The AirTAC GC40010AF2WGK AirTAC F.R.L. Combination, G3/8 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 PT3/8" ports, a 5 µm element, a automatic 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 coordinated set to clean, regulate and lubricate compressed air. This GC40010AF2WGK is the 400 size with G3/8 ports and G thread. The filter carries the 5 um element (code W) with an automatic drain, so collected condensate is discharged without manual attention. The standard-type regulator adjusts from 0.15-0.9 MPa (20-130 psi) and is fitted with an embedded square gauge reading in psi; a reverse/check valve is fitted and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the PC (polycarbonate) bowls suit this 400 size - only the 600 size uses aluminium alloy bowls.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600, with port, thread (PT standard; G and NPT as order options), drain type, filter grade, gauge scale and check-valve choices across the range. 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: GF400-10 filter, GR400-10 regulator and GL400-10 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 paint line, where the 5 um element, stable regulated pressure and oil-mist lubrication support consistent finish work.
Supplying the pneumatic cylinders and grippers that drive carton erecting, filling and sealing stations, with lubricated air helping seals and actuators run smoothly through long shifts.
Mounted in the air-preparation panel of a CNC machine or assembly cell, providing cleaned, regulated and lubricated air to clamps, tool-changers and actuated gates, with the check valve guarding against backflow.
Start with the size and port step: 200, 300, 400 and 600 cover increasing port sizes and flow capacity, so match the size to the air demand of the downstream circuit - here the 400 size with G3/8 ports. Then settle the decodable options: drain type (differential-pressure as the default, automatic for hands-off condensate discharge, or manual), filter grade (40 um standard or 5 um with code W for finer particulate), gauge scale (MPa, psi or bar, embedded square as standard with an external round gauge optional), thread (PT standard, G or NPT to order), bracket, and for the regulator a reverse/check valve if backflow protection is needed. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 GR400-10 regulator with a GF400-10 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. Tell us your application and required air demand and we will confirm the sizing from the datasheet on request.
The W in the code specifies the 5 um element instead of the 40 um standard, for finer particulate removal, and the A specifies an automatic drain, so condensate collected in the filter bowl is discharged without manual attention. If your circuit tolerates coarser filtration and manual draining, the 40 um / manual-drain configuration is also available in the series.
