The AirTAC GC30015C2K 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30015C2K is a three-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one air-preparation set for compressed air. In this configuration the 1/2 in PT port suits a main drop or a large machine supply, the filter element is the standard 40 um grade with a differential-pressure drain on the bowl, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi). The bowls on the 300 size are polycarbonate (PC), a round external gauge reading in psi is fitted, a reverse/check valve is included, and the set comes with a mounting bracket.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of PT, G or NPT thread, manual or automatic drain options, a 5 um filter element (code W), gauge scale choices and a no-gauge variant. 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. 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.

Feeding a machine tool's pneumatic clamps, tool-change cylinders and air-blast nozzles from a 1/2 in main drop, with one set doing the filtering, pressure setting and mist lubrication in a single bracket-mounted station.
Supplying the cylinders and vacuum generators on a carton-forming and case-packing conveyor, where the filter sheds pipe-scale and water, the regulator holds a steady setting for consistent box sealing, and the lubricator mists the air for long cylinder life.
Mounting at the point of use on an assembly-cell air drop so impact wrenches, air ratchets and clamping fixtures each draw filtered, regulated and lubricated air, with the psi gauge letting technicians verify the set pressure at a glance.
Start with the size and port: the 300 size with a 1/2 in PT port sits in the middle of the GC range (200/300/400/600), so step up to 400 or 600 if your line needs more flow capacity, or down to 200 for compact drops - we can check the published flow curves against your demand before you order. For the drain, differential-pressure (this unit) dumps condensate automatically as the pressure drop across the element builds; choose automatic (code A) for unattended drains or manual (code M) where you want operator-controlled bleeding. The standard 40 um element protects most actuators and valves; specify the 5 um W grade when downstream equipment needs finer filtration. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are alternatives, and the N code deletes the gauge. PT is the standard thread here, with G (BSPP) and NPT available as order options, and the bracket is included for panel or wall mounting.
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, not as a single rated figure, so we do not quote a Cv, l/min or SCFM number. Send us your application details and we will confirm the flow and sizing figures from the datasheet on request before you order.
The K means a reverse/check valve is fitted, which holds the downstream circuit against backflow. A GC set gives you three separate pieces - filter, regulator and lubricator - so each can be positioned and serviced independently, while a GFC two-unit set combines the filter and regulator in one body and suits tighter panels. This unit also carries the round psi gauge (C2), the standard 40 um element, a differential-pressure drain and a mounting bracket.
