The AirTAC GC30015LF2WGK AirTAC F.R.L. Combination, G1/2, 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 PT1/2" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled into one supply unit. This GC300 configuration is built for 1/2 in (G1/2) ports with G (BSPP) thread - PT is the catalogue standard thread and NPT is an order option - and carries the 5 um filter element (code W) in place of the 40 um standard, a differential-pressure drain, the low-pressure (L) regulator type, an embedded square gauge scaled in psi, a reverse/check valve (code K) and a mounting bracket. The filter and lubricator bowls on this size are polycarbonate (PC).
This is a genuine AirTAC part. The GC range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge scale options in MPa, psi or bar, and G, PT or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet for your application.

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.

| 15 | Port size PT1/2". 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. |
| 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: GF300-15 filter, GR300-15 regulator and GL300-15 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 spray guns and air-assisted applicators on a paint line, where the 5 um element, regulated low-pressure supply and oil-mist lubrication condition the air reaching the gun at each booth drop.
Supplies the cylinder and valve circuits that drive stoppers, pushers and lift gates along a bottling conveyor, with the regulator holding set pressure and the lubricator misting the actuators in continuous duty.
Mounted on a CNC machine tool's air preparation panel, the combination conditions shop air feeding clamps, tool changers and purge circuits, with the reverse/check valve fitted in the downstream circuit.
Step through GC200, GC300, GC400 and GC600 to match the port and flow band your line needs; this unit sits at 1/2 in G thread. Choose the drain: differential-pressure (fitted here), automatic for unattended condensate removal, or manual where you want positive control. Pick 40 um for general line protection or 5 um (this unit, code W) for finer conditioning, and set the gauge scale to MPa, psi or bar - this unit is fitted with a square psi gauge. The L code marks the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us. The reverse/check valve (K) and mounting bracket are included. Flow is published as curves, not a single rating - 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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and the air demand of your equipment and we will confirm the sizing from the datasheet on request.
The L in GC30015LF2WGK marks the low-pressure regulator type. The catalogue does not publish a separate adjustment figure for this variant, so we confirm the range on request. What is fixed for the unit: maximum inlet pressure of 1.0 MPa (145 psi), -5 to 70 C operation, and the embedded square gauge scaled in psi.
