The AirTAC GC400C15MLF2WK AirTAC F.R.L. 1/2 in PT, 5 um, psi gauge 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 GC400C15MLF2WK is a three-piece AirTAC F.R.L. combination: a filter, a regulator and a lubricator, each in its own body and assembled as one GC set. This configuration is built around a 1/2 in PT port on the GC400 size. The filter section carries the 5 um element (code W) with a manual drain and a polycarbonate bowl; the regulator is the low-pressure type and is fitted with the embedded square gauge scaled in psi plus a reverse/check valve (code K); the lubricator meters oil mist into the downstream air line. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC range is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, gauge scales in MPa, psi or bar, and G (BSPP) or NPT threads as order options alongside the PT standard. Flow for this unit is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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-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.

Spray guns and air-assisted applicators at a booth drop need air that is filtered to 5 um, held at a stable low setting and lightly oiled - this GC set provides all three functions at the point of use.
Cylinder-driven case erectors, sealers and labellers on a packaging line take their supply through this unit: water and particulate removed, pressure regulated and the cylinders fed with oil mist.
Fixture clamps, tool-changer cylinders and air chucks on a machining centre run dependably when the shop-air drop feeding them is filtered, regulated and lubricated by one GC400 set.
Size and port step up with air demand: GC400 with a 1/2 in PT port sits in the middle of the 200/300/400/600 range, so step up a size if your line draws more than the GC400 flow curve allows - we can check the curve against your consumption on request. The choices decoded into this code: manual drain (condensate is emptied by hand as part of a maintenance round; choose the automatic or differential-pressure drain codes if you cannot guarantee that routine), 5 um filtration instead of the 40 um standard where finer particulate removal matters, the low-pressure regulator type (its exact adjustment range is not published - confirm it with us), the square gauge scaled in psi, and the fitted reverse/check valve. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. 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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC400 as curves, not as a single rated figure, so we do not quote a number. Send us your line pressure and air consumption and we will confirm the flow curve and the datasheet figures for this exact unit on request.
The M in the code sets a manual drain: condensate collected in the filter bowl is emptied by hand as part of a maintenance routine. If nobody can guarantee that round, order the automatic (A) or differential-pressure (blank) drain code instead - both are catalogue options within the same GC400 family.
