The AirTAC GC30015ALC2K AirTAC F.R.L. Combination, PT1/2 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 PT1/2" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015ALC2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 300-size unit for 1/2 in PT ports. The filter section removes water and particulate down to the standard 40 um grade, with an automatic drain that expels collected condensate from the PC (polycarbonate) bowl without manual attention. The regulator is the low-pressure type, fitted with an external round gauge reading in psi, and a reverse/check valve is fitted. 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 200, 300, 400 and 600 sizes with a choice of ports, drain types, filter grades, gauge styles and scales, and G or NPT thread options to order. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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: GF300-15 filter, GR300-15 regulator and GL300-15 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.

Conditions the compressed air feeding a machine tool's pneumatic clamps and tool-change cylinders: filtered, held at a stable low working pressure, and carrying a fine oil mist to keep actuator seals and valves lubricated through long production runs.
Serves the air cylinders on a carton-forming and taping conveyor, where the automatic drain keeps condensate out of the supply during continuous shifts and the lubricator extends the life of the sealing and pusher cylinders.
Mounted as a point-of-use station on a plant air drop serving impact wrenches, grinders and air ratchets, giving maintenance crews one connection point that filters the supply, sets the low working pressure the tools need, and mists oil into the air stream.
Start with the port and size: this unit is 300 size with a 1/2 in PT port; step up or down the 200/300/400/600 range if your line needs a different connection or flow capacity. The automatic drain suits unattended duty; choose manual or differential-pressure drain variants if you prefer operator-controlled or load-proportional condensate removal. The 40 um grade is the standard element; a 5 um element (code W) is available where finer filtration is needed. The round psi gauge is fitted here; embedded square gauges and MPa or bar scales are the other catalogue choices. PT is the standard thread, with G (BSPP) and NPT available as order options, and a mounting bracket is included. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing against the datasheet 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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC publishes flow for this series as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and the air demand of your equipment and we will confirm the flow and sizing from the datasheet on request before you order.
This unit carries the L (low-pressure) regulator variant, intended for applications whose working pressure sits below the standard regulator's range; the exact adjustment range for this variant is not published in our sheet, so we will confirm it on request. The fitted round gauge reads in psi, and MPa or bar scales and an embedded square gauge are the other catalogue options.
