The AirTAC GC300C15C2WGK AirTAC F.R.L. Combination, G1/2, 5 um 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 GC300C15C2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package. This configuration is built for a 1/2 in port with G (BSPP) threads, carries the fine 5 um filter element (code W), drains the filter bowl by differential pressure, and is fitted with an external round gauge scaled in psi plus a reverse/check valve on the regulator. A mounting bracket is included, and the filter and lubricator bowls on this unit are metal. In use it cleans water and particulate from the compressed air, holds a set downstream pressure adjustable from 0.15 to 0.9 MPa (20 to 130 psi), and adds a controlled oil mist for downstream air tools and cylinders.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with a choice of ports, thread forms (PT standard; G and NPT as order options), drain types, 40 um or 5 um filtration, gauge style and scale, and check-valve fitment. Rated flow for this series is published as curves rather than a single figure, so ask us and we will 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-C1 filter, GR300-C1 regulator and GL300-C1 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.

Installed at the machine inlet on a CNC lathe or machining centre, the unit dries and filters the shop air to 5 um, holds a steady regulated pressure for clamping and tool-change circuits, and mists oil to the machine's air-powered components.
Mounted beside a cartoning or case-packing conveyor, the combination feeds the line's air cylinders: clean, regulated air for consistent stroke timing, and lubrication for the valves and cylinders running through multiple shifts.
Fitted at the drop point in a paint or finishing booth area, the unit removes water and fine particulate before the regulator, keeps spray-gun supply pressure stable, and can feed a light oil mist to air-driven agitators and tools.
Size this combination by the port and flow step first: size 300 with a 1/2 in port sits in the middle of the GC range (200/300/400/600), so step up or down if your line's air demand points to a different port. Choose the filter grade deliberately: 40 um is the standard element, while this unit's 5 um (W) element suits finer protection downstream. Drain type is a real choice across the range - differential-pressure (as fitted here), automatic, or manual - and the gauge can be specified embedded square or external round, scaled in MPa, psi or bar; this unit carries a round psi gauge. Thread is PT as standard with G (BSPP) and NPT available to order, and the check valve (K) prevents downstream backflow through the regulator. Because flow for this series is published as curves and not a single rating, 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-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated number, so we do not quote one figure. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The W in the code GC300C15C2WGK specifies the fine 5 um filter element instead of the standard 40 um, giving finer protection for downstream equipment. The trailing K specifies a reverse/check valve fitted on the regulator, which blocks backflow through the unit. Both are order-time choices across the GC range, along with drain type, gauge style and scale, and PT, G or NPT threads.
