The AirTAC GC400C10AC2K AirTAC F.R.L. Combination, PT3/8 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 configuration, GC400C10AC2K, is the 400 size with 3/8 in PT ports. The filter element is the standard 40 um grade and the bowl carries an automatic drain, so collected condensate is expelled without manual attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a round gauge scaled in psi is fitted so the set downstream pressure can be read at a glance. A reverse/check valve (code K) is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options across drain type, filter grade (40 um standard, 5 um with code W), gauge style and scale (MPa, psi or bar), thread (PT standard, G and NPT to order) and reverse valve. Flow figures for this series are published as curves rather than a single rating, 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.

Feeding spray guns and air-assisted applicators on a finishing line: the filter removes water and particulate, the regulator holds a steady set pressure for consistent atomisation, and the lubricator mists oil to the air motor or cylinder circuit downstream.
Conditioning the 3/8 in supply to a conveyor-mounted case-packer or palletiser where clamp and pusher cylinders run continuously: clean, regulated, lubricated air with an automatic drain so the bowl empties itself between shifts.
Supplying a CNC fixture or workholding clamping circuit where steady regulated pressure protects the clamping sequence, the check valve helps hold the set condition, and the psi gauge lets the setter verify the clamp pressure at the panel.
Start with the size and port: the 400 body in 3/8 in PT suits lines where the supply main and downstream cylinder or valve ports are 3/8 in; step up or down a size if your flow demand sits at the edge of the curve. Choose the drain next: this unit has an automatic drain, which suits unattended or hard-to-reach installations; manual and differential-pressure drain versions exist if you prefer scheduled or load-proportional draining. The 40 um element is the standard grade for general plant air; specify code W (5 um) only where finer particulate capture is needed. The fitted round gauge here reads in psi; square embedded gauges and MPa or bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the bracket is included.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the datasheet figures against your demand 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 the GC series as performance curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your working pressure and air demand and we will confirm the datasheet curve figures against your application before you order.
GC combines a separate filter, regulator and lubricator, so it is the choice when the downstream equipment needs oil-mist lubrication as well as filtered, regulated air; a two-unit GFC set omits the lubricator. This configuration also has an automatic drain on the filter bowl, which expels collected condensate by itself instead of waiting for a manual drain, and a reverse/check valve (code K) is fitted.
