The AirTAC GC300C15AF2K AirTAC F.R.L. Combination, PT1/2, Auto Drain 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC300C15AF2K is a three-piece AirTAC F.R.L. combination: a filter, a pressure regulator and a lubricator assembled as one air-preparation set. This configuration is sized 300 with a PT1/2 (1/2 in) port, filters to 40 um, drains condensate automatically, regulates with the standard-type regulator over 0.15-0.9 MPa (20-130 psi), and meters oil mist to downstream air tools. The embedded square gauge reads in psi, a reverse/check valve is fitted, 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 port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge scale and thread form. Flow figures for this series are published as curves rather than a single rated number, so ask us and we will confirm the datasheet 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 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: GF300-C1 filter, GR300-C1 regulator and GL300-C1 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 clean, regulated and lubricated air to the clamping fixtures, tool-change actuators and air-powered spindle ancillaries on a CNC machining centre, with automatic drain keeping condensate out of the valves.
Prepares the air feeding carton-forming cylinders, sealing jaws and reject pushers on a packaging conveyor, so the cylinders run on filtered, pressure-stabilised, oil-misted air through a full shift.
Installed as the point-of-use F.R.L. on a drop line at an assembly plant bench, protecting impact wrenches, air ratchets and pneumatic screwdrivers with 40 um filtration, regulated pressure and consistent lubrication.
Start with the size and port: this unit is size 300 with a PT1/2 port, one step up from the 200/1/4 in class and one step below the 400/3/4 in class, so match the step to the air demand of the line. The drain here is automatic, which suits unattended installations; manual and differential-pressure drain variants exist if you prefer scheduled or load-linked draining. The filter element is the standard 40 um grade (a 5 um W-grade element is available in the family if finer particulate capture is needed). The fitted square gauge reads in psi; MPa and bar scales are alternatives. The thread is PT as standard, with G (BSPP) and NPT available as order options, and the bracket is included. Because flow for this series is published as curves rather than 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 GR300-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for the G series as curves rather than a single rated figure, so we do not quote one number here. Tell us your operating pressure and air demand and we will confirm the flow from the datasheet for this exact model on request before you order.
The A in the code means the filter bowl drains condensate automatically, which suits installations that run unattended. The GC family is also available with manual drain or the default differential-pressure drain, so you can pick the drain style that matches how the unit is maintained.
