The AirTAC GC30008LC2WGK AirTAC F.R.L. Combination, G1/4 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30008LC2WGK is a three-piece F.R.L. combination that filters, regulates and lubricates compressed air in one assembled set: a separate filter, regulator and lubricator. This 300-size unit is configured for a G1/4 (BSPP) port, and the filter element is the fine 5 um grade (code W) with a differential-pressure drain that bleeds collected water automatically as flow passes through. The regulator is the low-pressure type and carries a round pressure gauge reading in psi, and a reverse/check valve is fitted to hold downstream pressure if the supply drops. A mounting bracket is included.
This is a genuine AirTAC part. The GC series is available in 200, 300, 400 and 600 sizes with a choice of ports, threads (PT standard, G and NPT to order), drain types, filter grades, gauge styles and scales, so a matching configuration can be specified for most lines. 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. 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.

|---|---|
| 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 a stamping or clamping station where the fine 5 um element protects precision air cylinders and the check valve holds the clamp circuit if the main supply dips.
Conditions the air supplying carton-forming and case-sealing cylinders on a packaging conveyor, with the lubricator misting the actuator seals through every shift.
A single conditioned drop for a workbench of impact drivers and air ratchets: filtered to 5 um, regulated at low pressure for delicate fastening, and oiled for tool life.
Start with the port step: within the GC range, moving from size 200 to 300 to 400 to 600 buys a larger port and more flow, so size the unit against the air demand of the machine it feeds. This unit is already set for G1/4. Where moisture carry-over matters, choose the 5 um element as fitted here instead of the 40 um standard; where drainage is a concern, compare the differential-pressure drain fitted here with the automatic (A) and manual (M) options. The low-pressure regulator type (L) suits circuits that run below standard line pressures, and the round psi gauge here can be swapped for an embedded square gauge or an MPa/bar scale. PT is the standard thread; G and NPT are catalogue options to order. 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 this series as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and the air demand of the equipment it will feed, and we will confirm the sizing from the datasheet on request.
The L in the code marks the low-pressure regulator type, intended for circuits that run below standard line pressures; its exact adjustment range is not published, so confirm it with us for your setpoint. The W marks the fine 5 um filter element instead of the 40 um standard, for applications where finer water and particulate removal protects downstream equipment.
