The AirTAC GC40015AF2GK AirTAC F.R.L. Combination, G1/2 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 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC40015AF2GK is a three-unit F.R.L. combination that filters, regulates and lubricates compressed air in one assembly: a separate filter with drain bowl, a pressure regulator and an oil-mist lubricator. This size 400 unit is specified with a G1/2 port (G thread), a 40 um filter element and an automatic drain that expels collected condensate without manual attention. The fitted square gauge reads in psi, the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and a reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and the filter bowl is polycarbonate (PC).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with matching ports, and can be ordered with a 5 um filter element (code W), manual or differential-pressure drain, alternative gauge scales (MPa, psi or bar), and PT, G or NPT thread. A mounting bracket is included with this unit. Flow is published as curves rather than a single rated figure, so contact us and we will confirm the datasheet 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: GF400-15 filter, GR400-15 regulator and GL400-15 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 filtered, regulated and lubricated air to the clamping, tool-change and spindle-aux circuits of a CNC machining centre, with the check valve holding downstream settings if upstream pressure dips.
Supplying treated air to the cylinders and actuators on a carton-forming and case-sealing conveyor line, where the automatic drain keeps condensate out of valves during continuous shifts.
Conditioning air at the drop to pneumatic tools and spray equipment in an automotive body shop, removing water and particulate at 40 um and delivering oil mist for tool lubrication.
Start with the size and port: GC units step through sizes 200, 300, 400 and 600, each with a larger port and higher flow capability, so match the step to the air demand of the machine or line being supplied. This unit is already fixed at size 400 with a G1/2 port and G thread; PT is the standard thread and G/NPT are order options if your piping needs them. Drain type is a real choice: automatic (as fitted here) suits unattended duty, while manual and differential-pressure drains are available. Filter grade is 40 um standard, with 5 um (code W) where finer particulate removal is needed. The gauge is the embedded square type reading psi; external round gauges and MPa or bar scales are optional.
One honest note before ordering: flow is published as curves, not a single rated number, so we cannot quote a rated flow figure here. Ask us to confirm sizing against your application from the datasheet before you order.
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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not state a rated flow, Cv or SCFM number here. Send us your application details and we will confirm the relevant flow figures from the datasheet on request before you order.
The A in the code GC40015AF2GK means the filter bowl has an automatic drain, which expels collected condensate on its own and suits unattended or continuous-duty installations. GC units can also be ordered with a manual drain or the differential-pressure drain (the default when no drain code is given).
