The AirTAC GC40015F2GK AirTAC F.R.L. Combination, G1/2 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 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015F2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is built for a G1/2 (1/2 in) port on the G-thread version, with the standard 40 um filter element and a differential-pressure drain on the filter bowl. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and it carries an embedded square gauge reading in psi; an external round gauge is available as an option. A reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600, so the same three-unit concept can be stepped up or down in port size and flow capacity as your line requires. Filter grade (40 um standard, 5 um with the W code), drain type, gauge scale (MPa, psi or bar) and thread (PT standard, with G and NPT as order options) can all be selected per model. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the 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.

Feeds filtered, regulated and lubricated air to a machine tool's pneumatic tool-changer and clamping circuits, with the psi gauge letting operators set and check the regulator setting at the machine.
Mounted at the drop feeding a packaging line's cylinders and air-driven labellers: the filter removes water and particulate, the regulator holds a stable setting, and the lubricator mists oil for the actuators.
Installed where a factory air main branches to a work cell, conditioning the supply for downstream valves and tools in one assembly, with the included bracket fixing the set to the cell frame.
Choose the GC size by port and required flow: size 400 covers a 1/2 in connection, with 200, 300 and 600 stepping down or up. For the filter stage, the standard 40 um element suits general plant air; specify the W code for 5 um where finer particulate removal is needed. Drain choice matters: differential-pressure drain (this model), automatic drain for unattended condensate removal, or manual drain where an operator drains on a schedule. For the regulator, set the gauge scale you want to read - this unit is supplied with a square gauge in psi, with MPa and bar scales available. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order, so pick the one that matches your piping. A bracket is included for mounting.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the sizing against the datasheet curves 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 GR400-15 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 a flow number here. Tell us your line pressure and the air demand of your equipment, and we will confirm the sizing against the datasheet curves on request before you order.
A GC set is a separate filter, regulator and lubricator (three pieces), while a GFC combines the filter and regulator in one body and adds a separate lubricator - so GC gives you each stage as its own unit. This GC40015F2GK is the size 400 set for a G1/2 port, with a 40 um filter element, differential-pressure drain, standard regulator (0.15-0.9 MPa / 20-130 psi), an embedded square gauge reading in psi, a fitted reverse/check valve and an included mounting bracket.
