The AirTAC GC400C10AF2WK 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 GC400C10AF2WK is an AirTAC GC series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one treatment stack for compressed air. This size 400 configuration is threaded PT3/8 (3/8 in), carries the 5 um filter element (code W) instead of the standard 40 um, drains condensate automatically, and regulates downstream pressure across the standard 0.15-0.9 MPa (20-130 psi) range. The regulator is the standard type and is fitted with an embedded square gauge scaled in psi, and a reverse/check valve is included so upstream pressure loss does not back-feed the circuit. Mounting brackets are included for panel or wall fixing.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT available as order options, plus a choice of drain type, filter grade, gauge scale and reverse valve. 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 rated figure, so ask us to confirm the datasheet and sizing for your application 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.

Feeding cleaned, regulated and lubricated air to the tool-change clamps and pneumatic actuators on a machining centre, where the 5 um element protects precision valves from fine particulate.
Conditioning the air feeding conveyor diverters and carton-forming cylinders on a packaging line, with the automatic drain handling condensate between shifts without operator attention.
A single treatment point at the drop of a robotic assembly cell, combining water and particle removal, stable regulated pressure on the psi gauge, and oil-mist lubrication for the cell's air cylinders.
Size 400 with a 3/8 in PT port sits in the middle of the GC range; step up to size 600 or down to 300/200 depending on the flow your line needs and the porting already installed. Choose the drain to match maintenance access: this unit has the automatic drain (code A), which suits unattended or hard-to-reach installations, while manual and differential-pressure drains are available on other codes. The 5 um element (code W) is the finer of the two published grades and is the right pick when downstream valves and cylinders need cleaner air than the standard 40 um element provides; the standard 40 um grade remains available if coarse water and particulate removal is enough. The fitted square gauge reads in psi; MPa and bar scales, and an external round gauge, are order options. Thread is PT as standard, with G (BSPP) and NPT selectable at order time, and a reverse/check valve (code K) is fitted on this unit. Flow for this family 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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number here. Tell us your application and we will confirm the flow figures from the datasheet on request before you order.
The A in the code sets the automatic drain, which ejects collected condensate without manual intervention - useful where the unit is mounted in a hard-to-reach spot. The W sets the 5 um filter element, one grade finer than the standard 40 um element, for cleaner air to downstream valves and cylinders. Both choices are decodable from the model code.
