The AirTAC GC40015F2G AirTAC F.R.L. Combination, G1/2 (1/2 in) Port 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 AirTAC GC40015F2G is a three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator set up as one coordinated air-preparation package. This configuration is built around a 1/2 in port (G thread) in the GC400 size, with the filter element at the standard 40 um grade for general-purpose water and particulate removal, a differential-pressure drain on the filter bowl, and a standard regulator fitted with an embedded square gauge reading in psi. The lubricator meters oil mist into the downstream air for pneumatic tools and cylinders that need lubrication. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The bowls on the 400 size are polycarbonate (PC), and a mounting bracket is included.
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600 with matching port sizes, and can be ordered with alternative drain types, a 5 um filter grade, different gauge scales, and PT, G or NPT threads. Because flow is published as curves rather than a single rated figure, contact us and we will confirm the flow and datasheet figures for this exact model against 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: GF400-15 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 filtered, regulated and lubricated air to the pneumatic clamps, tool-change cylinders and chip-clearing jets on a CNC machining centre, where the 40 um element handles general shop-air moisture and particles and the lubricator keeps cylinder seals working.
Air preparation for the forming and case-sealing cylinders on a packaging conveyor, where the regulator holds a steady setting through shift-long cycling and the differential-pressure drain clears collected water without a manual walk-round.
Supplying air to impact wrenches, nutrunners and air ratchets at an assembly cell, where the three-unit set filters the supply, holds the working pressure the tools were set up for, and carries oil mist downstream to lubricate the tools themselves.
Start with the size and port: GC400 carries a 1/2 in port, and the 200/300/400/600 size steps exist so you can match the unit to the flow your line needs - if your demand sits near the top of a smaller size, step up. From there the real choices are: drain type on the filter bowl (differential-pressure as here, automatic, or manual); filter grade (40 um standard, 5 um where finer filtration is required); gauge scale (MPa, psi or bar, with an external round gauge available as an option); thread (PT is the standard, with G and NPT as catalogue options - this unit is the G version); and bracket mounting. A reverse/check valve is not fitted on this code.
One honest note on sizing: AirTAC publishes flow as curves, not as a single rated number, so we do not quote a flow figure here. Ask us to confirm the flow and datasheet figures for the GC40015F2G against your application 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 curves rather than a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the flow and datasheet figures for this exact model against your demand before you order.
The blank drain code on GC40015F2G means a differential-pressure drain: it discharges collected condensate when the pressure differential across the filter builds up, with no operator action. You can instead order an automatic drain (code A) or a manual drain (code M) on the same size if your maintenance routine suits those better.
