The AirTAC GC30015AC2K AirTAC F.R.L. Combination Unit 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 GC30015AC2K is an AirTAC GC-series three-unit F.R.L. combination that treats compressed air in three stages: a filter removes water and particulate, a regulator holds downstream pressure steady, and a lubricator adds an oil mist for downstream air tools and cylinders. This 300-size unit is fitted with a PT1/2 (1/2 in) PT-threaded port, a 40 um standard filter element, an automatic drain that expels collected condensate without manual attention, and a round external gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a reverse/check valve is fitted to hold downstream pressure if the supply drops.
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 with options including manual or differential-pressure drains, a 5 um (W) filter element, gauge scale in MPa, psi or bar, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing 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: GF300-15 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 filtered, regulated and lubricated air to the clamping fixtures, tool-change actuators and air-powered spindle ancillaries on a CNC machining centre, with the 40 um element protecting valves from chips-laden, wet shop air.
Supplies treated air to the cylinders and grippers on a carton-forming and case-sealing conveyor line, where the automatic drain copes with condensate on a line that runs unattended across shifts.
Conditions the air at a paint or powder-coating booth drop, removing water and particulate before the regulator sets gun and pump pressure and the lubricator serves air-driven agitators and trigger valves.
Start with the size and port: 200, 300, 400 and 600 step up in both port size and flow capacity, so match the step to the air consumption of the machines downstream - this 300-size unit carries a PT1/2 port. Choose the drain to suit access: automatic (as here) suits units mounted where nobody regularly walks past, manual suits supervised points, and differential-pressure draining is the catalogue default. Filter grade is 40 um standard or 5 um (W) where finer particulate removal matters. Gauge scale can be ordered in MPa, psi or bar, and the thread can be PT (standard), G (BSPP) or NPT to match your piping. A bracket is included for mounting.
One honest note on sizing: AirTAC publishes flow as curves, not as a single rated number, so we cannot quote a rated flow figure here. Send us your application's air demand and we will confirm the correct size 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 the GC series as curves rather than a single rated figure, so there is no one rated flow number we can state. Tell us your application's air demand and working pressure and we will confirm the correct size and the flow figures from the datasheet on request.
In the code GC30015AC2K, the A sets an automatic drain, which expels collected condensate from the filter bowl on its own instead of relying on manual draining or a differential-pressure drop. The C2 sets the round external gauge with a psi scale; the embedded square gauge is the standard fitting and MPa, psi and bar scales are the catalogue options.
