The AirTAC GFC Combination Unit GFC300C15C1K 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).
GFC300C15C1K is a two-piece AirTAC G-series air-treatment set: a filter regulator plus a lubricator, with a reverse (check) valve fitted as denoted by the K in the code. It removes water and particulate, regulates downstream pressure and adds oil mist, while the check valve holds the downstream circuit against backflow from the supply side. This configuration is sized 300 with a PT1/2 port (PT thread as standard), a differential-pressure drain, the standard 40 um element and a round gauge with MPa scale. Regulation covers 0.15-0.9 MPa (20-130 psi) with this drain type; the set carries compressed air at up to 1.0 MPa (145 psi) and works from -5 to 70 C (non-freezing). Both bowls on this 300 size are PC (polycarbonate).
This is a genuine AirTAC part sold by a distributor for the US market. The G-series spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, plus drain choices, 5 um (W) elements, gauge types and scales and G (BSPP) or NPT threads. AirTAC publishes flow as curves rather than a single rating, so share your application details and we will confirm sizing and datasheet 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.

Conditions the air feeding star-wheel, capper and filler cylinders on a bottling line, where the check valve helps the circuit hold its set pressure through supply dips between fill cycles.
Supplies the gripper and clamp circuits on a robot cell with clean, regulated, lubricated air, while the reverse valve keeps the gripper circuit isolated from upstream pressure fluctuation.
Prepares the pilot and actuator supply for pneumatically actuated process valves, pairing the filter regulator with the lubricator so the actuator cylinders and pilot valves run on conditioned air.
The 300 size with a 1/2 inch PT port sits mid-range in the G-series; step to 200, 400 or 600 sizes if the flow curve for your circuit points elsewhere. The K option adds a reverse (check) valve, useful where a downstream circuit must hold pressure if the upstream supply drops; order the same code without K if you do not need it. This unit uses the differential-pressure drain, with automatic (A) and manual (M) drains available as catalogue options. The standard element is 40 um, and W gives 5 um. A round MPa-scale gauge is fitted; other gauge types and scales can be ordered. Thread is PT as standard, with G (BSPP) and NPT available to order, and a bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing 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.
AirTAC publishes G-series flow data as curves rather than a single rated figure, so there is no one rated flow number to quote. Tell us your working pressure and consumption and we will confirm sizing from the datasheet on request.
It indicates that a reverse (check) valve is fitted, which blocks backflow from the downstream side toward the supply. The same set without the K suffix is available if your circuit does not need this function.
