The AirTAC AirTAC GC300C08LF2W F.R.L. Combination Unit PT1/4 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 GC series is AirTAC's three-unit F.R.L. combination: a separate filter, pressure regulator and lubricator built up as one air-preparation set, so the air is cleaned, regulated and oiled in that order. This GC300C08LF2W is the 300 size with a PT1/4 (1/4 in) PT thread. It carries the 5 um filter element (code W instead of the 40 um standard), a differential-pressure drain on the metal filter bowl, the low-pressure type regulator, and an embedded square gauge reading in psi. A mounting bracket is 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 family runs from the 200 through the 600 size, with ports from 1/8 in to 1 in and options across the range: 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or external round gauges with MPa, psi or bar scales, and G or NPT thread options in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure 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. 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.

A bench or cell-mounted press running on shop air needs one point where the supply is cleaned, set to the clamp circuit's working pressure and oiled. This three-unit set does all three at the cell inlet, and the 5 um element protects the directional valve stack from particulate carryover.
Carton formers, case sealers and diverters run many small cylinders through long shifts. The filter's differential-pressure drain keeps condensate out of the line without an operator visit, the regulator holds a steady supply pressure, and the lubricator mists oil to keep cylinder seals from drying out.
Weld guns, clamps and positioner drives in a robotic cell share one drop from the shop main. An F.R.L. at the cell protects the valve manifold from water and dirt, and the psi gauge lets a technician read and set the clamp pressure locally at the cell.
Size and port set the air capacity: this unit is size 300 with a PT1/4 port; step up to the 400 or 600 size when the line needs more capacity, and match the port to your piping (PT is the standard thread, with G/BSPP and NPT available as catalogue options to order). The filter drain on this unit is differential-pressure, which bleeds the bowl automatically as the pressure differential builds; automatic (A) and manual (M) drain versions exist if your maintenance routine prefers them. Filtration is the 5 um element (code W) rather than the 40 um standard - choose 5 um where downstream valves and cylinders need finer protection. The regulator is the low-pressure type; its exact adjustment range is not published in our data, so confirm it against your set pressure with us. The gauge is the embedded square type reading psi; MPa and bar scales and an external round gauge are options. Flow is published as curves, not a single rating - send us your flow and pressure requirements and we will confirm sizing from 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-C0 regulator with a GF300-C0 filter on that branch.
AirTAC publishes capacity for the GC series as flow curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your working pressure and the flow your line needs, and we will confirm the correct size against the datasheet curves on request before you order.
The L in the code means the regulator is the low-pressure type, intended for circuits set below the standard regulator band. The exact adjustment range for this type is not published in our data, so confirm your set pressure with us and we will verify it from the AirTAC datasheet. Everything else on this unit decodes normally: 5 um filtration, differential-pressure drain, square psi gauge and a PT1/4 PT thread.
