The AirTAC GC40015AF2G 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015AF2G 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. It cleans compressed air (removing water and particulate down to 40 um), regulates downstream pressure within a 0.15-0.9 MPa (20-130 psi) adjustment range, and adds oil mist for air-powered tools and actuators. This unit is sized for 1/2 in ports with G thread, uses the standard (non low-pressure) regulator, and carries an automatic drain on the filter bowl so collected condensate is expelled without manual attention. The polycarbonate bowl is fitted with an embedded square gauge reading in psi, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with a choice of drain type (differential-pressure, automatic or manual), a 5 um filter element option, gauge scale (MPa, psi or bar), and PT, G or NPT thread. Rated flow is published only as curves rather than a single figure, 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: GF400-15 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 spray booths and air-driven agitators on a paint line, where water and particulate in the supply would otherwise mar the finish and the automatic drain keeps condensate off the work.
Conditions the shop-air feed to CNC machining centres and their pneumatic tool changers, holding steady regulator pressure for clamping circuits and delivering oil mist to air cylinders and spindles.
Serves the pneumatic cylinders and air-driven sealers on a carton packaging conveyor, with the 1/2 in port sized for the line's air demand and the automatic drain protecting valves between shifts.
Start with the port and size step: this unit is the 400 size with 1/2 in ports, one step above the 300 series - if your line flow demand is near the top of the 300 size, step up rather than oversizing the regulator range. The automatic drain suits unattended or hard-to-reach installations; choose manual drain where you prefer controlled, scheduled blowdown, or the differential-pressure default where drain effort should stay minimal. The standard 40 um element covers general plant air; specify the W code for a 5 um element where finer filtration is needed. The fitted square gauge reads in psi; MPa and bar scales are available, and an external round gauge is optional. Thread here is G (BSPP); PT is the catalogue standard and NPT is an order option - select to match your piping. 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 this series as curves rather than a single rated figure, so no single number would be honest to quote. Tell us your line pressure and air demand and we will confirm the flow from the datasheet and check the 400 size against your application before you order.
The A in the code GC40015AF2G selects the automatic drain, which expels collected condensate from the filter bowl without manual attention - useful where the unit is mounted in a hard-to-reach spot. The GC series is also available with a manual drain or the differential-pressure default; choose the drain code that matches how the unit will be serviced.
