The AirTAC GC30008C2WK AirTAC F.R.L. Combination, PT1/4, 5 um 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30008C2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This configuration is the GC300 size with a PT1/4 (1/4 in) port, PT thread as standard, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain on the filter bowl, a fitted round gauge reading in psi, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, a reverse/check valve fitted, and a mounting bracket included. The polycarbonate bowls suit the non-freezing -5 to 70 C operating range, with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GC line is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options across drain type, 40 um or 5 um filtration, gauge style and scale, thread (PT standard, G or NPT to order) and check valve. Flow is published as curves rather than a single rating, 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. 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.

| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Feeding spray guns and atomising headers on a finishing line, where the 5 um element, regulated pressure and oil misting in one set keep the air supply consistent across the booth.
Conditioning the air feeding pick-and-place cylinders and vacuum generators on a packaging conveyor, with the check valve holding the circuit if the plant supply drops.
Supplying filtered, regulated and lubricated air to clamping fixtures and pallet-changing actuators on a CNC cell, with the psi gauge giving operators a local setpoint readout.
Size 300 with a 1/4 in PT port is the mid step of the GC range; step up to 400 or 600, or down to 200, as your line's flow demand and piping dictate. This unit already carries the finer 5 um element (the standard is 40 um), a differential-pressure drain that bleeds the bowl automatically as pressure drops across the element, and a psi-scaled round gauge; embedded square gauges with MPa/psi/bar scales are the catalogue alternative. The fitted reverse/check valve holds downstream pressure if the supply is lost. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the bracket is included.
Sizing honestly: AirTAC publishes flow for this family as curves, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet curve and sizing against it 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.

Both are read from the code. The C2 in GC30008C2WK specifies the optional external round gauge with a psi scale (embedded square gauges with MPa, psi or bar scales are the standard alternative), and the W specifies the 5 um filter element instead of the 40 um standard. The K adds a reverse/check valve, and the blank drain position means the differential-pressure type.
