The AirTAC GC300C10ALC2 AirTAC F.R.L. Combination PT3/8 Low-Pressure 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 GC300C10ALC2 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator working together to clean, regulate and lubricate compressed air on one supply line. This size 300 unit is configured with a 3/8 in PT port, automatic drain on the filter bowl so collected condensate is discharged without manual attention, a 40 um standard filter element, a low-pressure type regulator, and a fitted round gauge scaled in psi. A mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including manual or differential-pressure drains, a 5 um filter element (code W), gauge scale in MPa, psi or bar, and G (BSPP) or NPT threads in place of the PT standard. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet figures 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.

Feeding cleaned, lubricated and pressure-regulated air to clamping cylinders and light-duty pneumatic presses on a fabrication line, where the low-pressure type regulator holds a moderate working pressure for the tooling.
Conditioning the air supply to packaging machinery actuators and grippers, with the automatic drain handling condensate on a line that runs unattended through shifts and the lubricator misting downstream cylinders.
Serving as the point-of-use F.R.L. at an assembly bench air drop, filtering water and particulate from the shop supply, regulating it to the bench working pressure on the psi gauge, and lubricating air tools connected downstream.
Start with size and port: the GC series steps through sizes 200, 300, 400 and 600, and the port on this unit is 3/8 in PT - pick the size whose flow curve covers your demand rather than matching port thread alone. This unit has the automatic drain, which suits unattended or hard-to-reach installations; manual and differential-pressure drains are available if you prefer operator-controlled or pressure-differential discharge. The 40 um element is the standard grade; specify the 5 um option (code W) where finer particulate removal is needed. The fitted round gauge reads in psi; MPa and bar scales are alternatives, and an embedded square gauge is the standard style. Thread is PT as standard - G (BSPP) and NPT are order options. Note that this is the low-pressure type regulator, so confirm the adjustment range suits your set pressure before ordering. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application.
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, not as a single rated figure, so we do not quote a rated flow number. Send us your application details - required flow, working pressure and port size - and we will confirm the correct size from the datasheet curves before you order.
The L in the code marks the low-pressure type regulator, intended for applications where the set pressure is below what the standard type covers; the exact adjustment range for this configuration is not published in the material we hold, so we confirm it on request. The A marks the automatic drain on the filter bowl, which discharges collected condensate by itself instead of requiring manual draining.
