The AirTAC GC400C10LC2K AirTAC F.R.L. Combination, PT3/8, 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 AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one air-treatment set. This GC400C10LC2K is the size 400 unit with PT3/8 ports (PT thread standard). The filter element is the standard 40 um grade for water and particulate removal, with a differential-pressure drain that discharges collected condensate as the pressure differential across the element builds. The regulator is the low-pressure type, and a round gauge with a psi scale is fitted. A reverse (check) valve is included, and the set is supplied with a mounting bracket.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with a choice of PT, G or NPT thread, 40 um or 5 um (W) filtration, manual, automatic or differential-pressure drains, gauge scale options, and standard or low-pressure regulation. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm 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.

Feeding filtered, regulated and lubricated air to a machining centre's clamps, tool changer and pneumatic cylinders, with the low-pressure regulator and psi gauge suiting a controlled machine-air circuit.
Conditioning the air supply to conveyor stoppers, diverters and pusher cylinders on a packaging line, where the 40 um element protects valves and the lubricator keeps actuator seals working.
Serving point-of-use drops on an assembly line that runs pneumatic impact wrenches and nutrunners, giving each station filtered, pressure-controlled and oil-misted air from one bracket-mounted set.
Size 400 with PT3/8 ports sits in the middle of the GC range; step up to size 600 or down to 300/200 depending on the pipe size and flow your line needs. Drain choice matters: the differential-pressure drain fitted here discharges automatically as the element loads, while automatic (A) and manual (M) versions are orderable. The standard 40 um element suits general plant air; specify the W code for 5 um where downstream equipment needs finer filtration. This unit carries the L code for low-pressure regulation - the exact adjustment range for the low-pressure type is not published, so confirm it with us against your set pressure before ordering. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the alternative. PT is the standard thread; G and NPT are order options. Bracket included.
Flow for this series is published as curves, not a single rated figure, so send us your application details 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 curves rather than a single rated figure, so we do not quote a number. Send us your application details and we will confirm the sizing from the datasheet on request before you order.
The L means the regulator is the low-pressure type rather than standard, and the exact adjustment range for the low-pressure version is not published - confirm it with us. The blank drain position means a differential-pressure drain: condensate in the filter bowl is discharged automatically as the pressure differential across the 40 um element builds, with no manual draining needed.
