The AirTAC GC300C10LF2WK 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 GC300C10LF2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-preparation set. This configuration is a size 300 unit with PT3/8 ports, fitted with the 5 um filter element (code W) for finer water and particulate removal, a differential-pressure drain on the filter bowl, a low-pressure-type regulator, an embedded square gauge with psi scale, and a reverse/check valve (code K). The mounting bracket is included. Medium is compressed air only; maximum 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 series is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades (40 um standard, 5 um optional), gauge styles and scales (MPa, psi or bar), and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm flow 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.

Feeding tool-clamp and actuator circuits on a machining centre: the 5 um element protects fine valves from water and swarf-laden condensate, the regulator holds a stable low set pressure, and the lubricator mists oil to the air tools downstream.
Conditioning air for the pick-and-place and sealing cylinders on a packaging conveyor: filtered, regulated and lubricated air from one PT3/8 drop keeps the cylinders and valve terminals running consistently through a shift.
A point-of-use F.R.L. set at an assembly-cell air drop: the filter drains accumulated condensate via the differential-pressure drain, the low-pressure regulator matches the cell's set pressure, and the check valve holds the circuit if the main supply dips.
Size 300 with PT3/8 ports suits lines running 3/8 in air piping; step up to size 400 or 600 or down to 200 depending on the flow your circuit needs - we confirm sizing against the published curves before you order. This unit carries the 5 um element (W) instead of the 40 um standard, the differential-pressure drain (the default, which bleeds the bowl as pressure differential builds), and a low-pressure-type regulator - note that the exact adjustment range for the low-pressure type is not published, so ask us to confirm it for your set pressure. The square gauge is fitted with a psi scale; MPa or bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the mounting bracket is included.
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 figure, so we do not quote one number. Tell us your inlet pressure and required downstream flow and we will confirm the correct size from the datasheet on request before you order.
The W in the code specifies the optional 5 um element instead of the 40 um standard, giving finer particulate and water removal ahead of the regulator and lubricator. The F2 specifies the embedded square gauge with a psi scale; MPa or bar scales are available as alternatives.
