The AirTAC GC30015C2GK 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015C2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one filter-regulate-lubricate package for compressed-air lines. This unit is built in the 300 size with a 1/2 in port in G (BSPP) thread. The filter element is the standard 40 um grade, the bowl drains by differential pressure, and the bowls on this size are polycarbonate (PC). Regulation is the standard type with a 0.15-0.9 MPa (20-130 psi) adjust range, a round external gauge with psi scale is fitted, a reverse/check valve is included, and a mounting bracket comes with the unit.
This is a genuine AirTAC part. The GC family is available in 200, 300, 400 and 600 sizes, with port and thread options, 40 um or 5 um (W) filtration, differential-pressure, automatic or manual drains, gauge style and scale choices, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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 spray guns and air-assisted equipment on a paint line, where clean, moisture-managed and consistently pressurised air keeps finish quality stable across shifts.
Prepares the air feeding cylinders and air-driven grippers on a bottling or carton-packing conveyor, so valve actuators receive lubricated air at a set pressure while condensate and particles are drained off upstream.
Conditions the shop-air feed to a CNC machining centre's pneumatic tool-changer and clamping circuits, combining particle filtration, a fixed regulated pressure and oil-mist lubrication in one mounted unit.
Choose the GC size by the port and flow step your line needs: 200, 300, 400 or 600, each stepping up in port size and capacity. On this 300 unit the 1/2 in G-threaded port suits mid-size supply runs; PT is the standard thread and G or NPT are order options. Pick the drain to match the installation: differential-pressure (as fitted here) drains automatically while the unit flows, automatic (A) drains on a timer-free cycle, and manual (M) needs someone to open the bowl. Choose 40 um for general air preparation or the 5 um (W) element where finer particle removal matters. Gauge style is embedded square by default with an external round gauge optional, in MPa, psi or bar scales; this unit carries the round psi gauge. A reverse/check valve (K) holds downstream settings if upstream pressure collapses, and a bracket simplifies panel mounting.
Flow for the GC series is published as curves, not a single rated number, so we cannot quote one honestly here. Send us your application details and we will confirm the sizing against the datasheet curves 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 we do not quote one. Tell us your line pressure and the air demand of your equipment, and we will confirm the sizing against the datasheet curves on request before you order.
The C2 code on GC30015C2GK specifies an external round gauge with a psi scale; the embedded square gauge is the standard alternative, with MPa, psi or bar scales available. The K code means a reverse/check valve is fitted, which holds the downstream setting if upstream supply pressure collapses. Both are decodable choices you can specify differently on other units in the range.
