The AirTAC GC30008LC2 AirTAC F.R.L. Combination, PT1/4, Low-Pressure 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 PT1/4" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30008LC2 is an AirTAC three-piece F.R.L. combination that conditions compressed air in one assembly: a filter removes water and particulate down to the standard 40 um grade, a low-pressure regulator sets downstream pressure, and a lubricator adds oil mist for downstream air tools and cylinders. This 300-size unit has PT1/4 (1/4 in) ports with PT thread as the standard, a differential-pressure drain on the filter bowl, a round pressure gauge reading in psi, and a mounting bracket included. The maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series is available in 200, 300, 400 and 600 sizes with port options from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, a 5 um filter element (code W) where finer filtration is needed, and gauge scale choices of MPa, psi or bar. Flow is published as curves rather than a single rating, so ask us to confirm flow and 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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: GF300-08 filter, GR300-08 regulator and GL300-08 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.

On a production press line, the GC30008LC2 cleans water and chips out of the shop air, holds a set low pressure on the clamping circuit, and mists oil to keep the clamp cylinders sealing and moving smoothly shift after shift.
Feeding the air cylinders on a cartoner or case packer, this unit filters condensate from the header line, regulates the pressure the packaging OEM specified, and lubricates the actuators that cycle the flaps and seals all day.
At a bench drop feeding impact drivers and nutrunners, the combination keeps grit and water out of the tools, sets a stable low working pressure for consistent fastening, and delivers oil mist so the tool motors last longer between rebuilds.
Size and port: the 300 size with PT1/4 ports suits lines plumbed in 1/4 in; step up to 400 or 600 when the circuit demands more flow capacity, since larger sizes carry larger ports. Drain: this unit uses the differential-pressure drain (the default), which spits condensate when the pressure differential across the filter rises; choose automatic (code A) or manual (code M) if your maintenance routine suits those better. Filter grade: 40 um is standard here; specify the W code for the 5 um element where downstream equipment needs finer protection. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are alternatives. Thread: PT is the standard; G (BSPP) and NPT are order options. The L code marks this as the low-pressure regulator type - its exact adjustment range is not published, so confirm it with us before ordering. As always, flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and line conditions and we will confirm the flow and datasheet figures for the GC300 size on request before you order.
The L code marks this as the low-pressure regulator type rather than the standard type; its exact adjustment range is not published, so confirm the range with us for your setpoint. The C2 code means a round external gauge reading in psi is fitted; an embedded square gauge is the standard alternative, with MPa, psi or bar scales available.
