The AirTAC GC300C08AC2GK AirTAC F.R.L. Combination, G1/4 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 GC300C08AC2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator set up as one treatment train. This configuration is built for a G1/4 (1/4 in) port with G thread, carries a 40 um filter element, and uses an automatic drain on the filter bowl so collected water is expelled without manual attention. The standard regulator adjusts across 0.15-0.9 MPa (20-130 psi) and a round gauge on a psi scale is fitted so downstream pressure can be read and set directly. A reverse/check valve is included, and the set comes with a mounting bracket for panel or wall fixing. 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 offered in sizes 200, 300, 400 and 600 with matching port sizes, and each element can be specified with drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard; G and NPT as order options) and bracket choices. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm the datasheet and sizing 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-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.

Feeds spray guns and air-assisted applicators on a paint line, where the filter removes water and particulate, the regulator holds a steady set pressure, and the lubricator mists oil to keep gun spindles and air motors running smoothly.
Supplies the pneumatic cylinders and air clamps on a packaging conveyor, giving the machine one point where clean air, a fixed working pressure and cylinder lubrication are all set and visible on the psi gauge.
Conditions the air feeding a machining centre's clamping fixtures and tool-change actuators: the 40 um filter and automatic drain protect the valves, the regulator locks clamp pressure, and the lubricator conditions the actuator seals.
Start with the size and port step: GC300 with a 1/4 in port suits compact supply drops; step up to GC400 or GC600 when the line demands larger ports and more flow, or down to GC200 for small circuits. Choose the drain on the filter bowl: automatic (as here) empties condensate unattended, manual needs an operator, and differential-pressure draining suits lines where a pressure signal is preferred. Filter grade is 40 um as standard; specify the W code for 5 um where finer particulate removal matters. Pick the gauge style and scale (square embedded or external round; MPa, psi or bar) to match how your technicians set pressure. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the bracket can be kept or omitted. Because AirTAC publishes flow as curves rather than a single rating, ask us to confirm the 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 GC series as curves rather than a single rated figure, so there is no one l/min, m3/h or SCFM number we can state. Tell us your line pressure and the air demand of your equipment and we will confirm the sizing from the datasheet on request.
The A in the code GC300C08AC2GK means the filter bowl drains itself automatically, so condensate is expelled without an operator opening a valve - useful on lines that run unattended. The GC family also offers manual and differential-pressure drain versions if you prefer a different arrangement.
