The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008ALC1W) is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with PT1/4" ports, a 5 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).
GFC30008ALC1W is a genuine AirTAC GFC two-unit air-preparation set for compressed air: a filter-regulator that removes water and fine particulate and holds downstream pressure, plus a separate lubricator that meters oil mist to downstream equipment. This 300-size set has PT1/4 ports, an automatic drain, the finer 5 um filter element (the W option), the low-pressure regulator type and the external round pressure gauge scaled in MPa.
You are buying a genuine AirTAC part from the G series, which spans 200, 300, 400 and 600 sizes with PT, G (BSPP) or NPT threads, 40 um standard or 5 um filtration, automatic, manual or differential-pressure drains, and square or round gauges in MPa, psi or bar scales. The filter-regulator bowl on this 300 size is polycarbonate. Inlet pressure is rated to 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so send us your application and we will confirm sizing, the low-pressure set-point band and datasheet figures 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. The set has no separate bracket code — the two 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.
| GFC300 | G-series two-unit set, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic 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. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT 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 set. Constituent units, orderable separately as spares: GFR300-08 filter regulator and GL300-08 lubricator.
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Feeds clean, regulated, lubricated air to the pick-and-place cylinders on a laboratory sample-handling bench, with 5 um filtration guarding sensitive pilot valves.
Supplies fine-filtered, low-pressure regulated air to hold-down clamps on a PCB test fixture, keeping moisture and particles away from the actuator circuit.
Prepares air for the ejector and gate cylinders on a product sorting line, with the automatic drain and 5 um element supporting the pilot valves.
Choose the W code when the 40 um standard element is too coarse for the valves and cylinders downstream - this set carries the 5 um element. Otherwise the same choices apply: the 300 frame with 1/4 in ports from the G series range of 200, 300, 400 and 600; the low-pressure regulator type for reduced set-point circuits (set-point band confirmed from the datasheet on request); and the automatic drain for unattended condensate removal, with manual and differential-pressure drains as the alternatives. The round gauge is scaled in MPa, and other scales are orderable. PT thread is standard, with G (BSPP) and NPT as catalogue options. Flow is published as curves, not one 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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR300-08 filter regulator on its own.
AirTAC publishes flow for this series as curves rather than a single rated figure, so there is no one number to quote. Share your line pressure, port size and downstream demand and we will confirm the flow curve and datasheet figures for this exact model on request.
The W ending on GFC30008ALC1W decodes as the 5 um filter element instead of the 40 um standard, giving finer particulate removal for pilot valves and precision actuators. If your application is general plant air, the same set without W uses the standard element.
