The AirTAC GC30015F2WGK AirTAC F.R.L. Combination, G1/2, 5 um 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 GC30015F2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one complete air-treatment set. This configuration is built for 1/2 in ports with G (BSPP) threads, carries the W fine-filtration element rated at 5 um, and drains condensate by the differential-pressure method. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, a square gauge graduated in psi is fitted, and a reverse/check valve is included so downstream pressure is held if the supply line is lost. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The filter and lubricator bowls on this size are PC (polycarbonate).
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600 with a choice of ports and threads, drain types, 40 um or 5 um filtration, gauge style and scale, and with or without a reverse/check valve. Flow is published in the catalogue 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.

A 5 um element ahead of spray guns and air-assisted applicators keeps water and fine particulate out of the finish, while the lubricator mists oil to the air motors and the regulator holds a steady gun pressure on a 1/2 in drop.
Feeding clamps, grippers and small pneumatic presses on an automation cell: the regulator holds set clamping pressure, the reverse/check valve holds it if the main supply drops, and the 5 um element protects the directional valves.
A complete F.R.L. set at the header of a packaging or palletising line, conditioning the air feeding conveyor diverters, case erectors and cylinder-driven sealers, with the lubricator keeping cylinder seals and valve spools oiled.
Sizing starts with the port step: this unit is the 300 size with 1/2 in ports, so match it against the flow your line actually needs - the catalogue publishes flow as curves, not one rated number, so send us your demand and we will confirm the right size. Filtration here is the 5 um (W) element; choose it when downstream valves and cylinders need finer protection than the 40 um standard element provides. The differential-pressure drain flushes condensate automatically as the pressure differential across the element builds, with no operator attention; if you prefer a timed or fully automatic drain, other GC configurations cover those options.
The fitted square gauge reads in psi, with MPa and bar scales available on other variants, and an external round gauge is an option if you prefer panel-side visibility. Threads are G (BSPP) on this code; PT is the standard thread and NPT is also a catalogue option. A mounting bracket is included, and the reverse/check valve (K) holds the regulated downstream pressure on air failure.
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 number. Tell us your line pressure and the air demand of the equipment you are feeding, and we will confirm the sizing against the datasheet curves for this 300-size, 1/2 in unit before you order.
The W in the code specifies the 5 um element instead of the 40 um standard, giving finer protection for downstream valves, cylinders and tools. The K specifies a reverse/check valve, which holds the regulated downstream pressure if the upstream supply is interrupted. Both are decodable choices on the GC series, and the gauge fitted here is the embedded square type reading in psi.
