The AirTAC GC300C10MLC2G AirTAC F.R.L. Combination G3/8 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one unit. GC300C10MLC2G is built for G3/8 (3/8 in) ports with G (BSPP) thread. The filter stage carries the standard 40 um element with a manual drain, the regulator is the low-pressure type fitted with a round psi gauge, and the lubricator feeds oil mist to downstream equipment. The metal-bowled filter and lubricator sections mount on the included bracket, and the unit handles up to 1.0 MPa (145 psi) inlet at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include 5 um filtration (code W), automatic or differential-pressure drains, embedded square or external round gauges scaled in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet details 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.

Clean, regulated and lubricated air to the press clutch and cylinder valves on a stamping line, with the low-pressure regulator set to the actuation circuit's working pressure and read locally on the round psi gauge.
Treated air for diverters, grippers and seal jaws on a filling line: the 40 um filter keeps water and debris out of the directional valves while the lubricator mists the air cylinders that cycle all shift.
A bracket-mounted supply point feeding air tools and clamping fixtures at a workshop drop, giving one place to filter condensate, set circuit pressure and oil the tools downstream.
Size the unit by port and expected flow: this 300-size unit steps up to G3/8 (3/8 in), while the larger 400 and 600 sizes carry higher ports. Drain choice matters: this configuration uses a manual drain, which needs periodic bleeding, and automatic or differential-pressure drains can be ordered instead. Filtration is the standard 40 um grade; specify code W for 5 um where finer particulate capture is needed. The regulator here is the low-pressure type - its exact adjustment range is not published, so confirm it against your set pressure before ordering. Gauges can be ordered with MPa, psi or bar scales, and PT is the standard thread with G and NPT as order options. Because flow is published as curves, not a single rating, send us your flow and pressure requirements and we will confirm the correct size before you order.
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 performance curves rather than a single rated figure, so there is no one number we can quote. Send us your line pressure and required flow and we will confirm from the datasheet whether the 300 size at G3/8 suits your application.
This configuration uses a manual drain: condensate collected in the filter bowl must be bled off periodically. If you prefer, GC units can be ordered with an automatic or differential-pressure drain instead - just tell us which you want when ordering.
