The AirTAC GC300C08ALF2GK AirTAC F.R.L. Unit, G1/4, Auto Drain 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 assembled as one air-preparation set. This size 300 unit has a G1/4 (BSPP) port. The filter carries a 40 um element with an automatic drain, so collected water is expelled without manual intervention. The regulator is the low-pressure type and is fitted with an embedded square gauge scaled in psi. A reverse (check) valve is fitted and the set includes a mounting bracket. The filter and lubricator bowls are polycarbonate at this size. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating 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 ports from 1/8 to 1 inch, and options include a 5 um filter element (code W), manual or differential-pressure drain, gauge scales in MPa, psi or bar, and G or NPT thread in place of the PT standard. 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-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.

Conditions the supply to pneumatic clamps and tool-change cylinders on a machining centre: the 40 um element strips water and swarf-carried particulate, the low-pressure regulator holds a steady setting for clamping, and the lubricator mists oil to the actuators.
Feeds spray guns and air-assisted applicators where a low-pressure regulator setting and clean, dry air matter. The 40 um filter removes water and particles that ruin finishes, and the automatic drain keeps the bowl clear during continuous booth operation.
Sits at the drop of a packaging or carton-forming conveyor to condition air for cylinders and air-driven grippers, with the lubricator feeding moving seals and the automatic drain suiting lines that run unattended across shifts.
Choose the size by port and demand: size 300 with a 1/4 in port suits compact circuits, while 400 or 600 serve higher demand. The filter drain is automatic on this unit; manual and differential-pressure versions are available. The standard element is 40 um; specify code W for the 5 um grade where finer filtration is needed. The embedded square gauge here reads in psi, with MPa and bar scales and an external round gauge as options. Thread is G (BSPP) on this unit; PT is the AirTAC standard and NPT is orderable. A mounting bracket is included and a reverse (check) valve is fitted. Flow is published as curves, not a single rating, so let us 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 GC series as curves, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The L marks the low-pressure regulator type; the exact adjustment range for this configuration is not published, and we confirm it on request. The A marks an automatic drain on the filter bowl, which expels collected water without manual intervention. The F2 in the code is the embedded square gauge scaled in psi, and the K is the fitted reverse (check) valve.
