The AirTAC GC40015MC2WG AirTAC F.R.L. Combination, G1/2 (1/2 in) 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC400 series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one supply unit. This configuration is built with a G1/2 (1/2 in) port, a 5 um filter element for finer water-and-particulate removal than the standard 40 um grade, and a manual drain you operate by hand to empty collected condensate from the filter bowl. The regulator is the standard type with a 0.05-0.9 MPa (7-130 psi) adjustment range, a round external gauge scaled in psi is fitted, and a 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, and options include thread choice (PT standard; G and NPT orderable), automatic or differential-pressure drain, 40 um or 5 um filtration, gauge style and scale, and a reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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 0.05 - 0.9 MPa (7 - 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.

Feeds filtered, regulated and lubricated air to the drawbar and clamp actuators on a machining centre, where the 5 um element protects the clamping valve and steady oil mist keeps the mechanism moving freely.
Supplies conditioned air to the cylinders and grippers on a carton-forming and sealing line, with the regulator holding a set working pressure so the packing sequence repeats consistently through the shift.
Conditions the air feeding impact wrenches, ratchets and air hammers at a maintenance bench, where the lubricator's oil mist extends tool life and the manual drain lets the operator clear condensate at the start of each day.
Start with the port step: the 400 size carries a 1/2 in port, and moving up or down a size changes both the connection and the airflow path, so match the size to the demand of the downstream circuit. Choose the drain to suit access: manual drain (this unit) needs someone to open it periodically, while automatic and differential-pressure drains discharge condensate without attention. Pick the filter grade for the job: 40 um is the standard element, and the W option (fitted here) gives 5 um for finer protection. The gauge is supplied as a round external gauge on this unit, scaled in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. Thread is G on this model, with PT as the standard and G/NPT as orderable options, and a mounting bracket is included. 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote one number. Send us your application details and we will confirm the relevant flow and datasheet figures for this unit on request.
The M in the code is a manual drain: condensate collected in the filter bowl is released by hand, so the unit needs periodic attention (automatic and differential-pressure drains are available as options). The W code is the 5 um filter element, a finer grade than the standard 40 um, suited to protecting sensitive downstream valves and actuators.
