The AirTAC GC30008LF2 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 GC30008LF2 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This size 300 unit carries 1/4 in PT ports and treats compressed air in three stages - the filter removes water and particulate down to the standard 40 um grade with a differential-pressure drain and a polycarbonate bowl, the low-pressure type regulator sets downstream pressure and is read on the fitted square gauge scaled in psi, and the lubricator adds oil mist for downstream air tools and cylinders. Maximum inlet pressure is 1.0 MPa (145 psi), with an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include G or NPT thread, a 5 um filter element (code W), automatic or manual drains, gauge scale in MPa or bar, and a reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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 assembly-line drops that run pneumatic impact wrenches, ratchets and air cylinders, giving each station filtered, pressure-set and oil-mist-lubricated air from one 1/4 in connection.
Supplies the carton-sealing, case-packing and diverting actuators on a packaging conveyor, where the filter keeps debris and water out of valves and the lubricator keeps cylinder seals working.
Conditions the bench air feeding clamps, air vices and hand-held tools in a machine shop, with the low-pressure regulator holding a gentle set pressure and the square psi gauge giving a clear local reading.
Choose the size by port and required flow: this size 300 unit takes 1/4 in PT ports, while sizes 200, 400 and 600 step up or down in port and flow capacity. For the filter stage, the standard element is 40 um; specify code W if the application needs 5 um. Drain choices are differential-pressure (the default on this unit), automatic (code A) or manual (code M). The regulator in this configuration is the low-pressure type (code L); the exact regulation range for the low-pressure type is not published, so confirm it with us against your set pressure. The fitted square gauge is scaled in psi here; MPa or bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options; a mounting bracket is included. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application 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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so there is no one rated flow number we can quote for this size 300, 1/4 in unit. Tell us your application and we will confirm the relevant figures from the datasheet on request.
The L marks the low-pressure type of regulator, and the exact regulation range for the low-pressure type is not published - we can confirm it on request. The drain on this unit is the differential-pressure type, the standard option; automatic (A) and manual (M) drains are available as code choices if you prefer.
