The AirTAC GC300C10F2WK AirTAC F.R.L. Combination Unit, PT3/8 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 GC300C10F2WK is an AirTAC GC series three-unit F.R.L. combination: a separate filter, regulator and lubricator that remove water and particulate from compressed air, hold a set downstream pressure and add oil mist for downstream valves, cylinders and air tools. This configuration is built for PT3/8 (3/8 in) lines with a 5 um filter element (the W grade, finer than the standard 40 um), a differential-pressure drain on the filter bowl, a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi), an embedded square gauge reading in psi, and a reverse/check valve fitted to hold downstream pressure if the supply drops. A mounting bracket is included, and the unit is rated for -5 to 70 C (non-freezing) service at up to 1.0 MPa (145 psi) max inlet pressure; the size 300 bowls are polycarbonate (only size 600 uses aluminium alloy).
This is a genuine AirTAC part. The GC series covers four sizes (200/300/400/600) with ports from 1/8 to 1 in, available as separate filter, regulator and lubricator units or as this three-piece set, with choices of thread (PT standard; G and NPT as catalogue options), drain type, filter grade, gauge type and scale, and reverse/check valve. Flow is published as curves rather than a single rated figure, so send us your line pressure and air demand and we will confirm the sizing and datasheet figures 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.

Feeds filtered, regulated and lubricated air to a machining centre's pneumatic clamps, tool-changer actuators and chip-clearing nozzles from a PT3/8 drop, with the 5 um element protecting fine control valves.
Supplies a carton-forming and case-sealing conveyor section with clean, pressure-stabilised, oil-misted air so case-erector and sealing cylinders run smoothly through continuous shifts.
Conditions the air at an assembly-cell drop serving pneumatic nutrunners, grippers and clamping fixtures, with the reverse/check valve helping hold the set pressure if the main supply dips.
Work through the decodable choices before ordering. Size and port: 300 is the mid size with a PT3/8 port; step up to 400 or 600, or down to 200, if your demand sits near the edge of the 3/8 in flow curve. Drain: this unit carries the differential-pressure drain (the default); automatic (A) and manual (M) versions exist where a pressure differential cannot be relied on to clear water. Filter grade: the W code fits a 5 um element instead of the standard 40 um - choose 5 um for sensitive valves and cylinders, 40 um where coarser protection is enough. Gauge: the F2 code gives the embedded square gauge with a psi scale (MPa and bar scales are alternatives, and an external round gauge is optional). Thread: PT is the standard; G (BSPP) and NPT are order options. A mounting bracket is included, and the K code means a reverse/check valve is fitted. One honest note: AirTAC publishes flow as curves, not a single rated figure, so ask us to confirm sizing 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-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 there is no one figure we can quote honestly. Tell us your working pressure, downstream air demand and allowable pressure drop, and we will confirm the flow from the datasheet on request before you order.
W selects the 5 um filter element in place of the standard 40 um grade, giving finer filtration for sensitive valves, cylinders and tools. The rest of the code reads: 300 size, PT3/8 port, PT thread, differential-pressure drain, embedded square gauge with psi scale, standard regulator, and a fitted reverse/check valve.
