The AirTAC GC30015F2WK 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 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015F2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator working together to clean, regulate and lubricate compressed air on one air-prep line. This size 300 configuration is built for 1/2 in PT ports and carries the W filter grade (5 um element, versus the standard 40 um), a differential-pressure drain on the filter bowl, a square pressure gauge reading in psi, a reverse/check valve on the regulator, and a mounting bracket. The filter and lubricator bowls are polycarbonate (PC); maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
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, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and G (BSPP) or NPT thread options alongside the standard PT. Flow is published in the AirTAC catalogue as curves rather than a single rated figure, so we confirm the datasheet and flow 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 spray guns and atomising valves on a finishing line: the 5 um element takes finer water and particulate out of the air, the regulator holds a steady set pressure, and the lubricator mists oil into the air supply for downstream air tools.
Supplying the cylinders and gripper actuators on a packaging or palletising conveyor: one F.R.L. point cleans the air, holds line pressure steady through machine cycles, and keeps lubrication consistent for the actuators working all shift.
Conditioning the shop-air feed to a CNC machining centre: the filter protects the machine's pneumatic circuits from water and chips of dirt in the incoming air, the regulator sets the supply pressure the machine expects, and the check valve holds the line against backflow.
Size 300 with a 1/2 in PT port suits lines where clean, regulated and lubricated air feeds a moderate-to-large air supply; step up to size 400 or 600, or down to 200, if your flow demand points elsewhere - we can check the published flow curves against your application before you order. The differential-pressure drain on this unit flushes condensate automatically as the pressure differential across the filter rises, with no daily manual draining; automatic or manual drains are available if you prefer. The 5 um (W) element is the finer of the two published grades (40 um standard) - choose it where downstream valves and cylinders need cleaner air. The square gauge is fitted here reading in psi; MPa or bar scales and an external round gauge are options. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a bracket is included. Ask us to confirm sizing against the 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 the GC series as curves in the catalogue, not as a single rated number, so there is no one figure we can quote honestly. Tell us your line pressure and the flow your equipment needs and we will confirm the sizing against the published curves and send the datasheet on request.
The W in the code GC30015F2WK selects the optional 5 um filtration grade; the GC standard element is 40 um. The finer 5 um element is the right choice when downstream valves, cylinders or air tools need cleaner air than the coarse grade provides. If your application is fine with coarse filtration, a standard-grade GC300 in the same size and port is available.
