needs periodic draining by hand, while automatic and differential-pressure drains remove condensate without attention. Choose the filter grade: 40 um is standard and suits general plant air; the 5 um (W) option suits finer downstream equipment. Pick the gauge style and scale (embedded square or external round; MPa, psi or bar - this code carries an external round gauge reading psi), and decide whether the reverse/check valve (fitted here) is wanted to hold downstream pressure on supply loss. Select the thread: PT is the standard; G (BSPP) and NPT are catalogue options to order. A bracket is included on this code. Because flow is published 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 GC series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details and we will confirm the flow curve and datasheet figures for the size 300, 1/2 in port unit against your actual air demand before you order.
The M in the code sets the filter bowl drain to manual type: condensate collects in the bowl and someone drains it by hand at intervals. The GC family also offers automatic and differential-pressure drains that remove condensate without attention, so if the unit will be mounted somewhere hard to reach, ask us about those variants instead.
