The AirTAC GC40015F2WK AirTAC F.R.L. Combo 1/2 in PT, 5 um, psi gauge 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 PT1/2" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC40015F2WK is a three-piece F.R.L. combination that filters, regulates and lubricates compressed air from a single assembled set: a separate filter, a separate pressure regulator and a separate oil-mist lubricator. This size 400 configuration is built around a 1/2 in PT port, carries the fine 5 um filter element (code W) instead of the standard 40 um, and drains its filter bowl by differential pressure, so condensate is expelled when the pressure differential across the element builds. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), a square pressure gauge reading in psi is fitted, and a reverse/check valve is included to hold downstream pressure. The maximum working (inlet) pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and the filter and lubricator bowls on this size are PC (polycarbonate).
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with options across drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge scale (MPa, psi or bar) and thread (PT standard, with G and NPT as orderable options). Flow for this series is published as curves rather than a single rated figure; ask us and we will confirm the flow and datasheet 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: GF400-15 filter, GR400-15 regulator and GL400-15 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 a production hall's distribution manifold, the GC40015F2WK cleans water and particles down to 5 um, holds a set working pressure for the actuators on the line, and carries oil mist downstream to lubricate the cylinders and valves that cycle all shift.
On a packaging line where pneumatic diverters, clamps and pushers run continuously, this three-unit set conditions the supply at the line drop: filtered to 5 um, regulated to the pressure the machine was set up for, and lubricated so the air cylinders keep sealing and sliding smoothly.
For a pneumatic test bench or lab rig that needs clean, stable, lubricated air at a fixed setting, the 5 um element protects sensitive instrumentation, the psi gauge and regulator give a readable, repeatable setpoint, and the check valve holds the setting if supply pressure dips.
Start with the port and size step: this unit is size 400 with a 1/2 in PT port, one step up from the 300 series, so choose it when your line's flow demand sits above what the smaller ports serve - and ask us to confirm the sizing, because flow is published as curves, not a single rating. Next, the drain: this configuration uses the differential-pressure drain (the default); automatic drain (code A) and manual drain (code M) are available if you prefer hands-off or scheduled condensate removal. The filter grade here is the fine 5 um element (code W); the standard element is 40 um, so pick 5 um where downstream equipment needs finer particle removal. The fitted square gauge reads in psi; MPa and bar scales, and an external round gauge, are alternatives. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and a mounting bracket is included. Before ordering, send us your application details and we will confirm the flow figures against the datasheet.
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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated number, so we do not quote a figure that could mislead your sizing. Tell us your application and operating pressure and we will confirm the flow figures from the datasheet on request before you order.
In the code GC40015F2WK, the W sets the fine 5 um filter element (the standard element is 40 um) and F2 sets the fitted square gauge with a psi scale. Both are real catalogue choices: 40 um is available where coarse filtration is enough, and the gauge can be ordered with MPa or bar scales, or as an external round gauge. The thread is PT as standard, with G (BSPP) and NPT as orderable options.
