The AirTAC GC300C10ALC2WG AirTAC F.R.L. Combination, G3/8 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator built up as one working set. This GC300C10ALC2WG is the 300 size with a G3/8 (G/BSPP) port. The filter carries a 5 um element with an automatic drain, so collected water is ejected without manual intervention, and the 300-size bowls are polycarbonate (PC). The regulator is the low-pressure type, fitted here with an external round gauge scaled in psi, and the lubricator meters oil mist into the downstream air. Max inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), a mounting bracket is included, and no reverse (check) valve is fitted.
This is a genuine AirTAC part. The GC range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, offered with a choice of drain type, 40 um or 5 um filtration, gauge style and scale (MPa, psi or bar), and PT, G or NPT thread. Flow is published as curves rather than a single rating, so ask us to confirm sizing and the full datasheet 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-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.

Supplying clean, regulated and lubricated air to pneumatic clamps and tool-change cylinders on a machining centre, with the 5 um element and automatic drain protecting downstream valves from water and fine particles.
Feeding the pick-and-place cylinders and gating actuators along a bottling conveyor, where the lubricator keeps seals moving smoothly and the low-pressure regulator holds a gentle, consistent setting.
Feeding impact wrenches and air ratchets at vehicle assembly bays, where the low-pressure regulator protects the tools and the oil-mist lubrication extends vane and seal life.
Step through the GC sizes (200/300/400/600) to match the port and the flow your line needs; this unit is the 300 size on a G3/8 G-thread port. Drain type: automatic here, so the filter bowl discharges condensate unattended; manual and the default differential-pressure drain are the alternatives. Filter grade is 5 um on this unit (code W) against the 40 um standard. The regulator is the low-pressure type; its set range is not published, so confirm it with us. Gauge is the external round type scaled in psi; the embedded square gauge and MPa/bar scales are the other options. Thread is G; PT is the standard and NPT is an order option. Bracket included. Flow is published as curves, not a single rating - ask us to confirm sizing against your application before ordering.
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 a number here. Tell us your application and we will confirm the flow and the full datasheet figures for this exact model on request.
The W in the code specifies the 5 um element; the GC series standard is 40 um. Choose 5 um where downstream valves, cylinders or instruments need finer protection, or order the standard grade where coarse water and particle removal is enough. This unit also has an automatic drain, so the filter bowl discharges condensate without manual draining.
