The AirTAC GC300C10ALC2WK AirTAC F.R.L. Combination, 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 GC300C10ALC2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator working as one conditioning stack. This size 300 unit carries a PT3/8 (3/8 in) port, the 5 um filter element (code W) for finer water and particulate removal than the standard 40 um grade, an automatic drain that expels collected condensate without manual attention, and a low-pressure type regulator. A round pressure gauge scaled in psi is fitted, a reverse/check valve is built in, and the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The filter bowl on this size is polycarbonate.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and can be ordered with manual or differential-pressure draining, the 40 um standard element, square or round gauges in MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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.

Feeding clean, regulated and lubricated air to a CNC cell's pneumatic clamps, tool-change cylinders and chip-door actuators, with the 5 um element guarding fine pilot valves on the machine.
Conditioning the air feeding a packaging line's cylinder-driven carton closers and valve manifolds, where the regulator holds a steady low setpoint and the lubricator mists oil to the cylinders.
Supplying the air diverters, stoppers and pusher cylinders along a conveyor sortation system, with the automatic drain coping with condensate on a line that runs unattended across shifts.
Start with the size and port: 300 with a PT3/8 port suits lines running 3/8 in air drops; step up to 400 or 600, or down to 200, to match your pipe and demand. Choose the filter grade deliberately: the 40 um standard element protects most actuators and valves, while the 5 um element (this unit, code W) is the finer choice for delicate pilot valves and precision tools. Pick the drain to match access: automatic (this unit) where bowls are hard to reach, manual where an operator checks routinely, or differential-pressure as the default. Select the gauge style and scale - embedded square or external round, in MPa, psi or bar - and specify the thread you pipe in: PT is the standard, with G (BSPP) and NPT available as order options. The J code deletes the bracket if you do not want one.
One honest note before you order: AirTAC publishes flow as curves, not a single rated number, and the regulation range for this low-pressure (L) version is not stated in the material we hold. Tell us your line pressure and air demand and we will confirm the sizing and figures against the datasheet before you commit.
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 this family as curves rather than a single rated figure, so we do not quote a number. Send us your line pressure and air demand and we will confirm the sizing and the datasheet flow figures for this PT3/8 unit on request.
L marks the low-pressure type of regulator. The standard GC regulation range does not apply to this version, and the exact range for the low-pressure type is not published in the material we hold, so ask us to confirm it against the datasheet before ordering if your setpoint is critical.
