The AirTAC GC40010F2WK 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 PT3/8" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40010F2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one prepared-air station. This size 400 unit is built for 3/8 in PT ports and carries the 5 um filter element (code W) for finer water and particulate removal than the standard 40 um grade. The filter bowl drains by differential pressure, the regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and the embedded square gauge reads in psi. A reverse/check valve 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, plus options for drain type, filter grade, gauge scale and G or NPT threads. Flow for this series is published as curves rather than a single rated figure, 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: GF400-10 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.

A bottling plant's conveyor stopper and pusher cylinders run continuously on plant air. This F.R.L. station removes water and fine particulate at 5 um, holds a steady regulated pressure, and carries oil mist to the cylinders, with the differential-pressure drain clearing condensate as the line runs.
Impact wrenches, ratchets and air screwdrivers at an assembly cell need clean, lubricated air at a fixed setting. The three-unit layout lets the shop filter to 5 um, lock the regulator at the tool's working pressure read on the psi gauge, and feed oil mist in one mounted assembly.
Pneumatic clamps and tool-change actuators on a CNC machining centre demand stable, dry, lubricated air. The 5 um element protects the machine's valves, the reverse/check valve holds the circuit against backflow, and the bracket mounts the station at the machine's air inlet.
Work size and port from the air demand of the circuit: the 400 size with its 3/8 in PT port sits mid-range in the GC series (200/300/400/600), so step up or down if the connected flow sits near the edge of the published curve. Choose the drain to match maintenance practice: differential-pressure (as fitted here) drains automatically while the unit flows, automatic drains on a set schedule, and manual requires someone to open the bowl. Filter grade is 40 um standard or 5 um with the W code, which this unit carries; pick 5 um where downstream valves and cylinders are more sensitive. Gauge scale is MPa, psi or bar, and threads can be ordered in PT (standard), G (BSPP) or NPT. Brackets are included on this configuration.
Because flow is published as curves rather than a single rated number, 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 GR400-10 regulator with a GF400-10 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 or SCFM number on the page. Send us your line pressure and the air demand of your equipment, and we will confirm the sizing from the datasheet on request before you order.
The W code in GC40010F2WK selects the optional 5 um grade in place of the 40 um standard element. The finer grade suits circuits with sensitive valves, cylinders or instrumentation downstream. If your application tolerates coarser filtration, the same size is available with the standard 40 um element.
