The AirTAC GC300C08C2K AirTAC F.R.L. Combination, PT1/4 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 GC300C08C2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one treatment stack. This 300-size unit is configured with a PT1/4 (1/4 in) port, a differential-pressure drain on the filter bowl, the standard 40 um filter element, a round pressure gauge reading in psi, a reverse/check valve fitted on the regulator, and a mounting bracket included. It filters water and particulate from compressed air, holds a set downstream pressure, and adds oil mist for air-tool lubrication in one assembly.
This is a genuine AirTAC part. The GC family is available in 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, thread options PT (standard), G and NPT, drain choices (differential-pressure, automatic or manual), a 5 um filter element option, gauge scales in MPa, psi or bar, and an optional reverse/check valve. Flow figures are published as curves rather than a single rating, so we confirm the datasheet and sizing 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-C0 filter, GR300-C0 regulator and GL300-C0 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 clean, regulated and lubricated air to the tool-changer and clamping actuators on a CNC cell, with the check valve holding the set pressure against upstream fluctuation.
Conditioning the air feeding carton-forming and case-sealing cylinders on a packaging conveyor, where the lubricator keeps cylinder seals running smoothly through long shifts.
Installed at a workshop air drop serving impact wrenches and air ratchets, filtering condensed water and particles, regulating working pressure and delivering oil mist to the tools.
Step up or down through the 200/300/400/600 size range to match the port and flow path your line needs; the 300 size carries the PT1/4 port decoded here. Choose the drain type where the unit is installed: differential-pressure (this configuration), automatic for unattended drains, or manual for periodic service. The standard element is 40 um; specify the 5 um option (code W) where finer filtration is required. Gauge scale is selectable (MPa, psi or bar - this unit is psi), the reverse/check valve (K) is fitted here, and PT is the standard thread with G and NPT available as order options.
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-C0 regulator with a GF300-C0 filter on that branch.
AirTAC publishes flow for the GC300 as curves rather than a single rated figure, so there is no one rated-flow number we can quote. Tell us your application and required flow, and we will confirm the correct size from the datasheet on request before you order.
C is the round external pressure gauge, 2 sets its scale to psi, and K means a reverse/check valve is fitted on the regulator. The unit also carries the standard configuration: PT1/4 port, PT thread, differential-pressure drain, 40 um filter element and an included mounting bracket.
