The AirTAC GC30008AC2K AirTAC F.R.L. Combination, 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 PT1/4" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30008AC2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator built as one set. This size 300 configuration is ported PT1/4 (1/4 in, PT standard thread), carries the standard 40 um filter element with an automatic drain, and is fitted with a round pressure gauge scaled in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), a reverse/check valve (code K) is included, and a mounting bracket comes with the set. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The filter and lubricator bowls on this size are PC (polycarbonate).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with ports stepping from 1/8 in up to 1 in, and with options including manual or differential-pressure drains, a 5 um filter element (code W), square embedded gauges with MPa, psi or bar scales, G (BSPP) and NPT threads, and low-pressure regulator types. Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet figures 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: GF300-08 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.

At point-of-use drops feeding air tools and cylinders on a final assembly line, this three-unit set filters water and particulate from the supply, holds a steady regulated pressure for consistent tool torque, and carries oil mist to lubricate impact wrenches and ratchets through the shift.
On a bottling or cartoning conveyor, diverters, pushers and stop gates run on compressed air around the clock. This set conditions the line supply in one pass, with the automatic drain handling condensate so the pneumatics stay dry, regulated and lubricated without an operator visiting the bowl.
CNC machining cells use compressed air for tool-clamp cylinders, chip-blast nozzles and air springs. Feeding the machine through this F.R.L. set removes water and swarf-carrying particles, keeps clamp pressure stable within the regulator range, and lubricates the actuated circuits, with the check valve holding the line during momentary supply dips.
Size and port: this size 300 set is ported PT1/4; the G-series steps through 200/300/400/600 with larger ports for larger air demand. Drain type: this unit has an automatic drain (code A); manual and differential-pressure drains are the other catalogue choices. Filter grade: 40 um is standard here, with 5 um (code W) available where finer filtration is needed. Gauge: this set carries a round gauge scaled in psi; embedded square gauges and MPa or bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and a bracket is included. Flow is published as curves, not a single rating, so 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 GC300 as curves, not as a single rated figure, so we do not quote a number here. Send us your air consumption and working pressure and we will confirm from the datasheet whether this PT1/4 set is correctly sized, or whether a larger size in the family is the better match.
The A is the drain code: this filter is fitted with an automatic drain, which expels collected condensate on its own instead of waiting for someone to open the bowl. Manual and differential-pressure drains are the other catalogue choices; automatic is the usual pick for unmanned or hard-to-reach installations.
