The AirTAC GC30008LC2GK AirTAC F.R.L. Combination G1/4 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 GC30008LC2GK is an AirTAC GC three-unit F.R.L. combination: a separate filter, regulator and lubricator built as one air-preparation set that removes water and particulate, regulates pressure and adds oil-mist lubrication to compressed air. This configuration is built on the GC300 size with G1/4 (1/4 in) G-thread ports, a 40 um filter element, a differential-pressure drain on the filter bowl, a low-pressure type regulator, a round gauge scaled in psi, and a reverse (check) valve fitted to hold downstream pressure. The polycarbonate bowls suit the 300 size, the maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and a mounting bracket is included.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options that include automatic, manual or differential-pressure drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for 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. 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.

Feeds glue-head and sealing cylinders on a carton packaging line where the circuit runs at reduced pressure. The filter clears water and pipe scale before the valves, the low-pressure regulator holds the set point the adhesive equipment was set up for, and the lubricator mists the cylinder seals.
Prepares air for diverter and pusher cylinders along a bottling conveyor. The 40 um element keeps condensate and particulate out of the directional valves, the check valve holds the downstream circuit during an upstream dip, and the psi gauge gives the line technician a readable set point.
Sits at the drop of an assembly bench running impact drivers, nutrunners and air ratchets. The filter protects the tools from water and grit, the regulator sets the working pressure the torque procedure calls for, and the oil mist lubricates the tool motors through a shift of continuous use.
Choose the GC size by port and required flow: this unit is size 300 with G1/4 G-thread ports, and larger sizes carry larger ports and more flow. The filter bowl drain is differential-pressure as coded here; automatic (A) and manual (M) drains are alternatives. The standard filter grade is 40 um, with a finer 5 um element ordered as code W. The regulator in this code is the low-pressure type (L) rather than the standard type, and the round gauge is scaled in psi (MPa and bar scales are alternatives). Threads: PT is the AirTAC standard, with G and NPT available as order options - this unit is specified with G. A mounting bracket is included. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing against 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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote a number here. Send us your application - port size, downstream demand and pressure window - and we will confirm the flow data from the datasheet before you order.
The L code selects the low-pressure version of the regulator instead of the standard type. The exact adjustment range for this low-pressure variant is not published in the standard tables, so we confirm it from the datasheet on request. The rest of the decode is unchanged: G1/4 G-thread ports, 40 um filter, differential-pressure drain, round psi gauge, fitted check valve and included bracket.
