The AirTAC GC300C08AF2K AirTAC F.R.L. Combination, PT1/4 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 GC300C08AF2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one complete air-treatment set. This configuration is the 300 size with PT1/4 (1/4 in) ports, PT thread as standard, an automatic drain on the filter bowl, the standard 40 um filter grade, a fitted square gauge reading in psi, a reverse/check valve, and a mounting bracket included. The filter removes water and particulate, the regulator holds a stable downstream pressure adjustable from 0.15-0.9 MPa (20-130 psi), and the lubricator meters oil mist into the air line for downstream components. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The filter and lubricator bowls on this 300 size are polycarbonate.
This is a genuine AirTAC part. The GC family is available in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge scale, thread (PT standard, G and NPT as orderable options) and reverse/check valve. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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-C0 filter, GR300-C0 regulator and GL300-C0 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.

Clean, regulated and lubricated air for the tool-clamp and pallet-change cylinders on a machining centre, with the automatic drain carrying off accumulated condensate during long unattended shifts.
Feeding the pick-and-place and carton-sealing cylinders on a packaging conveyor, where stable regulated pressure keeps cycle behaviour consistent and oil mist lubricates the seals.
A point-of-use F.R.L. set at the air drop feeding impact tools and air cylinders at an assembly workstation, filtering shop-air water and particles and lubricating the tools downstream.
Choose the GC size by the port step your line needs: this 300 unit carries PT1/4 (1/4 in) ports, and the family steps up through 400 and 600 for larger ports and higher flow. Because flow is published as curves and not a single rating, ask us to confirm sizing against your air consumption before ordering. Decodable choices on this family: drain type (automatic as fitted here, or manual, or the differential-pressure default), filter grade (40 um standard as fitted here, or 5 um with code W), gauge scale (MPa, psi or bar), thread (PT standard, G/BSPP or NPT to order), and reverse/check valve (fitted here with code K). A mounting bracket is included on this unit. If you need only filtration or only regulation, the GF and GR families cover those separately; the GC three-piece set is the choice when filter, regulator and lubricator are all required.
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-C0 regulator with a GF300-C0 filter on that branch.
AirTAC publishes flow for this family as curves rather than a single rated figure, so we do not quote a rated flow, Cv or l/min number. Tell us your application and air consumption and we will confirm the flow and sizing figures from the datasheet on request before you order.
The GC combination is a separate filter, regulator and lubricator, so each element can be serviced or replaced on its own, and the lubricator sits after the regulator as a full three-piece F.R.L. train. The GFC two-unit set combines the filter and regulator in one body with the lubricator added, which saves space but couples the filter and regulator. This GC300C08AF2K has an automatic drain, a 40 um filter grade, a square psi gauge and a reverse/check valve fitted.
