The AirTAC Airtac GFC Combination Unit GFC400C15N is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with See datasheet ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).
GFC400C15N is a genuine AirTAC G-series two-unit set combining a filter-regulator with a lubricator, so filtration, pressure regulation and oil-mist lubrication of compressed air come from a single order. This size 400 configuration is ported 1/2 in with PT thread as standard and carries the default 40 um filter grade, which suits general plant air feeding cylinders, directional valves and blow-off points. The bowls use the default differential-pressure drain, the regulator adjusts from 0.15-0.9 MPa (20-130 psi), and neither a gauge nor a check valve is fitted. Maximum working pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C.
The G-series two-unit family spans sizes 200, 300, 400 and 600, with differential-pressure, automatic or manual draining, 40 um standard or 5 um fine filtration, gauge options, check-valve variants, and G (BSPP) or NPT threads as catalogue alternatives to the standard PT. On this size both bowls are polycarbonate. Flow for the series is published as curves rather than a single rated figure, so we confirm datasheet and flow 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 set has no separate bracket code — the two 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 set. Constituent units, orderable separately as spares: GFR400-C1 filter regulator and GL400-C1 lubricator.
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Feeds air-nozzle blow-off points along a packaging conveyor, where 40 um general-purpose air is adequate and the lubricator keeps the drive cylinders running smoothly through each shift.
Installed on a main air drop serving a production bay, filtering and regulating the supply for a mix of cylinders, clamps and hand tools, with the lubricator dosing whatever air tools hang on the line.
Prepares air for swing clamps and support cylinders on a machining fixture, holding a stable regulated pressure for repeatable clamping without needing a gauge at the set.
This is the straightforward configuration of the set: size 400 with a 1/2 in PT port, default 40 um filtration and the default differential-pressure drain. If your flow demand is larger or smaller, step up to GFC600 or down to GFC300 for a different port size. Choose the 5 um (W) variant if the same air line feeds spraying, instrumentation or sensitive valves; stay with 40 um for general actuation. The regulator covers 0.15-0.9 MPa (20-130 psi) on this drain version, and no gauge is fitted, so add one if operators need to read the set pressure.
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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR400-C1 filter regulator on its own.
The G-series flow data is published as curves, not as a single rated number, so we do not state one figure here. This size 400 unit with its 1/2 in port serves mid-to-high demand circuits in the family. Tell us your required flow and we will confirm the datasheet curves and figures for this exact model on request.
Differential-pressure draining is the default on this series: condensate is discharged in response to a pressure differential, with no daily visit needed. The alternative automatic drain expels condensate continuously, while the manual drain is emptied by hand and widens the regulator range to 0.05-0.9 MPa (7-130 psi) instead of 0.15-0.9 MPa (20-130 psi). We can quote any of the three drain versions of this model.
