The AirTAC GC30008AF2WK 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 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30008AF2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one complete air-treatment set. This size 300 unit has a PT1/4 (1/4 in) port with standard PT thread. The filter section carries a 5 um element (code W) with an automatic drain, so collected condensate is discharged without manual intervention. The standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) and is fitted with an embedded square gauge scaled in psi, and a reverse/check valve is included. 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 are polycarbonate (PC) on this size.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with options including thread type (PT standard, G and NPT to order), drain type, filter grade and gauge scale. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the 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: GF300-08 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 clean, regulated and lubricated air to pneumatic clamps, tool-changer cylinders and chip-clearing jets on a CNC machining centre, with the 5 um element protecting fine spools and the psi gauge giving the operator a direct setpoint readout.
Supplies treated air to the pick-and-place cylinders, sealing jaws and diverters on a cartoning or case-packing conveyor, where the automatic drain keeps condensate out of the valves during continuous multi-shift running.
Conditions the supply to impact wrenches, nutrunners and air ratchets at an assembly workstation: the regulator holds steady tool pressure, the lubricator carries oil mist to the tool motors, and the check valve holds downstream pressure if the main supply drops.
Choose the size and port step against the air consumption of the downstream circuit: this unit is size 300 with a PT1/4 (1/4 in) port; larger sizes (400, 600) carry larger ports for higher-demand circuits. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering. This configuration already includes the 5 um (W) filter element instead of the 40 um standard, an automatic drain instead of manual or differential-pressure drain, a square gauge scaled in psi (MPa and bar scales are the other options), and a reverse/check valve. Thread is standard PT; G (BSPP) and NPT are catalogue options to order. A mounting bracket is included with this size.
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 performance curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote for this model. Send us your application details and we will confirm the datasheet flow curve and sizing on request before you order.
The A in the code GC30008AF2WK specifies an automatic drain on the filter bowl, which discharges collected condensate on its own - useful where the unit is mounted in a hard-to-reach spot or runs unattended. The GC series also offers a manual drain (code M) and a differential-pressure drain (blank code) if you prefer those behaviours; the choice is made in the model code when ordering.
