The AirTAC AirTAC GC30015F2K 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015F2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 300-size set. This configuration is decodable from the model code itself: a PT1/2 (1/2 inch) PT-threaded port, standard 40 um filtration, a differential-pressure drain on the filter bowl, a standard regulator with a fitted square gauge scaled in psi, a reverse/check valve fitted, and a mounting bracket included. In use it filters water and particulate from the compressed air, holds a stable downstream pressure, and meters oil mist to downstream air tools and actuators - all from one mounting point.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including automatic or manual drains, a 5 um filter grade (code W), gauge scales in MPa, psi or bar, and G (BSPP) or NPT threads in place of the PT standard. Rated flow is published as curves rather than a single figure, so ask us to confirm flow and datasheet details 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 spray booths and air-assisted applicators on an automotive paint line, where filtered, regulated and lubricated air keeps spray guns and air motors behaving consistently through a shift.
Conditions the shop-air feed to a CNC machining centre's pneumatic circuits - tool-change cylinders, clamps and air blasts - with the regulator holding set pressure and the lubricator serving air-powered components.
Serves the valve-and-cylinder circuits of a carton-forming and case-sealing packaging line, where the filter's differential-pressure drain sheds condensate and the regulator stabilises pressure to the seal and transfer actuators.
Start with size and port: the 300 size with its 1/2 in PT port suits lines where the air demand sits above what a 200-size set comfortably serves - match the port step to your piping and let the required flow drive the size choice, and we will confirm the flow curve against your application. Then choose the drain: this unit carries the differential-pressure drain (the default), while automatic (code A) and manual (code M) versions exist if your maintenance routine prefers them. Filtration is the standard 40 um element; specify the W suffix for the 5 um grade if downstream equipment needs finer air. The fitted square gauge reads in psi; MPa and bar scales are available, and an external round gauge is optional. Threads can be ordered as G (BSPP) or NPT instead of the PT standard, and the reverse/check valve (code K) is already fitted here. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 this series as curves rather than a single rated figure, so we do not quote one number. Send us your operating pressure and air demand and we will confirm the flow from the datasheet curve and check the sizing against your application before you order.
The blank drain code on this model is the differential-pressure type, the standard arrangement for the GC series. If your maintenance routine suits it better, automatic (code A) and manual (code M) drain versions of the same set can be ordered - just tell us which you prefer and we will confirm the equivalent model.
