The AirTAC GC300C08ALC2GK AirTAC F.R.L. Combination Unit G1/4 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 GC300C08ALC2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one filtered, regulated and lubricated air-preparation set. This size-300 configuration is built for 1/4 in ports with G (BSPP) threads, and PT is the standard thread with G and NPT available as order options. The filter carries a 40 um element with an automatic drain, so collected condensate is discharged without manual attention. The regulator is the low-pressure type, suited to circuits that run below standard regulator settings, and it is fitted with an external round gauge scaled in psi. A reverse/check valve is fitted, and the unit includes a mounting bracket. 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 family is offered in sizes 200, 300, 400 and 600, with port sizes stepping up from 1/8 in through 1 in, and with choices of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard, G or NPT to order) and bracket. Flow for this series is published as curves rather than a single rated figure, so ask us to 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.

Feeds filtered, regulated and lubricated air to the pneumatic cylinders and air fittings on a bench assembly cell, with the 40 um element and automatic drain keeping condensate and particulate out of the actuators.
Sits at the drop of a packaging or cartoning conveyor line, conditioning the air that drives box-flap cylinders and clamps, with the lubricator metering oil mist to keep seals and bores working over long shifts.
Prepares the air for low-pressure clamping and workholding circuits on a machine tool, where the low-pressure regulator type, psi-scaled gauge and check valve hold the circuit steady during the cutting cycle.
Start with the port and size step: this unit is size 300 with 1/4 in ports, and the GC family steps through 200/300/400/600 with ports from 1/8 in to 1 in, so match the size to the pipe and the air demand of the circuit. The filter here uses the standard 40 um element; a 5 um element (code W) is available if the downstream equipment needs finer filtration. Drain choice matters: this configuration has an automatic drain, but manual and differential-pressure drains are also offered in the family. The regulator in this code is the low-pressure type (code L); its exact adjustment range is not published in the material we hold, so confirm it with us against your circuit pressure before ordering. The gauge fitted is the external round type scaled in psi; embedded square gauges and MPa or bar scales are the other catalogue options. Thread is G (BSPP) here, with PT as the standard and NPT available to order, and the bracket is included. Flow for the GC series 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-C0 regulator with a GF300-C0 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Ask us and we will confirm the datasheet and the flow curve for the GC300 size against your application before you order.
A GC is a three-piece combination: a separate filter, a separate regulator and a separate lubricator, each of which can be serviced or replaced on its own. A GFC is a two-piece filter-regulator plus lubricator. This GC300C08ALC2GK adds the low-pressure regulator type, an automatic-drain 40 um filter, a round psi gauge and a fitted check valve, so it suits circuits that want full filtration, regulation and lubrication with independent servicing.
