The AirTAC GC400C15ALF2K AirTAC F.R.L. Unit PT1/2 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 GC400C15ALF2K is an AirTAC GC three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled to condition compressed air in one set. This size 400 unit is ported PT1/2, carries a 40 um filter element with an automatic drain on the filter bowl, and is built as the low-pressure regulator type with an embedded square gauge scaled in psi. A reverse/check valve is fitted and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature is -5 to 70 C (non-freezing), and the filter and lubricator bowls are polycarbonate at this size.
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 catalogue options include manual or differential-pressure drains, a 5 um filter element (code W), gauge scale in MPa, psi or bar, G (BSPP) or NPT threads, and bracket choices. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for this unit 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.

Mounted at the machine inlet, this three-unit set removes water and chips-laden particulate with the 40 um filter, holds a steady reduced pressure for clamps and tool-change cylinders, and feeds oil mist to the machine's air-operated components. The reverse/check valve holds the setting if the main supply dips.
Carton sealers, case packers and labeling heads run cylinder after cylinder all shift long. This size 400 unit at PT1/2 conditions the air feeding those actuators, with the automatic drain clearing condensate from the filter bowl without stopping the line.
On branch lines where a reduced, stable set pressure is required for air tools, clamps or blow-off stations, this low-pressure type regulator lets the workshop drop the line pressure at the point of use, while the filter and lubricator keep the downstream tools fed with clean, oiled air.
Start with size: the GC range steps from 200 to 600 as port size and flow demand grow, and this unit sits at size 400 with a PT1/2 port. Drain type is a real choice: automatic (as fitted here) discharges condensate without operator attention, while manual and differential-pressure drains suit installations where you prefer controlled or load-dependent dumping. Filter grade is 40 um standard; specify code W for 5 um where finer particulate protection is needed. Gauge scale can be MPa, psi or bar - this unit carries a square psi gauge. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the bracket can be omitted with code J. This is the low-pressure regulator type, so tell us your working pressure and we will confirm the adjustment range. Flow is published as curves, not a single rating, so ask us to check 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 rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for this size 400, PT1/2 unit on request.
The A in the code specifies an automatic drain on the filter bowl, which discharges collected condensate without operator attention. Manual and differential-pressure drains are catalogue alternatives on GC units if your installation suits them better - just ask and we will decode the right variant with you.
