The AirTAC GC400C15C2K AirTAC F.R.L. Combination, PT1/2, 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400C15C2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one conditioned-air supply for a 1/2 in PT port. This configuration carries the standard 40 um filter element with a differential-pressure drain, a standard regulator adjustable over 0.15-0.9 MPa (20-130 psi), a fitted round gauge scaled in psi, and a reverse (check) valve that holds downstream pressure when the upstream supply is lost. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The filter and lubricator bowls on this 400 size are polycarbonate (PC); only the 600 size uses aluminium alloy bowls. A mounting bracket is included.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, G (BSPP) and NPT thread variants to order, 5 um (W) filtration as an option, automatic or manual drain choices, and gauge scale options in MPa, psi or bar. Flow is published by AirTAC as curves rather than a single rated figure, so we 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-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.

Feeds filtered, regulated and lubricated air to the clamping, tool-change and spindle-auxiliary circuits of a CNC machining centre, with the check valve holding the downstream circuit while the shop compressor cycles.
Conditions the air feeding cylinders and grippers on a carton-forming and sealing conveyor line, where the 40 um element protects valve spools and the lubricator carries oil mist to the actuators.
Serves as the point-of-use F.R.L. for air tools and spray equipment at an automotive paint booth, with the psi round gauge letting operators set and read line pressure directly in psi.
Start with the port step: this unit is the 400 size with a 1/2 in PT port, and the GC range steps through 200/300/400/600 with ports from 1/8 in to 1 in, so pick the size whose flow curve covers your demand rather than oversizing on port alone. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering. Decodable choices on this family: drain type (differential-pressure as here, automatic code A, or manual code M), filter grade (40 um standard, 5 um with code W), gauge style and scale (embedded square or external round; MPa, psi or bar), thread (PT standard, with G and NPT as order options), and the reverse/check valve (code K, fitted here). The regulator on this unit is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range for the differential-pressure drain configuration.
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 flow for the GC series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details and we will confirm the flow figures from the datasheet for this 400 size, 1/2 in PT unit before you order.
C2 decodes as a fitted external round gauge scaled in psi; the embedded square gauge is the standard fitting, and scales of MPa (code 1) or bar (code 3) are available as decodable options. Thread (PT standard, with G and NPT to order) and drain type (differential-pressure here, automatic or manual as options) are also selectable on this family.
