The AirTAC GC40015LF2GK AirTAC F.R.L. Combination, G1/2 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 GC40015LF2GK is an AirTAC GC series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled into one complete air-treatment set. This configuration is built around a G1/2 (BSPP) port on the 400 size body. The filter element is the standard 40 um grade with a differential-pressure drain, the regulator is the low-pressure type fitted with an embedded square gauge scaled in psi, and a reverse/check valve is fitted downstream. The polycarbonate bowls on the filter and lubricator let you see water and oil levels at a glance, and a mounting bracket is included.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600, with port options, thread variants (PT standard; G and NPT to order), drain types, 5 um filtration (code W), gauge scales and bracket choices across the range. Published flow data appears as curves rather than a single rating, so ask us to confirm sizing and 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 treated air to a CNC machining centre's pneumatic clamps and tool-change cylinders: the filter strips water and swarf-laden particulate, the low-pressure regulator holds a steady supply pressure, and the lubricator mists oil to the actuators.
Installed at the drop of a carton-sealing and palletising line, conditioning the air that drives grippers, pushers and diverters so seals and cylinders run on clean, regulated, lubricated air through a full shift.
Mounted on a branch line serving looms and winding heads in a textile mill, where the three-unit set removes condensate and fibre dust, stabilises branch pressure on the low-pressure setting, and oils the air feeding the machines' pneumatic components.
Start with the port and size: this unit steps up to 1/2 in on the 400 size, the right choice when your line's air consumption sits above what 3/8 in and smaller units comfortably serve. Because published flow is shown as curves rather than a single rated figure, send us your demand estimate and we will confirm the fit before you order. The regulator here is the low-pressure type; its exact adjustment range is not published, so confirm it against your working pressure with us. Choose the drain to match maintenance access: differential-pressure (as fitted here) drains with flow, automatic (code A) needs no attention, manual (code M) needs a periodic twist. Filtration is 40 um as standard; specify 5 um (code W) if downstream valves or instruments need finer air. Gauge scale is psi on this unit; MPa and bar scales are alternatives. Thread is G (BSPP) here, with PT standard and NPT orderable. Brackets are included on this configuration.
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 this series as performance curves rather than 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 sizing from the datasheet curves on request before you order.
The L in the code GC40015LF2GK selects the low-pressure regulator type, intended for applications whose working pressure sits below the standard regulator's range; its exact adjustment range is not published, so confirm it with us. The F2 selects the embedded square gauge scaled in psi; MPa and bar scales, and an external round gauge, are available as alternatives.
