The AirTAC GC300C08LC2K 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 AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one air-preparation set. This GC300C08LC2K is the size 300 unit with a PT1/4 (1/4 in) port. The filter element is the standard 40 um grade and the bowl uses a differential-pressure drain, which bleeds accumulated water automatically whenever the pressure differential across the element is high enough. The regulator is the low-pressure (L) type and carries a round gauge reading in psi; a reverse/check valve is fitted to hold downstream settings if the supply is interrupted, and the set includes a mounting bracket.
This is a genuine AirTAC part. The GC line is offered in sizes 200, 300, 400 and 600 with a choice of ports, drain types, 40 um or 5 um (W) filtration, gauge style and scale, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure against your application before ordering.

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.

Feeds cleaned, regulated and lubricated air to the clamping cylinders and tool-change actuators on a machining centre, with the check valve helping hold the clamp circuit if shop air drops.
Supplies the diverters, sealers and pick-and-place cylinders on a carton packaging conveyor with filtered, pressure-controlled, oil-misted air in one mounted set.
A complete conditioning point for a plant maintenance drop, where hand tools, impact wrenches and test rigs all need water- and particle-free air at a set low pressure.
Start with the port: this unit is PT1/4, and the GC series steps up through sizes 200, 300, 400 and 600 as your air demand grows - match the size to the flow your line needs rather than to the pipe alone. The filter ships with the standard 40 um element; specify the W suffix if your downstream equipment needs the finer 5 um grade. Drain choice matters: differential-pressure (this unit) drains on demand, while automatic and manual variants are available. The regulator here is the low-pressure (L) type with a round psi gauge; other gauge styles and MPa/bar scales exist, as do PT, G and NPT thread options. Because flow is published only as curves and not as a single rating, send us your application details and we will confirm sizing from the datasheet before you order.
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 series as curves, not as a single rated figure, so we do not quote a number on the page. Send us your application details and we will confirm the flow and sizing from the datasheet on request.
The L code marks the low-pressure regulator type rather than the standard one, so this set is intended for circuits controlled below the usual working band. The exact adjustment range for the low-pressure variant is not published on our sheet - ask us and we will confirm it from the AirTAC datasheet before you order.
