The AirTAC GFC Combination Unit GFC300C15N 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).
GFC is the AirTAC two-unit air preparation set: a filter regulator and a lubricator supplied as one matched pair, so a single part number covers water and particle removal, pressure regulation and oil-mist lubrication. This 300-size set is piped at 1/2 in on the standard PT thread and stays with the catalogue defaults: the 40 um standard filtering element and the default differential-pressure drain rather than a hand-opened or fully automatic one. The regulator adjusts from 0.15-0.9 MPa (20-130 psi), maximum working pressure is 1.0 MPa (145 psi), the bowls are PC (polycarbonate) at this size, the mounting bracket is included, and no gauge is specified on this code.
This is a genuine AirTAC part. The G series spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT to order, 40 um standard or 5 um elements, differential-pressure, automatic or manual drains, and -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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: GFR300-C1 filter regulator and GL300-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.

Runs the pneumatic diverters and stopper cylinders along a bottling hall conveyor, with the default differential-pressure drain suiting a line that has no dedicated drain routine each shift.
Feeds the selvedge cutters and doffing cylinders on weaving machines, where the standard 40 um element matches general cylinder and valve duty.
Mounted inside a machine's pneumatic cabinet to condition the air feeding the valve manifold before it reaches the actuators downstream.
Size 300 with a 1/2 in PT port is the step once a line outgrows 1/4 or 3/8 in piping; move up to size 400 (3/4 in) or size 600 (1 in) for larger demand. This code keeps the defaults on every option: 40 um filtration for general cylinder and valve service, the differential-pressure drain, no reverse valve, and no gauge on the regulator - the G series can carry an embedded square or external round gauge if you specify it instead. Thread is PT as standard with G (BSPP) and NPT as orderable options, and the 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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR300-C1 filter regulator on its own.
G-series flow data is published as curves rather than a single rated figure, so no one number is quoted here. Share your working pressure and air demand and we will confirm the flow and datasheet figures for this model on request.
A GFC pairs the filter regulator and lubricator as one matched set, so you order and mount a single part number with matched ports and a shared bracket. If your line needs a separate three-piece F.R.L. stack, the GC family covers that layout in the same sizes.
