The AirTAC GC300C08F2WK 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 GC300C08F2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one set, giving you filtration, pressure regulation and oil-mist lubrication in a single PT1/4 (1/4 in) connection. This configuration carries the 5 um filter element (code W) for finer water and particulate removal than the 40 um standard, a standard-type regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, a differential-pressure drain on the filter bowl, and a reverse (check) valve fitted. The pressure gauge is included, and the set comes with a mounting bracket. Max 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 port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge scale and thread (PT standard; G and NPT are order options). Flow is published by AirTAC 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.

Feeds spray-gun drops on a paint line where the 5 um element removes water and particulate ahead of the regulator and the lubricator mists oil to the guns.
Supplies filtered, regulated and lubricated air to directional valves and cylinders on carton-forming and case-packing conveyors, with the check valve holding the set pressure.
Conditions the shop-air feed to a machining centre's pneumatic tool-change and clamping circuits, with the 5 um grade protecting downstream components.
Choose the size and port step against the air demand of the circuit: the 300 size with its PT1/4 port sits in the middle of the GC range, which steps up through 400 and 600 for larger ports and higher flow. Pick the drain type where it applies: differential-pressure (this unit's default), automatic for unattended draining, or manual where an operator drains the bowl on a schedule. Select the filter grade: 40 um standard or 5 um (this unit, code W) for finer filtration. Set the gauge scale - MPa, psi or bar - and decide between the embedded square gauge and the optional external round gauge. Thread is PT as standard, with G (BSPP) and NPT available to order.
One honest note on sizing: AirTAC publishes flow for these units as curves, not as a single rated number, so we do not quote a flow figure here. Ask us to confirm the flow curve and datasheet against your application 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 number here. Ask us and we will confirm the flow curve and datasheet for the 300 size at PT1/4 against your application before you order.
The W in the code GC300C08F2WK selects the 5 um element, which removes finer water and particulate than the 40 um standard element. Choose 5 um where downstream valves, cylinders or tools need cleaner air; the 40 um grade remains the standard choice for general-purpose lines.
