The AirTAC GC400C15C2GK 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC400C15C2GK is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This size 400 configuration is drilled for 1/2 in ports with G (BSPP) threads, carries the standard 40 um filter element with a differential-pressure drain on the filter bowl, and regulates from 0.15 to 0.9 MPa (20-130 psi). A round gauge reading in psi is fitted, a reverse/check valve is included, and a mounting bracket comes with the unit. The polycarbonate bowl suits the -5 to 70 C (non-freezing) operating range, with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in and options including 5 um filtration, automatic or manual drains, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow figures for the GC series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application.

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.

Dropping a filtered, regulated and lubricated air supply off the main ring main to feed a production cell, with the 40 um element catching pipe scale and water before actuators see the air.
Conditioning the air feeding cylinder-driven diverters, pushers and clamp stations on a packaging or conveyor line, where the regulator holds a steady working pressure and the lubricator mists oil to the cylinders.
Feeding a manifold of directional control valves and air actuators on automated machinery, with the check valve holding the downstream circuit and the psi gauge giving the operator a direct setpoint readout.
Start with the size and port: the GC series steps through sizes 200, 300, 400 and 600, and this unit sits at size 400 with 1/2 in G-threaded ports - step up or down a size if your line flow sits outside what a 1/2 in set comfortably handles, and ask us to confirm against the published curves. Next, choose the drain: this configuration uses the differential-pressure drain (automatic and manual drains are the coded alternatives), and note the regulation range is 0.15-0.9 MPa (20-130 psi) with this drain type. Filter grade is the standard 40 um element; the W code gives 5 um where finer particulate removal matters. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue choices. Thread is G here, with PT as the standard and NPT available to order, and the bracket is included. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing 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 GC series flow as performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the air demand of the equipment you are feeding, and we will confirm the flow and sizing from the datasheet on request.
The differential-pressure drain is the standard choice in this configuration: it bleeds condensate from the filter bowl automatically as flow passes through, with no operator attention. If you prefer a fully automatic float drain or a simple manual drain, those are the coded alternatives in the GC series - and note the regulation range is 0.15-0.9 MPa (20-130 psi) with the differential-pressure drain fitted.
