The AirTAC GC400C15MLF2W AirTAC F.R.L. Combination PT1/2 5 um 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 AirTAC GC400C15MLF2W is a three-piece F.R.L. combination: a filter, a pressure regulator and an oil-mist lubricator assembled as one GC400 unit for 1/2 in (PT1/2) piping. The filter stage carries the 5 um element (code W) with a manual drain, so the bowl is drained by an operator during routine checks rather than automatically. The regulator is the low-pressure type, fitted with an embedded square gauge reading in psi, and no reverse/check valve is fitted. The bowls are metal, a mounting bracket is included, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options for thread (PT standard; G and NPT to order), drain type, filter grade and gauge scale. Flow for this combination is published as performance 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-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.

Feeds clean, regulated and lubricated air to clamps, tool changers and air-powered fixtures on a machining centre, with the 5 um element helping protect fine-seal components.
Supplies spray guns and air-assisted applicators on a paint line, where the low-pressure regulator holds a gentle setting and the lubricator carries oil mist to the gun.
Runs the cylinders and air actuators on a packaging conveyor's box-forming and sealing stations, with manual-drain bowls suited to a line checked every shift.
Step through sizes 200, 300, 400 and 600 to match the port and the flow your line needs; this 400 unit is piped at PT1/2, with G or NPT threads available as order options. Choose the drain: manual (as here) for attended maintenance, automatic for unattended draining, or the default differential-pressure type. Pick the filter grade: 40 um standard or 5 um (W) for finer protection - this unit carries the 5 um element. Gauge scales are MPa, psi or bar; this one reads psi on the embedded square gauge, with an external round gauge optional. Because flow is published as curves rather than one rated number, send us your air demand and we will confirm sizing against 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 performance curves, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the flow from the datasheet for this exact configuration on request.
The M in the code selects a manual drain: an operator opens the drain on the filter bowl during routine checks instead of relying on the default differential-pressure drain or the automatic option. It suits lines that are attended regularly; if the unit runs unattended, ask us about the automatic-drain variant.
