The AirTAC GC30015ALC2GK AirTAC F.R.L. Combination G1/2 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 GC30015ALC2GK is a three-piece AirTAC GC-series F.R.L. combination: a filter, a pressure regulator and an oil-mist lubricator assembled as one air-preparation set. This size 300 unit is ported G1/2 (BSPP) as coded - PT is the catalogue standard thread, with G and NPT as order options. The filter section carries the standard 40 um element with an automatic drain, the regulator is the low-pressure type, an external round gauge scaled in psi is fitted, and a reverse/check valve and mounting bracket are included. The filter and lubricator bowls are polycarbonate at this size.
This is a genuine AirTAC part. The GC range is available in sizes 200, 300, 400 and 600, with a choice of drain type (differential-pressure, automatic or manual), 40 um or 5 um (W) filtration, gauge scale in MPa, psi or bar, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working 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 the datasheet and sizing for your application.

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.

Filter, regulate and lubricate the shop-air feed to a CNC cell's pneumatic clamps, tool-change cylinders and blow-off nozzles from a single G1/2 drop.
Condition the air feeding stopper cylinders, diverters and gate actuators along a bottling conveyor, with the automatic drain handling condensate at the drop.
Supply regulated, oil-mist lubricated air to impact wrenches and nutrunners at a vehicle assembly station, with the check valve blocking backflow through the set.
Size 300 with G1/2 ports sits mid-range in the GC line; step up to 400/600 or down to 200 depending on the air demand of your circuit - we can check the published flow curves against your requirement before you order. Drain type matters: automatic empties the filter bowl without attention, manual relies on a routine drain, and the differential-pressure default suits steady duty. Filtration here is the 40 um standard element; specify W for a 5 um grade. The fitted round gauge reads in psi; the embedded square gauge is the standard alternative, with MPa or bar scales orderable. Thread on this code is G (BSPP); PT is the standard and NPT is orderable. Mounting bracket is included. Note the regulator is the low-pressure type (L); its exact adjustment range is not published, so confirm it with us 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 GR300-15 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 there is no one rated-flow number we can quote. Send us your line pressure and air demand and we will confirm the sizing from the datasheet before you order.
L marks the low-pressure regulator type, intended for circuits running below standard line pressure; its exact adjustment range is not published, so confirm it with us. C2 means an external round gauge scaled in psi is fitted - the embedded square gauge is the standard alternative, with MPa or bar scales orderable.
