The AirTAC GC400C15F2WG AirTAC F.R.L. Unit, G1/2 (1/2 in), 5 um 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 GC400C15F2WG is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one compressed-air treatment set. At this size 400 configuration it handles 1/2 in ports (G thread, with PT as the standard thread and G/NPT available as order options), filters to a fine 5 um grade (code W), regulates with the standard type over 0.15-0.9 MPa (20-130 psi), and meters oil mist to downstream actuators. The filter uses a differential-pressure drain, the regulator carries an embedded square gauge with a psi scale, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades (40 um standard, 5 um with W), gauge scales (MPa, psi or bar) and thread options. Bowl material follows size: polycarbonate on 200/300/400 and aluminium alloy on 600. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet and sizing figures 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.

Conditioning the shop-air feed to a CNC machining centre: the filter removes water and fine particulate before the regulator sets a stable pressure for tool-change cylinders and clamps, while the lubricator mists oil to keep pneumatic actuators running smoothly.
Treating air at the drop points feeding a paint-shop line: the 5 um grade strips water and particles that would spoil finish quality, the regulator holds a steady setting for spray and transfer operations, and the lubricator serves the air-driven equipment downstream.
Feeding the pneumatic cylinders and air motors on a packaging and cartoning line: clean, regulated, oil-misted air keeps sealing jaws, pushers and diverters cycling consistently through shift after shift of production.
Start with the port and size step: this unit is size 400 with a 1/2 in port, the larger of the mid-range steps - match it to the pipe size and required air demand of the circuit, and step up or down within the 200/300/400/600 range if the demand differs. Choose the drain on the filter: differential-pressure (as fitted here, draining on a set pressure differential), automatic, or manual. Choose the filter grade: 40 um standard or 5 um (W) where finer particulate removal is wanted - this unit carries the 5 um grade. Pick the gauge scale (MPa, psi or bar) and the thread: PT is the standard, with G and NPT as order options; this unit is specified with G thread. A bracket is included, and a reverse/check valve can be specified where needed. Because flow is published as curves and not as a single rating, 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 rather than a single rated figure, so there is no one rated-flow number we can quote. Tell us your operating pressure and air demand and we will confirm the flow and sizing against the datasheet on request before you order.
The W in the model code specifies the 5 um element; the GC series standard grade is 40 um. The 5 um grade suits circuits where finer water and particulate removal protects downstream valves and cylinders. Drain type (differential-pressure, automatic or manual), gauge scale and thread (PT standard, G or NPT to order) are also selectable when you specify the unit.
