The AirTAC GC400C15AF2G AirTAC F.R.L. Combination, G1/2, 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400C15AF2G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one coordinated set. This 400-size unit is built with a G1/2 (BSPP) port, 40 um standard filtration, an automatic drain on the filter bowl, and a fitted square gauge reading in psi. The standard regulator covers a setting range of 0.15-0.9 MPa (20-130 psi), the polycarbonate bowls suit the -5 to 70 C non-freezing operating range, and a mounting bracket is included for panel or wall fixing.
This is a genuine AirTAC part. The GC line is published in 200, 300, 400 and 600 sizes with a choice of PT, G or NPT threads, differential-pressure, automatic or manual drains, a 5 um (W) filter element option, gauge scale choices and reverse/check valve options. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application before you order.

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-C1 filter, GR400-C1 regulator and GL400-C1 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 clean, regulated and lubricated air to the clamping cylinders, tool-change actuators and air blow-off circuits of a CNC machining centre, with the automatic drain handling condensate from a humid compressor room.
Conditioning the air feeding carton-forming and case-sealing cylinders on a packaging line, where the regulator holds a steady setting for consistent seal stroke speed and the lubricator keeps the cylinder seals running smoothly.
Supplying spray guns and air-assisted applicators in a finishing booth, where 40 um particulate removal, a stable regulated pressure and light oil misting protect finish quality and gun life.
Start with the port step: this unit is 400 size with a G1/2 port, one step up from 300 (1/2 in vs 3/8 in), and one step below 600 (1 in). Match the size to the air demand of the downstream circuit; if your consumption sits between two sizes, ask us to check the flow curves against your application before ordering. Drain choice matters: this configuration has an automatic drain, which expels collected condensate without daily attention, while manual and differential-pressure drains are available elsewhere in the series. Filtration is 40 um standard; specify the W code for 5 um where finer protection is needed. The fitted square gauge reads psi; MPa and bar scales are alternatives. This unit carries a G (BSPP) thread; PT is the standard thread for the series and G or NPT are orderable options. A mounting bracket is included.
Because rated flow for the GC series is published only as curves, not as a single number, we do not quote a flow figure here. Send us your air consumption and line pressure and we will confirm sizing 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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote a flow number on this page. Send us your application details and we will confirm the relevant flow and sizing figures from the datasheet on request.
This configuration carries the A code, meaning the filter bowl drains condensate automatically without operator attention. The GC series is also available with a manual drain or the differential-pressure (blank code) drain; if your maintenance routine suits a different drain type, ask us for the matching model code.
