The AirTAC GC40015AC2K 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 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015AC2K is an AirTAC GC400 three-unit F.R.L. combination: a separate filter, pressure regulator and lubricator assembled as one air-preparation set. This configuration has 1/2 in PT ports, a 40 um standard filter element with an automatic drain on the filter bowl, and a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi). A round gauge with a psi scale is fitted so the set pressure can be read directly, and a reverse/check valve is included to hold downstream pressure if the supply is interrupted. 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 are polycarbonate (PC); only the 600 size uses aluminium alloy bowls.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, G (BSPP) or NPT threads as order options, automatic, manual or differential-pressure drains, a 5 um (W) filter element option, and gauge scale choices of MPa, psi or bar. Flow is published by AirTAC as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeds spray guns and pneumatic applicators on a paint line, where the filter removes water and particulate, the regulator holds a steady gun pressure, and the lubricator mists oil to the air motors downstream.
Supplies the cylinders and grippers on a carton-forming and sealing conveyor, giving the machine one point where air is cleaned, set to a fixed pressure and lubricated for long cylinder life.
Prepares the air feeding a bench-mounted pneumatic press or clamping fixture, with the regulator setting clamping force, the 40 um filter protecting the valve, and the check valve holding pressure if supply drops.
Start with the port size: this unit is the 400 size with 1/2 in PT ports, one step above the 300 size for higher air demand. Match the size step to the flow your circuit needs rather than to the pipe alone, because flow for the GC series is published as curves, not a single rating - we will confirm the curve figure for your operating conditions on request before you order. The drain on this unit is automatic, so condensate is expelled without manual intervention; manual and differential-pressure drains are the other catalogue choices. The 40 um element is the standard grade, with a 5 um (W) element available where finer particulate removal is needed. The fitted round gauge reads in psi; MPa and bar scales are the alternatives, and an embedded square gauge is the standard gauge style. PT thread is the standard here, with G (BSPP) and NPT available as order options. A mounting bracket is included with this configuration.
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 number, so we do not quote a flow figure here. Send us your line pressure and air demand and we will confirm the flow from the datasheet for this 400 size, 1/2 in port unit on request before you order.
The A in the code GC40015AC2K means the filter bowl drains automatically, so collected condensate is expelled without anyone opening the drain. The catalogue alternatives are a manual drain (code M) and a differential-pressure drain (blank), which is the default. The same drain-choice logic applies across the GF, GFR, GFC and GC families.
