The AirTAC GC30010LF2WGK AirTAC F.R.L. Combination Unit, G3/8, 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 PT3/8" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30010LF2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This size-300 configuration carries a G3/8 (BSPP) port, a 5 um filter element (the finer of the two published grades), a differential-pressure drain on the filter bowl, and a low-pressure-type regulator fitted with an embedded square gauge scaled in psi. A reverse/check valve is fitted, and a mounting bracket is included. The bowls on the 300 size are polycarbonate (PC).
This is a genuine AirTAC part. The GC family is published in sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 inch, manual or automatic drain options, 40 um standard or 5 um (W) filter elements, round or square gauges scaled in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, 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.

|---|---|
| 10 | Port size PT3/8". 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). |
| F | Gauge shape: Square. 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. |

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: GF300-10 filter, GR300-10 regulator and GL300-10 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 filtered, regulated and lubricated air to the tool-clamp and pallet-change circuits of a CNC machining center, where the 5 um element protects tight valve clearances and the lubricator mists the actuator internals.
Supplying the divert and stopper cylinders on a packaging conveyor line, with the low-pressure regulator holding a gentle set pressure and the psi gauge giving operators a direct local readout.
Serving individual air drops on a textile weaving floor, where the three-unit set cleans the mill air supply, regulates it to loom requirements and keeps cylinder seals lubricated across long shifts.
Start with the size and port: 200, 300, 400 and 600 step up in both port size and flow capacity, so match the step to the air demand of the circuit - here a 3/8 in G-thread connection. Next choose the drain: differential-pressure (this unit, draining as flow differential builds), automatic, or manual. Filter grade is 40 um standard or 5 um (code W) where finer particle capture is needed - this unit carries the 5 um element. The regulator in this code is the low-pressure type; its exact adjustment range is not published, so confirm it with us against your set pressure. Gauge scale (MPa, psi or bar), thread family (PT standard, G or NPT to order), bracket and reverse/check valve complete the decode. 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for this family as performance curves rather than a single rated figure, so we do not quote one number. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet curves on request before you order.
L is the low-pressure regulator type, suited to lower set pressures than the standard version; its exact adjustment range is not published, so confirm it with us. W is the 5 um filter element, the finer option alongside the 40 um standard. K means a reverse/check valve is fitted, holding downstream conditions if supply pressure is lost.
