The AirTAC GC30015ALC2 AirTAC F.R.L. Combination 1/2 in PT 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 GC30015ALC2 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply unit. This configuration is the 300 size with PT1/2 (1/2 in) PT ports, a 40 um filter element with an automatic drain that ejects collected condensate without manual attention, a low-pressure regulator fitted with a round gauge scaled in psi, and mounting brackets included. The filter and lubricator bowls on this 300 size are polycarbonate (PC), and the unit handles compressed air at up to 1.0 MPa (145 psi) inlet with an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is available in 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge style and scale, and G (BSPP) or NPT threads in place of the PT standard. Flow is published in the catalogue 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.

Feeds spray-booth and paint-gun air drops on an automotive assembly line, where filtered, regulated and lubricated air keeps atomising air steady and gun internals coated in a fine oil mist.
Serves the pneumatic cylinders on a carton-forming and sealing conveyor line, giving one point at the line drop where water, particulate, pressure setting and lubrication are all handled.
Prepares shop air ahead of clamps, air chucks and tool-change actuators on CNC machining centres, protecting downstream valves and cylinders from condensate and unregulated supply pressure.
Start with the size and port: the 300 size with PT1/2 ports suits lines running 1/2 in air supply, while the 200/400/600 steps cover smaller or larger ports and flow demands - match the step to the flow your circuit needs. Choose the drain to suit access: automatic (as fitted here) empties the bowl unattended, manual suits attended stations, and differential-pressure drain is the catalogue default. Filter grade is 40 um standard; specify the W option for 5 um where finer particulate removal matters. The regulator here is the low-pressure type with a round psi gauge; embedded square gauges and MPa/bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT available to order; brackets are included with this unit.
One honest note before ordering: AirTAC publishes flow for this family as curves, not as a single rated number, so send us your flow and pressure requirements and we will confirm the right size 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 GR300-15 regulator with a GF300-15 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. Send us your required flow and working pressure and we will confirm the sizing from the datasheet on request before you order.
The A in the code GC30015ALC2 selects the automatic drain, which ejects condensate from the filter bowl without manual attention - useful where the unit sits in an inaccessible spot or on an unattended line. The L selects the low-pressure regulator type; its exact adjustment range is not published in the material we hold, so confirm the set pressure you need with us and we will verify it against the datasheet.
