The AirTAC GC400-15LC2K AirTAC F.R.L. Combination, 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 PT1/2" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400-15LC2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 400-size set with a 1/2 in PT port. The filter section removes water and particulate down to 40 um (the standard grade), the differential-pressure drain bleeds collected condensate automatically as flow varies, and the lubricator meters oil mist into the downstream air. The regulator is the low-pressure type, and this configuration carries a round external gauge scaled in psi plus a reverse/check valve fitted. Maximum working (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 line is offered in 200/300/400/600 sizes with port options from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, and gauge or no-gauge variants. The 400-size bowls are polycarbonate; only size 600 uses aluminium alloy. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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: GF400-15 filter, GR400-15 regulator and GL400-15 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 spray guns and air-assisted applicators on a finishing line: filtered, regulated and lubricated air in one set keeps atomising air clean and consistently conditioned across a shift.
Supplies the cylinders and air grippers on carton formers, case packers and sealing heads, where the low-pressure regulator band and oil-mist lubrication suit long-running actuator duty.
Installed at the point of use on a workshop air drop serving impact drivers, clamps and small presses, combining water and 40 um particulate removal with regulation and lubrication in one 1/2 in unit.
Step up or down through the 200/300/400/600 sizes to match the port and the flow your line needs - the 400 size with its 1/2 in PT port suits mid-to-large circuits. Choose the drain: differential-pressure (as fitted here) drains with flow, automatic (code A) drains on a timer-free cycle, manual (code M) needs an operator. Filter grade is 40 um standard; specify W for 5 um where finer particulate control matters. This unit is the low-pressure regulator type, so confirm your working band suits it before ordering. Gauge choices are embedded square (standard) or external round, with MPa, psi or bar scales - this configuration has a round psi gauge. Thread is PT as standard; G (BSPP) and NPT are order options. A mounting bracket is included. Flow is published as curves, not a single rating, so send us your application details 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 GR400-15 regulator with a GF400-15 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 rated flow number. Send us your application details and we will confirm the relevant flow-curve and datasheet figures for this 400-size, 1/2 in unit on request before you order.
The L in the code marks the low-pressure regulator type, intended for working bands below the standard regulator range; the exact adjustment range for this type is not published in our sheet, so confirm your working pressure with us before ordering. C2 in the code means an external round gauge scaled in psi is fitted; the embedded square gauge is the standard option, with MPa, psi or bar scales available.
