The AirTAC GC400C15ALF2G AirTAC F.R.L. Combination, G1/2, Low-Pressure 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 GC400C15ALF2G is an AirTAC GC three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one set. This configuration is size 400 with G1/2 (G/BSPP thread) ports, an automatic drain on the filter bowl, the standard 40 um filter element, a low-pressure regulator type, and an embedded square gauge reading in psi. It conditions compressed air in one pass - removing water and particulate, holding a set downstream pressure, and adding oil mist for air tools and cylinders. Maximum working (inlet) pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC line comes in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options that include manual or differential-pressure drains, a 5 um (W) filter element, MPa or bar gauge scales, an external round gauge, a reverse/check valve, and PT or NPT threads in place of G. Flow for this series 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.

Filtered, regulated and lubricated air to spray guns and air motors on a paint line, where the low-pressure regulator holds a gentle setpoint and the 40 um element keeps water and grit out of the finish.
Supplying clamps, air chucks and tool-change cylinders on a machining centre, with the lubricator feeding oil mist downstream and the psi gauge giving operators a visible setpoint at the machine.
Running diverters, pushers and conveyor-mounted cylinders on a packaging line, where the automatic drain clears condensate and the set keeps every actuator fed with clean, regulated, lubricated air.
The real choices on this series are decodable from the code. Step the size (200/300/400/600) and port to match the flow your line needs - this unit is size 400 with 1/2 in ports. On the filter you pick the drain: automatic (as here), manual, or differential-pressure, and the element grade: 40 um standard or 5 um (W) for finer filtration. On the regulator you choose standard or low-pressure (L) type, and the gauge: embedded square as standard with MPa, psi or bar scales, or an optional external round gauge. Threads come as PT (the standard), G or NPT; a mounting bracket is included on this set. One honest note: flow is published as curves, not a single rating, so send us your application 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 this series as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your application and required flow, and we will confirm the sizing from the datasheet on request before you order.
The trailing G means G (BSPP) parallel thread on the 1/2 in ports. PT is the standard thread for this series, and G and NPT are catalogue options selected by code - this unit is simply built with the G option. Thread choice is a specification, not a delivery promise.
