The AirTAC GC400C15ALF2W 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 GC400C15ALF2W is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled for 1/2 in PT ports. This configuration carries an automatic drain on the filter bowl, a 5 um filter element (the finer of the two catalogue grades), a low-pressure type regulator and an embedded square gauge scaled in psi. The bowl is metal and the set includes a mounting bracket.
It is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in, a choice of drain types, 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application.

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.

Filter, regulate and lubricate the air feeding spray guns and actuated cylinders on a paint-shop line; the 5 um element and automatic drain keep water and particulate away from the finish.
Supply filtered, regulated and lubricated air to the cylinders and air motors along a packaging conveyor, with the square psi gauge giving operators a local setpoint reading at the machine.
Prepare air for clamps, fixtures and small pneumatic presses in a machining cell, with the lubricator metering oil mist to downstream cylinders while the automatic drain clears condensate.
Size and port are the first decision: 400 is the third of four frame sizes (200/300/400/600) and this unit is drilled for 1/2 in PT, so match the frame to the air demand of your line - we can check the published flow curves against your requirement before you order. The remaining choices are all decodable from the code: drain type (automatic here; differential-pressure and manual are also offered), filter grade (5 um here, 40 um standard), gauge (square, psi scale here; an external round gauge and MPa or bar scales are options), thread (PT standard; G and NPT are order options) and the low-pressure regulator type. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering.
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 number here. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The W in the code selects the 5 um element; 40 um is the standard grade. Both are catalogue options on the GC filter stage and the automatic drain works with either. If your application tolerates coarser filtration, ask us to quote the 40 um variant.
