The AirTAC GC FRL Unit GC300C08N 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).
GC is the AirTAC three-unit F.R.L. combination: a separate air filter, a pressure regulator and a lubricator assembled as one conditioned-air set. This GC300C08N is a size 300 set with 1/4 in PT ports, the default differential-pressure drain on the filter bowl and the standard 40 um filter element; no gauge and no reverse valve are included in this code. The set carries compressed air at up to 1.0 MPa (145 psi) working pressure, and with the differential-pressure drain the regulator adjusts across 0.15-0.9 MPa (20-130 psi). Filter and lubricator bowls are polycarbonate at size 300, and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be specified with differential-pressure, automatic or manual drains, a finer 5 um (W) element, an embedded square gauge or an external round gauge with MPa, psi or bar scales, a reverse (check) valve, and G (BSPP) or NPT threads as catalogue options. AirTAC publishes flow for this series as curves rather than a single rating, so we confirm sizing 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. 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.

Filtering, regulating and lubricating the air at a wall drop that runs impact wrenches, ratchets and drills in a maintenance shop, with condensate handled by the differential-pressure drain.
Feeding treated air to the jets of a vibratory part-feeding bowl on an assembly line, where the regulator is set once at commissioning and the set runs unattended between services.
Conditioning shop air on a test bench used to exercise pneumatic actuators and check trailer-mounted components, with the 40 um element and differential-pressure drain suiting an intermittently used rig.
This is the GC series at its baseline configuration: the 300 body with 1/4 in PT ports, the standard 40 um element, and the default differential-pressure drain, which handles condensate without a manual walk-round - the alternative to ordering M (manual) or A (automatic). With this drain type the regulator range is 0.15-0.9 MPa (20-130 psi). If you want a local pressure readout, note that the N in this code means no gauge is fitted; the catalogue options are an embedded square gauge or an external round gauge with MPa, psi or bar scales. PT is the standard thread; G (BSPP) and NPT are available to order as specifications. Flow is published as curves, not a single rated figure, so ask us to confirm sizing against your demand before ordering.
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 GC series flow as curves against pressure rather than a single rated figure, so we do not quote a number here. Send us your peak flow demand and working pressure and we will confirm the correct size and datasheet figures on request.
N means the set is supplied without a gauge on the regulator. Catalogue options across the GC series include an embedded square gauge or an external round gauge with MPa, psi or bar scales, plus drain, filter grade and thread choices.
