The AirTAC GC300C08C2WK 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 GC300C08C2WK is an AirTAC GC three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-preparation set for 1/4 in (PT1/4) compressed-air lines. The filter element is the fine 5 um grade (the standard element is 40 um, this unit is ordered with W), the bowl drains by differential pressure, and the regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi). The C2 code adds an external round gauge with a psi scale, a reverse/check valve (K) is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GC family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and in PT, G (BSPP) and NPT thread options, with a choice of drain type, filter grade, gauge style and scale, and reverse valve. Max inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Feeds clean, regulated, lubricated air to the tool-change clamps and pneumatic actuators on a machining centre, with the 5 um element protecting fine-control valves on the machine's air circuit.
Prepares the air feeding conveyor diverters, case-erector cylinders and sealing heads on a packaging line, where the regulator holds a steady setting through shift-long cycling and the lubricator mists the cylinder seals.
Conditions the air at the drop to a finishing booth or spray rig, using the 5 um filtration stage ahead of regulation and lubrication so the downstream equipment on the line receives treated air.
Start with the port step: this unit is size 300 with a 1/4 in PT port; if your line needs more flow, step up to size 400 or 600, and down to 200 for compact circuits. Choose the drain type to suit access: differential-pressure (as fitted here, drains automatically on a pressure drop), automatic (A), or manual (M). Choose the filter grade: 40 um standard for general protection, 5 um (W, as here) for finer downstream protection - a lubricator follows the filter in this set, so element choice matters for the whole downstream circuit. Gauge options are the embedded square gauge or an external round gauge, with MPa, psi or bar scales - this unit carries a round psi gauge. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. A reverse/check valve (K) is fitted on this unit, and the bracket is included.
Because flow is published as curves and not as a single rated figure, send us your application details and we will confirm sizing against the datasheet 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-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 rated flow, Cv or SCFM number for this unit. Send us your line pressure and the flow your application needs, and we will confirm the sizing against the datasheet curves before you order.
The W in the code GC300C08C2WK orders the optional 5 um filter element instead of the 40 um standard. The 5 um grade gives finer removal of water and particulate, which is the usual choice where sensitive valves, cylinders or downstream equipment need cleaner air. If your circuit only needs general protection, the 40 um standard grade is available in the same size.
