The AirTAC GC400-15G AirTAC F.R.L. Combination Unit, 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC400-15G is a three-piece AirTAC F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one set so the air line is cleaned, regulated and lubricated at a single mounting point. This size 400 unit is fitted with a G1/2 (BSPP) port, a manual drain on the filter bowl, the standard 40 um filter element and an embedded square pressure gauge scaled in psi. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The bowls are polycarbonate (PC) at this size, and a mounting bracket is included.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard; G and NPT as order options), drain types (differential-pressure, automatic or manual), filter grades (40 um standard, 5 um with code W) and gauge scales (MPa, psi or bar). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 0.05 - 0.9 MPa (7 - 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.

Installed at the point where the main header feeds a production department, the set removes water and particles, holds a steady regulated pressure for the tools on that drop, and carries oil mist downstream to keep air cylinders and valves running smoothly.
Mounted on the frame of a packaging or conveyor line, the combination feeds the line's actuators, grippers and air jets with clean, regulated and lubricated air, with the included bracket giving a fixed mounting point near the line's air inlet.
Used by machine builders and maintenance teams when fitting out or upgrading a pneumatic panel on a press, CNC peripheral or assembly machine, providing filtration, pressure adjustment and lubrication in one assembly with a psi gauge to match US practice.
Start with the size and port: 200, 300, 400 and 600 step up in port size and flow capacity, so match the size to the air consumption of the downstream equipment - here size 400 with a G1/2 port. Choose the drain type: manual drain (this unit) needs periodic draining by hand, while automatic or differential-pressure drain types empty the bowl without operator attention. Choose the filter grade: 40 um is the standard element for general plant air; specify code W for the 5 um element where finer particle removal is needed. Pick the gauge scale (MPa, psi or bar) and the thread: PT is the standard, with G (BSPP) and NPT available as order options - this unit is supplied with G1/2. A bracket is included for mounting. Because flow is published as curves and not as a single rating, 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 the GC series as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow and sizing against the datasheet on request before you order.
This configuration carries code M, which means the filter bowl is drained by hand at intervals. If you prefer the bowl to empty without operator attention, the GC series is also available with automatic drain (code A) or differential-pressure drain (no code) - ask us to quote the variant you need.
