The AirTAC GC40010AF2WK AirTAC F.R.L. Combination, PT3/8 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 PT3/8" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40010AF2WK is an AirTAC GC series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is the 400 size with a PT3/8 port, fitted with a 5 um filter element (the finer of the two catalogue grades), an automatic drain on the filter bowl, a standard regulator with an embedded square gauge scaled in psi, and a reverse/check valve. It cleans water and particulate from the compressed air, holds a set downstream pressure, and adds oil mist for air tools and cylinders in one mounting.
This is a genuine AirTAC part. The GC series is available in 200, 300, 400 and 600 sizes with a choice of PT, G or NPT thread, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge scale options, and with or without a reverse/check valve. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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: GF400-10 filter, GR400-10 regulator and GL400-10 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 pneumatic press or clamping fixture: the 5 um element protects the valve stack from water and swarf, the regulator holds a stable working pressure for repeatable forming, and the lubricator mists oil to the cylinder seals.
Supplying air to diverters, lifters and sealing cylinders on a packaging conveyor: clean, regulated and lubricated air at one point keeps the whole line's actuators running without per-machine treatment.
Conditioning air ahead of spray guns in a paint or coating booth: the 5 um grade removes water and particulate that would spoil finish quality, while the regulator sets gun pressure and the lubricator is set to suit the tooling.
Start with the port size: the 400 size carries PT3/8 here, while 200, 300 and 600 sizes step down or up in port and flow capacity, so match the size to the air demand of the downstream circuit. Choose the drain type: automatic drain (as fitted here) empties the bowl without attention, manual drain relies on an operator, and the differential-pressure default drains on a pressure drop. Choose the filter grade: 40 um is the standard element and 5 um (code W, fitted here) suits finer protection. Select the gauge scale (MPa, psi or bar) and whether a reverse/check valve is wanted; PT is the standard thread, with G and NPT available as order options.
Because flow is published as curves rather than one rated figure, 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 GR400-10 regulator with a GF400-10 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 working pressure and air demand and we will confirm sizing from the datasheet on request.
This unit carries code A, the automatic drain, so the filter bowl ejects collected condensate without an operator opening it - useful on lines that run unattended. Manual drain (code M) is the lower-cost choice where someone checks the bowls routinely, and differential-pressure drain is the catalogue default.
