The AirTAC GC300C10C2K AirTAC F.R.L. Combination, PT3/8 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 GC300C10C2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one complete air-treatment set. This size GC300 unit carries a 3/8 in PT port, a 40 um standard filter element with a differential-pressure drain on the filter bowl, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). The C2 code adds an external round gauge with a psi scale, and the K code means a reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with a choice of ports, thread types (PT standard, G and NPT as order options), drain types, filter grades (40 um standard, 5 um with code W) and gauge scales. Flow figures are published as curves rather than a single rating, so we 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-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 filtered, regulated and lubricated air to the actuators, clamps and tool-change cylinders on a machining centre, with the psi gauge giving operators a local pressure readout at the cell.
Conditioning the air feeding conveyor stopper cylinders, diverters and case-sealing actuators on a packaging line, where the check valve holds the set pressure if the main supply drops.
A complete F.R.L. set at the air drop for a manual assembly bench, cleaning the shop air, holding a stable regulated pressure for air tools and screwdrivers, and carrying oil mist to keep them running.
Size 300 with a 3/8 in PT port sits in the middle of the GC range: step up to 400 or 600 for larger ports and higher flow demand, or down to 200 for compact lines. The differential-pressure drain on the filter bowl is the default and suits installations where the unit sees a regular pressure differential; an automatic drain (code A) or a manual drain (code M) can be ordered instead. The 40 um element is the standard grade; specify code W for the 5 um element where finer particulate removal is needed. The round gauge here reads in psi; square embedded gauges and MPa or bar scales are the other catalogue choices. Thread is PT as standard - order G (BSPP) or NPT if your piping needs it. A mounting bracket is included, and the fitted check valve (K) holds downstream pressure when the upstream supply is removed.
Because flow is published as curves rather than a single rated figure, 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 rather than a single rated figure, so there is no one rated flow number we can quote. Send us your application details and we will confirm the relevant flow and datasheet figures for this size 300, 3/8 in unit on request before you order.
C is the round external gauge option (the embedded square gauge is the standard fitting), 2 sets the gauge scale to psi, and K means a reverse/check valve is fitted so downstream pressure is held when the upstream supply is removed. The base code GC300-10 covers the size 300 three-unit F.R.L. set with a 3/8 in PT port.
