The AirTAC GC300C08ALF2 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 GC300C08ALF2 is an AirTAC GC-series three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one treatment stack for a compressed-air line. This configuration is size 300 with a PT1/4 (1/4 in) port, PT thread as standard, a 40 um filter element with automatic drain, a metal bowl on the filter section, a low-pressure type regulator, and a fitted square gauge scaled in psi. No 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 options, drain types, filter grades (40 um standard, 5 um optional), gauge styles and scales, and G or NPT thread variants to order. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application.

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.

Installed at a workshop air drop to remove water and particulate, hold a steady low working pressure, and carry oil mist downstream to the tools and cylinders served by that drop.
Mounted on a CNC machine tool or press auxiliaries to condition the shop-air feed before it reaches clamps, tool-change cylinders and purge lines, with the psi gauge giving operators a local setpoint reference.
Fitted ahead of the valve manifold on a packaging or conveyor line so actuators receive filtered, regulated, lubricated air, with the automatic drain keeping condensate off the line during continuous shifts.
Choose the size and port step against the air demand of the line: this unit is size 300 with a PT1/4 port; larger sizes carry larger ports and more flow capacity. Drain type is a real choice in this family - differential-pressure (default), automatic (as fitted here, which spills condensate without manual attention) or manual. Filter grade is 40 um standard or 5 um with code W; gauge style is embedded square (standard) or optional external round, with MPa, psi or bar scales - this unit carries the square gauge in psi. Thread is PT as standard, with G (BSPP) and NPT as order options.
Flow for this family is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you order. The regulator in this unit is the low-pressure type; we will confirm its exact adjustment range on request.
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 number here. Tell us your line size and air demand and we will confirm the sizing from the datasheet on request before you order.
The A in the code sets the automatic drain, which expels collected condensate from the filter bowl without manual attention. The GC family also offers the differential-pressure drain (the default) and a manual drain; we can confirm the right choice for your installation on request.
