The AirTAC GC40015AC2GK AirTAC F.R.L. G1/2 Three-Unit Combination 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 GC40015AC2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 400-size unit with G1/2 (BSPP) ports. It cleans compressed air of water and particulate down to the standard 40 um grade, regulates downstream pressure within the 0.15-0.9 MPa (20-130 psi) adjustment range, and adds oil mist for air tools and cylinders. This configuration has an automatic drain on the filter bowl, a round external gauge with a psi scale, and a reverse/check valve fitted. The polycarbonate bowls suit the -5 to 70 C (non-freezing) operating range, and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GC line is offered in 200, 300, 400 and 600 sizes with a choice of PT, G or NPT threads, manual, automatic or differential-pressure drains, a 5 um (code W) filter element option, gauge scale in MPa, psi or bar, and bracket options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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 cleaned, regulated and lubricated air to tool-clamp and pallet-change cylinders on a machining centre, with the automatic drain handling condensate from a busy shop-air drop.
Conditioning the air feeding pneumatic press and clamping stations on an assembly line, where the regulator holds set pressure and the lubricator keeps cylinders and valves running smoothly.
Supplying treated air to impact wrenches, tyre chucks and lift tables in a commercial-vehicle workshop, with the round psi gauge letting technicians set and verify working pressure at the drop.
Size 400 with G1/2 ports sits in the upper-middle of the GC range; step up to 600 or down to 300 depending on the flow your line needs - we can check the published flow curves against your demand if you send the figures. This unit ships as a three-piece set (filter + regulator + lubricator) rather than the two-piece GFC; choose GC when you want oil mist supplied downstream of regulation. The automatic drain here empties the filter bowl without manual attention; manual and differential-pressure drains are alternative codes. The 40 um element is standard - specify the W code for 5 um where finer filtration is needed. The fitted round gauge reads psi; square embedded gauges and MPa or bar scales are other options. Thread is G (BSPP); PT and NPT are order options, and a mounting bracket is included.
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 rather than a single rated number, so we do not quote a rated flow, Cv or SCFM figure. Send us your line pressure and air demand and we will confirm the sizing from the datasheet curves on request before you order.
This GC40015AC2GK combines a separate filter, regulator and lubricator, so it adds oil mist for tools and cylinders where a GFC's filter-regulator alone would not. The automatic drain code (A) means the filter bowl ejects collected condensate on its own, with no manual draining; manual and differential-pressure drain versions are available as other codes.
