The AirTAC GC30015AF2WK AirTAC F.R.L. Unit 1/2 in PT, 5 um, Auto Drain 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015AF2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, pressure regulator and lubricator assembled as one air-preparation set. This configuration is built around 1/2 in PT ports in the GC300 size, with a 5 um filter element (the fine grade, in place of the standard 40 um), an automatic drain on the filter bowl, and a standard regulator covering 0.15-0.9 MPa (20-130 psi). The square gauge fitted to this unit reads in psi, a reverse/check valve is fitted, and the set includes a mounting bracket. The polycarbonate bowls suit the -5 to 70 C non-freezing operating range, with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge scale, thread (PT standard, with G and NPT as order options) and reverse valve. Flow is published 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.

A spray booth or finishing line drawing 1/2 in air drops benefits from clean, regulated, lubricated supply: the 5 um element removes water and fine particulate before atomising air reaches the guns, and the automatic drain keeps condensate off the floor without daily attention.
Carton formers, case sealers and wrap lines run many small cylinders and valves from one drop. A three-unit set at the machine inlet filters the plant air to 5 um, holds working pressure steady with the psi gauge in view of the operator, and carries oil mist to the actuators.
Fixture clamps, power chucks and tool-change cylinders on a machining centre need stable, conditioned air. The regulator holds clamp pressure within its 0.15-0.9 MPa range, the reverse/check valve helps hold the circuit on supply loss, and the bracket mounts the set at the machine frame.
Pick the size and port step against the air demand of the machine or line the unit feeds - the 300 size with 1/2 in PT ports sits in the middle of the range, and larger sizes carry larger ports and more flow. Choose the drain type for the filter bowl: automatic drain (fitted here) empties without attention, manual drain relies on an operator, and the differential-pressure default drains on a pressure drop. Choose the filter grade to match the downstream equipment: 5 um (this unit, code W) for finer protection, 40 um as the standard grade. Select the gauge scale (MPa, psi or bar) and whether you want the embedded square gauge or the optional external round gauge. Specify the thread - PT is the standard, with G (BSPP) and NPT as order options - and whether a bracket is required. Because flow is published as curves rather than a single rating, 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 the GC series as curves rather than a single rated figure, so there is no one rated flow number we can quote. Tell us your working pressure and air demand and we will confirm the flow and datasheet figures for this 300-size, 1/2 in unit on request.
The code W in GC30015AF2WK selects the optional 5 um element in place of the 40 um standard grade. The finer grade suits downstream equipment such as spray guns, precision valves and instruments; the 40 um grade remains available on other GC300 configurations if coarser general-purpose filtration is sufficient.
